Laser Command Signals
During laser bench testing, it is recommended that command signals be generated from
an Iradion Laser Controller or properly programed pulse generator. These units can
provide the tickle pulse and drive signals needed to test and operate the laser properly.
Alternatively, most motion control software packages are designed to provide the proper
pulse protocol.
The Modulation pins on both
the “D” connector,
pin 3 (low) and 4 (high),
and the RJ-
45,
pins 1 (high) and 6 (low),
are designed to allow either
floating
or
grounded
input
modes.
Both the High and Low pins should be used in either case.
A software setting
made through the RS232 interface will either ground Modulation Low or leave it floating.
Factory setting is set to ground Modulation Low.
It is possible to use the Modulation High pin only if the Modulation Low pin is grounded
by software settings or by a physical wire, however, depending on the ground integrity
of the host system and level of ground noise this may not be the best solution.
The diagram below shows the circuit of the modulation input interface:
