4. INTERFACES

The SSPB provides four user interfaces that could be used to connect to several optional external

devices. The interfaces for this model are listed below:

1. Discrete Interface (J3): This interface offers the essential monitoring and control of the

SSPB by discrete signals.

2. RS-232 Interface: This interface offers to the operator the essential monitoring and control of

the SSPB using a personal computer equipped with any terminal software.

3. RS-485 Interface: This interface offers the complete monitoring and control of the SSPB and

provides the communication and remote control through the RS-485 serial communication port

in packet mode.

4. RF Output Monitor Interface: This interface provides a sample of the output power of the

unit through a 40-dB coupler.

4.1 DISCRETE INTERFACE

The Discrete Interface is located at connector (J3) on the rear panel of the SSPB (see Figure 5 at

page 24). This connector is a female, 15-pin DB-type with a pin assignment as shown in

TABLE 3 at page 19.

Pins 2, 3 and 4 of connector (J3) are of Form-A relay type outputs that provide the user an

indication informing the status of the SSPB.

Pin 1 of connector (J3) RELAY is the mute control input, allowing the user to mute or un-mute the

RF output of the SSPB.

CAUTION: If pin 1 is not connected to pin 5, the unit will remain disabled (mute).
