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. In default mute configuration (refer to section
Pin D:
Shutdown (i.e. Mute Control) ), use of this connection is optional.
P IN O UTS
The monitor and control interface is a ten pin connector.
CAUTION: EXTREME CARE MUST BE USED WITH THIS CONNECTOR TO AVOID ELECTRO
STATIC DISCHARGE (ESD). Many units have been damaged by improper ESD precautions. Always use
industry-standard practices including wrist straps when coming within six inches of these connectors or
any accessories or cables to be attached to this.
The connector is a cannon type connector with a 12-10 configuration with pins (Amphenol part number
71-533723-10P). This connector is a MIL-C-26482 Series 1 receptacle, Shell size 12, 10 pins. The
connector is a “receptacle” and it has pins (as opposed to sockets), and requires the mating connector to
be a “plug” with ten sockets. An example mating connector would be Amphenol #PT06A-12-10S. A range
of other 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 and shown in Figure 2-1 .
