GPIB Connector pin functions are as follows:
See also GPIB/IEEE-488 Interface Connection
in Chapter 3, Test Set Operation.
Stacked Connectors
When stacking connectors to make multiple connections, ensure that excessive strain is not placed
on the GPIB socket; strain can damage the GPIB Connector, resulting in intermittent or faulty
connections.
Serial Connector
The Serial Connector is an RS-232 Data Terminal Equipment (DTE) with a 9-way D-type plug
mounted on the rear panel. Refer to Fig. 2-7 for pin locations. Software to support specific radios is
planned for future software releases.
Fig. 2-7 Serial Connector Pin Locations
Serial Connector pin functions are as follows:
Functions DTR on contact 4 and RTS on contact 7 are held at logic 1. When connecting the Test Set
to another DTE device, such as a PC, a NULL MODEM cable is required. Hard handshaking is not
implemented.
