APPENDIX B: RS-232 CABLE AND CONNECTOR

B.1 RS-232 CABLE CONSTRUCTION

WARNING: Dangerous voltages, capable of causing death, are
present in this instrument. Use caution when handling, testing,
and adjusting.

*** NOTES ***

* Pins 5,6,20 on DB-25-S or 4,6,8 on DB-9 are tied together at the computer end.

Shield SHOULD NOT be connected at MER DECK BOX end.

WARNING:

THIS CABLE WILL PROBABLY NOT WORK WITH YOUR X-Y

PLOTTER. Consult the manual for your plotter to obtain the proper cable for its
operation. Plotter will need to be connected to the same input as the MER Deck
Box which will mean that you will need to switch devices and cables using
COM1.

SELECTION OF DTE OR DCE CONNECTOR CONFIGURATION: There are two yellow
jumpers near the RS-232 connector (J1) to select if the MER Deck Box is to be DCE (Data
Communication Equipment) or DTE (Data Terminal Equipment). This reverses pins 2 and 3 of
the RS-232 connector. The unit is shipped as a DCE device. The jumpers are installed in a
fore/aft position. Installing the jumpers in a side to side position makes the unit a DTE device.
Pin 1 is Frame and AC power ground. No other signals are connected to J1. Pins 4, 5, 6, 8,
and 20 are not connected. Three unused receivers with their input grounded are available. The
outputs are connected to pads. Likewise three unused drivers with their input grounded are
available. The outputs are connected to pads. Signal ground is connected to pin 7.
