Rear Panel Connections
Both the signal
output and the AUX sockets are 8-pin circular
mini-DINs. The following information is provided for those wishing to
interface the Model EM-1 Econo UV Monitor with other equipment
such as integrators and non Bio-Rad fraction collectors. System Cable 7
may be used as a breakout cable, with an 8-pin mini-DIN at one end and
loose wires at the other.
Do not attempt to use the
socket for anything other than the
Model EM-1 Econo UV Monitor optics unit.
All digital inputs use TTL circuitry and are active LOW.
