Connecting the I/O connector
For the input and output of the GT2-100N/100P, use OP-22185 (MIL socket
connector 20-pin) sold separately.
For the information on how to assemble the connector and how to connect
the power cable, refer to "GT2-100 Series User's Manual".
● Pin arrangement of I/O connector
Refer to page 15 of this manual for details about I/O circuits.
Connecting Three or More Heads
• Two heads can be connected to the amplifier unit (GT2-100N/100P)
as standard.
• When adding three or more heads, use the optional head expansion
board (GT2-E3N/E3P) sold separately to the rear of the amplifier.
• Three heads can be added to one head expansion board. Up to
three head expansion boards can be added. So the maximum of
eleven heads can be added.
