The serial interface is used to interface the unit to a host computer. All on-board sensors are read
through this interface, including forward power monitoring. Use of this connection is optional.

The monitor and control interface is a ten pin connector. It is a cannon type connector with a 12-10
configuration with pins (Amphenol part number 71-570123-10P). This connector is a MIL-C-26482 Series
1 receptacle, Shell size 12, 10 pins. The connector is a “receptacle” with pins (as opposed to sockets),
and requires the mating connector to be a “plug” with 10 sockets. An example mating connector would be
Amphenol #PT06A-12-10S. A range of plug-compatible Amphenol part numbers for the mating connector
may be used to add options to the plug such as right-angle, stress relief clamp, metal color/finish, etc.
Please contact the connector manufacturer for more information and/or see Amphenol catalog 12-070.
The pin outs are given in Table 2-1 .
The GND pins are internally connected to the case ground. They also provide a ground reference for the
RS-485 address signal. If the RS-485 addressing function is used, one of the GND pins should be
connected to the RS-485 ground. If the RS-485 function is not used, these pins can be left floating, or it
can be externally connected to the case ground, if desired.
