MODE SELECT connectors (see also chapter 3.4)
All MODEs OF OPERATION can be selected by TTL signals connected to the rear panel
(see below), if the MODE OF OPERATION switch (42, Figure 1) is in EXT position. This
is very convenient when switching often between electroporation and recording, because
this can be done automatically by the data acquisition system using TTL signals.
(7) R connector
S
BNC connector for remote control of the series resistance compensation circuit. A TTL HI
(+5 V) signal is connected here to activate the series resistance compensation circuit
remotely.
(8) R connector
EL
BNC connector for remote control of the electrode resistance test. A TTL HI (+5 V) signal
can be connected here to select the electrode resistance test remotely.
(9) BR connector
BNC connector for remote control of the bridge mode. A TTL HI (+5 V) signal can be
connected here to select the bridge mode remotely.
(10) OFF connector
BNC connector to switch the ELC-03XS in OFF mode remotely with a TTL HI (+5 V)
signal.
(11) x10 MODE connector
BNC connector to switch the ELC-03XS to x10 mode of operation remotely (TTL HI
signal). Dependent on the signal level at 12, this is CCx10 (signal at 12 = LOW) or VCx10
(signal at 12 = HI).
(12) VC / CC connector
BNC connector for remote control of the VC / CC mode of operation. A TTL signal can be
connected here to select the mode of operation remotely (HI = VC, LO = CC).
(13) GROUND connector
Banana plug providing internal ground (see below).
(14) CHASSIS connector
Banana plug providing mains ground (see below).
(15) FUSE holder
Holder for the line fuse. For changing the fuse rotate the holder counter-clockwise using a
screw driver.
(16) LINE SELECT switch
Switch for selecting the line voltage. Switch to the right for 230 V AC, to the left for 115 V
AC. The selected voltage is indicated on the switch.
Caution: Before turning on the instrument, make sure that the correct line voltage is selected.
