It is important that the voltage levels of the external trigger input
wiring be within the specified limits (see specifications on page 22)
and that a reference to ground (GND_ ) be made.
The opto-isolated trigger inputs work with a high level of +5 V. For
low level a current I
F
of 7.5
mA
≤
I
F
≤
10
mA must be driven against
ground (GND_ ).
Note: By appropriate programming one or multiple channels (up to
16 channels depending on model) can be started from any trigger
input.
3.3 Digital-I/O Section
All boards of type ME-6000/6100 with hardware version 2.6 or
higher as well as all boards of type ME-6200/6300 provide two TTL
ports with 8 bits each. Each port can be independently configured
as input or output. After power up, all ports are set to input. For
more information about programming refer to chapter 4.2 “Digital-
I/O Section” on page 20.
The both ports A and B, are available on the 20-pin flat connector
ST2 or can be routed to an additional mounting bracket (ME-AK-
D25F/S) with a D-sub 25 female connector.
