External synchronization signal characteristics
Signal Description Type Active
RTS
Ready To Send - Output
from EM 124 when it
is ready for the next
trigger pulse
Open collector output
from isolation unit
High
TRIG OUT Trigger out -
Output to external
synchronization system,
active while the EM 124
is transmitting Open collector output
from isolation unit Low
TRIG IN Trigger in - Input to
EM 124 enabling it to
transmit Optical isolated input High
Note
To avoid ground loops and damage of the electronics caused by external connections, all
connections are optically isolated.
Optically isolated input signals
Note
The input signals must not be negative, that is no RS-232 signals can be used for these
inputs.
A
Input from external system
B
Processing Unit input
circuitry
The input current must be approximately 10 mA. Depending on your input signal
additional resistance must be applied to achieve the required input current.
Two examples are shown to clarify.
