2 The pars of he BioSim universal biological simulaor sysem The BioSim sysem is divided ino wo funcional pars. The ime parameers are generaed by he fully digial BioSim Conroller, and he analogue volage and curren sources are implemened in he End-sages. The pars of he sysem are manufacured as independen equipmens. On one hand i resuls a more flexible and variable sysem, because he similar pars (e.g. he End-sages) are compaible, and hey can be changed easily. On he oher hand he divided sysem mees he special experimenal requiremens much beer, because he analogue End-sages can be locaed close o he biological objecs in he shielded environmen, bu he digial BioSim Conroller, can be placed anywhere else. BioSim Compuer Inerface is an alernae of he BioSim Conroller in special cases. You can find deailed descripions abou each elemens of he BioSim sysem in he appropriae manuals. BioSim Conroller BioSim Conroller is a dual-processor sysem. There are wo independen RISC microconrollers buil ino one cage. One of hem, he Repeiion Cycle and Gae Conroller can be used o generae he periodical repeiion rigger evens, or i can be used as a gae generaor o enable, or disable he oupu pulse sequence. The oher microconroller is he Pulse Paern Generaor. I is used o generae he differen oupu pulse sequences (as lised below). The accuracy of he ime parameers in BioSim Conroller are guaraneed by inernal crysal pacers. All he programmed ime parameers are sored in buil-in nonvolaile memories. They hold he previously used values during swiched off periods. Easy programming operaions are carried ou in menu sysem, wih 4-buon keypads. The displays of he microconrollers are 4 x 2, and 2 x 16 characer alphanumeric models wih backligh o provide good visibiliy. BioSim Conroller (ogeher wih one of he End-sages) can be used as a sand-alone simulaor, bu boh of is microconrollers have go bi-direcional digial conrol capabiliies: Sar Inpu, Gae Inpu, and Synchron Oupu. These TT-compaible conrol bis offer a huge versailiy in he differen applicaions. BioSim Conroller can be sared exernally (wih rising edges a Sar Inpus) from anoher equipmen (for insance a PC), or i can be he maser synchron generaor (if he exernal equipmens are riggered from is Synchron Oupus), as well. BioSim Conroller has go nonvolaile memories o sore all parameers of he funcions. If you use he equipmen in a fixed applicaion, you should program i one ime only. If you swich he BioSim Conroller on, i checks, which funcion was used las ime. Afer i he parameers used by he acual funcion are checked. If he parameers have go valid values prese, he las used funcion will be sared auomaically.

3 BioSim Compuer Inerface There is an alernae equipmen, BioSim Compuer Inerface in our choice o subsiue he BioSim Conroller in ha cases, when a compuer sofware is used o generae he sequence of he simulaing pulses. BioSim Compuer Inerface has go a universal connecor o connec any of End-sages of Superech, a power supply uni o supply he End-sage, and wo TT-compaible digial inpu connecors. Is TT inpus are configured in logical OR funcion inernally. The TT sandard describes he volage, and load specificaions of he inpus, and oupus of a logic sysem, wha is supplied from 5V. Nowadays mos of he microconrollers, and logic sysems use 3.3V of supply volage inernally. The inpus of he BioSim Compuer Inerface accep he logic levels of he 3.3V, non-sandard-tt sysems correcly, wih opimal noise margins, oo. Basically BioSim Compuer Inerface realizes he DC via Conrol funcion (see laer in his descripion) of BioSim Conroller. If a sophisicaed sofware is used, i is no necessary o insall he BioSim Conroller, i is enough o use he BioSim Compuer Inerface. The disadvanage of his arrangemen is, ha a fas compuer, and an appropriae sofware is always necessary o be used. An independen, universal, sand-alone simulaor can be formed only by using of he BioSim Conroller. Programming convenions, and definiion of erms in connecion wih he BioSim Conroller The funcions are caegorized in wo groups. The firs group conains he 'single' funcions. 'Single' funcions are iniiaed by he START even. Afer a START even hey generae heir sequence one ime only (an example is Single Burs). The oher caegory is he group of he 'repeiive' funcions. They repea heir sequence periodically based on an inernal crysal pacer (an example is Coninual Burss). A subcaegory of he 'single' funcions is he group of he 'delayed' funcions. They are he same as heir appropriae 'single' equivalens, bu a programmable delay is occurring a he beginning of he sequence before he firs Oupu pulse. START even means a keypress on START buon, or a TT rising edge appearing on Sar inpu. The wo source of Sar even can be used ogeher or independenly any ime (hey are in logical OR relaion). You can clear all sored parameers if you press and hold F buon down, while BioSim Conroller is swiched on. During programming acions he equipmen checks he validiy of he acual value. If you ry o accep (wih F buon) a number ou of range, he sofware will no allow i. If more han one parameers are incoheren, you will be asked o correc hem. UP and DOWN buon is used o navigae in menus, and o modify parameer values up or down, respecively. F buon is used o selec a menu iem, or accep a parameer value. Furhermore, F buon is used o cancel a funcion if i is running. If

4 you cancel a funcion wih F buon, you will ge an access o Funcion Choice menu. START buon is used o sar he sequence of pulses, if a 'single' or a 'delayed' funcion is seleced acually. The 'repeiive' funcions can be inerruped emporarily wih START buon (and hey can be resared again wih i). The operaing modes of he Repeiion Cycle and Gae Conroller in BioSim Conroller equipmen Repeiion Cycle: This funcion can be used o generae periodical repeiive rigger evens in such cases, when he BioSim Conroller is he maser synchron generaor of he daa acquisiion process (in such cases, if he exernal daa acquisiion equipmen, such as a PC is riggered from is Synchron Oupu). In his funcion he Synchron oupu of he Repeiion Cycle and Gae Conroller provides repeiive Sar evens for he Pulse Paern Generaor, on which any of he single paerns should be seleced. To use he Repeiion Cycle funcion he Synchron Oupu of he Repeiion Cycle and Gae Conroller should be conneced o he Sar inpu of he Pulse Paern Generaor wih he appropriae swich a he back side of he BioSim Conroller. The repeiion cycle ime (Tc) can be se from 8 ms - 6 sec, wih 1 ms of resoluion. A wide (5 ms) Synchron pulse is generaed a he beginning of every Repeiion Cycles. These Synchron pulses are he synchron pulses of he whole ime sequence, if he Repeiion Cycle funcion is used, and a single paern is iniiaed on he Pulse Paern Generaor. The Repeiion Cycle and Gae Conroller has go is own TTcompaible Oupu, which is independen from he Oupu of he Pulse Paern Generaor. The Oupu pulse of he Repeiion Cycle and Gae Conroller ( milliseconds in widh, wih.1 ms of resoluion) can be used for any oher conrolling ask (for insance muing he inpu of he preamplifier for a programmed period before appearing, and during he simulaing pulse a he Oupu of he End-sage), if i would be necessary. Gae Generaor: This funcion can be used o generae a programmed enabling period for he Gaed Coninual funcion of he Pulse Paern Generaor. To use he Gae Generaor funcion he TT-compaible Oupu of he Repeiion Cycle and Gae Conroller should be conneced o he Gae Inpu of he Pulse Paern Generaor wih an exernal cable a he back side of he BioSim Conroller. This combinaion of funcions can be used o produce very long burss of pulses. The duraion of he burs is defined by he Repeiion Cycle and Gae Conroller. The iming daa of he pulses, and he pauses should be programmed a he Pulse Paern Generaor in is Gaed Coninual funcion. The gae ime (Tg) can be se from 8 ms - 6 sec, wih 1 ms of resoluion. A wide (5 ms) Synchron pulse is generaed a he beginning of every Gae periods. These synchron pulses are accessible a he Synchron Oupu of he Repeiion Cycle and Gae Conroller.

5 The operaing modes of he Pulse Paern Generaor in BioSim Conroller equipmen The acually realized 12 operaing modes are presened in he Appendix. They have go a graphical inerpreaion o explain hem in fine deails. In a few cases here are more han one funcion wih which a paradigm can be carried ou. You should always consider, which funcion is he bes one o your special ask. Furher developmen Unil now we have developed many differen operaing modes for BioSim Conroller, as i is lised above. In spie of his, if you can no find he appropriae funcion for your special ask in our acual choice, and his funcion seems o be ineresing for oher our cusomers, we will develop a special operaing mode especially for you. I is our mehod, how we improve he feaures of our equipmen. We collec all he noices and feedbacks of our cusomers, and we implemen heir (may be your) knowledge ino he feaures of BioSim. Warrany We give you full warrany service, including res pars for he period of 3 years by defaul. onger warrany periods can also be defined and agreed (he acual condiions should be discussed before placing he order).

6 DC via Conrol U ou START Inpu = Oupu is acive, while START buon is pressed, or TT high level is applied o START Inpu. This mode offers free conrol capabiliy from any oher equipmen (e.g. anoher simulaor conroller, or a TT por bi of a compuer).

7 DC by ong-timer U ou START even = T im Oupu is acive (consan DC level adjusable by he helical pomeer on he Endsage) in a programmed period, in he range of 1-6 sec, wih 1 sec of resoluion. This period sars a he beginning of he START even.

8 Wide Pulse/Pause U ou START even = T 2T 5T p p p Wide pulses, and pauses (hey are equal in widh) are generaed. The duraion of he pulses (and he pauses) can be programmed from 1-99 milliseconds, in 1 ms seps.

9 Single Pulse U ou START even SYNCRON Oupu = One Oupu pulse is generaed ( milliseconds in widh, wih.1 ms of resoluion) a he START even. A Synchron pulse (5 µs) is generaed a he beginning of he Oupu pulse. Single Pulse funcion is a special case of Delayed Pulse funcion, when delay ime equals o zero.

10 Delayed Pulse START even SYNCRON Oupu = T d A delay (1-25 milliseconds in widh, wih 1 ms of resoluion) is occurring afer START even. Jus afer he delay ime an Oupu pulse is generaed ( milliseconds in widh, wih.1 ms of resoluion). A Synchron pulse (5 µs) is generaed a he START even (a he beginning of he delay ime period). Single Pulse funcion is a special case of Delayed Pulse funcion, when delay ime equals o zero.

11 Single Burs U ou START even SYNCRON Oupu = A programmed number (2-99 pieces) of pulses are generaed a he START even. The widh of he pulses, and he pauses beween he pulses can be se in he range of milliseconds, wih.1 ms of resoluion. A Synchron pulse (5 µs) is generaed a he START even (once a he beginning of he firs Oupu pulse, in every burss). Single Burs funcion is a special case of Delayed Burs funcion, when delay ime equals o zero.

12 Delayed Burs U ou START even SYNCRON Oupu = T d A delay (1-25 milliseconds in widh, wih 1 ms of resoluion) is occurring afer START even. Jus afer he delay ime a programmed number (2-99 pieces) of pulses are generaed. The widh of he pulses, and he pauses beween he pulses can be se in he range of milliseconds, wih.1 ms of resoluion. A Synchron pulse (5 µs) is generaed a he START even (once a he beginning of he delay ime period, in every burss). Single Burs funcion is a special case of Delayed Burs funcion, when delay ime equals o zero.

13 Coninual Pulses U ou START even SYNCRON Oupu = 1/f 2/f 8/f Repeiive pulses ( milliseconds in duraion, wih.1 ms of resoluion) are generaed on Oupu. The repeiion cycle ime (Tc) can be se from 1 ms - 6 sec, in 1 ms seps. Synchron pulses are generaed a he beginning of every Oupu pulses. Coninual Pulses funcion is a special case of Gaed Coninual funcion, when BioSim Conroller ignores he Gae signal, resuling coninuous flow of pulses, beginning a START even.

14 Gaed Coninual START even GATE Inpu T x T y U ou SYNCRON Oupu = T x T +1/f x T y T +3/f x Repeiive pulses ( milliseconds in duraion, wih.1 ms of resoluion) are generaed on Oupu. The repeiion cycle ime (Tc) can be se from 1 ms - 6 sec, in 1 ms seps. Synchron pulses are generaed a he beginning of every Oupu pulses. The flow of Oupu pulses are disabled if TT low level is applied o he Gae inpu. The pulses are never broken, because an asynchronous Gae signal is synchronised inernally. Remoely conrolled burss can be realised in his funcion using anoher simulaor conroller, or a compuer. Coninual Pulses funcion is a special case of Gaed Coninual funcion, when BioSim Conroller ignores he Gae signal, resuling coninuous flow of pulses, beginning a START even.

15 Coninual Burss START even U ou SYNCRON Oupu = 1/f Repeiive burss of pulses (2-99 pulses/cycle) are generaed on he Oupu. The ime parameers of he componens in he burss are he same as in he Single Burs, and he Delayed Burs funcions. The repeiion cycle ime (Tc) can be se from 1 ms - 6 sec, wih 1 ms of resoluion. A Synchron pulse is generaed a he rising edge of he firs Oupu pulse (once a he beginning in every burss).

16 Flexible Burs START even U/I ou SYNCRON Oupu = T1 T2 T3 T4 T5 T6 T7 T8 T oal A freely defined burs of pulses can be composed in his funcion. The number of pulses in he burs can be se from 2 o 1. The lengh of he pauses, and he duraions of he pulses can be se independenly from each oher. The pauses can be programmed from.1 ms o 5. ms, wih.1 ms of resoluion. The widh of pulses can be programmed from.1 ms o 25. ms, wih.1 ms of resoluion. A Synchron pulse (5 µs) is generaed a START even a he beginning of he firs pause (in oher words a he beginning of delay ime period).

17 Variable Pulse U/I ou START even adjusable widh SYNCRON Oupu = T d A delay (1-25 milliseconds in widh, wih 1 ms of resoluion) is occurring afer START even. A Synchron pulse is generaed a he beginning of delay ime period. Jus afer he delay ime an Oupu pulse is appearing. The duraion of he Oupu pulse can be se from 1 µs o 2. ms, wih very fine, 1 µs of resoluion. The widh of he Oupu pulse can be modified on-he-fly. If you modify he pulse widh, he acual pulse will be finished wih he las duraion, bu he nex one will be produced wih he new duraion (a he nex START even).
