APPENDIX I - RS-232 INTERFACE
The RS-232 Input-Output (I/O) connector is located on the top-center of
the Magna-Mike 8500. It is a 6 position circular LEMO style receptacle.
Insert the mating connector with the red dot upward, and push straight in
until the connector snaps into place. Withdraw the connector by pulling
straight out. Panametrics provides complete cables to connect the
Magna-Mike 8500 directly to devices with standard DB-25 male and
female connectors, as well as the IBM PC-AT 9 male pin serial I/O
connector.
Use the information below to verify compatibility with particular
equipment, and assist in constructing a custom cable if necessary.
