In stal la tion of OITs
There are two connectors for serial communications on the rear of the OIT. Both of these are D-subminiature 9-pin
connectors.
Use the supplied separate 3-position terminal block to provide power to the OIT.
Con nect the OIT to Power
The power cable for the OIT should be 18AWG, 2-conductor wire with a shield drain wire and protective shield
foil. You may buy cable P/N 6030-0009 by the foot from Maple Systems to make these.
Always run the DC ground wire directly back to the signal return of the power supply. Do not use the chassis
ground wire as your signal return.

To connect the OIT to power:
1. Connect the power cable to the OIT
a. Strip the power cable shield to expose 2" of the black and red wires.
b. Strip about ¼" of insulation from the black and red wires.
c. Thread the black and red wires through the ferrite core. The shield wire must be outside.
d. Connect the red wire to the DC positive (+) input of the OIT power terminal.
e. Connect the black wire to the DC negative (-) input of the OIT power terminal.
f. Connect the power cable shield wire to the OIT power terminal's chassis ground input.
2. Route the power cable to the OIT power supply. The power cable should not be any longer
than necessary.
3. Install the power supply wires as follows (with colors shown for Maple Systems cable P/N
6030-0009):
