3.4 Setting the Interface Converter for MIL 188C Mode
Jumpers W2C through W6C are reserved for MIL 188-C mode. Refer to
Figure 3-4 for an illustration of these jumpers and to Figure 3-1 for their
position on the interface converter’s circuit board. In order for the interface
converter to operate properly with your MIL 188-C device, you must set these
jumpers for either DCE or DTE operation, depending on the DTE/DCE
status of your MIL 188-C device. To configure these jumpers simply move the
DIP shunt for each to the correct position, as marked on the circuit board.
Factory default for the MIL 188 side of the interface converter is to MIL 188-C
operation set for DTE.

3.5 Tying Together Frame and Signal Ground
Jumper JP1 is included on the circuit board in order to enable Frame
and Signal Ground to be tied together. Enabling JP1 connects 100 ohms
resistance between signal ground and frame ground. This is required in
certain special applications. In order to enable this option, simply place
the jumper’s strap onto the two header pins.
