CHAPTER 3: Installation
3.1 Installing the Converter
Before attempting to install the interface, read these steps.
1. Make sure the package came with everything that should be included.
You should have received the RS-232
↔
MIL Standard Interface
Converter, this manual, and the wall-mounted power supply (either
115 or 230 VAC).
2. Open the interface converter case by removing the two screws
on the bottom of the unit with a Phillips-head screwdriver.
3. Set the jumpers and DIP shunts for your application according to the
directions found in
Sections 3.2
through
3.5
. See Figure 3-1 for the
location of these components.
4. Replace the top of the interface converter and secure it in place with the
two screws.
5. Attach the cable from the MIL Standard device to the MIL 188 connector
on the rear of the unit.
6. Attach the cable from the RS-232 device to the RS-232 connector on the
rear of the unit.
7. Plug the 5-pin adapter of the wall-mounted power supply into the power
connector on the rear of the unit. Then plug the three-prong connector
into a wall outlet. The unit is now ready for use.
Jumpers W6 and W6C need to be set only for synchronous operation of the
converter. They play no part in asynchronous communications.
Positions for jumpers and shunts are labeled “DCE” and “DTE” on the PC
board.
For proper operation of the interface converter, the status of the RS-232 and
MIL 188 sides of the converter must be opposite each other. For example, if
the RS-232 side is set to DCE, the MIL 188 side
must
be set to DTE.
