2. EPMS-07 Modular Plug-In System 2.1. General System Description / Operation The npi EPMS-07 is a modular system for processing of bioelectrical signals in electrophysiology. The system is housed in a 19” rackmount cabinet (3U) has room for up to 7 plug-in units.
Note: The chassis of the PWR-03D is connected to protective earth, and it provides protective earth to the EPMS-E housing if connected. Figure 3: Left: PWR-03D front panel view Right: PWR-03D rear panel view. Note: This power supply is intended to be used with npi EPMS-E systems only. ___________________________________________________________________________ version 1.5 page 5...
TMR-02M User Manual ________________________________________________________________________________________________________________ 2.7. System Grounding EPMS-07/EPMS-03 The 19" cabinet is grounded by the power cable through the ground pin of the mains connector (= protective earth). In order to avoid ground loops the internal ground is isolated from the protective earth.
The TMR-02M was designed as an easy-to-use device for generating square pulses of fixed amplitude (TTL, +5 V) and variable length. The TMR-02M has two digital switches to set PULSE duration and DELAY time. The TMR- 02M can be used continuously or for a selectable number of cycles. A switch allows manual start (and stop while cycling), but the unit can also be operated using an external TRIGGER.

Note: If the thumb wheel switch is set to 000 and switch #4 is set to REPETITIVE, 1 cycle will be generated! (4) REPETITIVE / CONTINUOUS switch Switch for setting the operation mode of the TMR-02M. REPETITIVE: The timer cycles repetitively pulses: The number cycles is of set by CYCLES switch #3.

RESET: the timer is stopped and the CYCLE COUNTER is set to zero. STOP: the timer is stopped and the CYCLE COUNTER shows the number of cycles which had been carried out.
TMR-02M User Manual ________________________________________________________________________________________________________________ 4. Operation The TMR-02M module can be started either manually by pushing START (#9, Figure 5)or by a TTL HI signal (rising edge) at TRIGGER IN (TTL) (#7, Figure 5). This signal must be at least 10 µs.
