Table 8-1: Interface Selection - Paradise Datacom RA 5785 Operation Manual

The selected interface is controlled by a combination of internal SSPA settings and/or
Interface control pins: Baud1 (Pin e) and Baud0 (Pin j) on the J4 M&C connector (See Table
8-1).
Baud0 (Pin j) state

Chassis ground
Note: The state of these pins is sensed by the SSPA unit only at power up!
Changing the state of these pins during normal unit operation will not
affect the selected type of interface.
FSK interface allows the selection of Normal and VSAT protocols.
Note: For proper FSK interface operation, the SSPA internal settings must
be selected to 9600 Baud and Normal protocol. Do not make a connection
to interface control pins Baud1 and Baud0!
Note: For maximum ESD protection of a SSPA's Serial interface internal
circuit, the RS232/RS485 interface is isolated from the SSPA chassis
ground. Serial interface has a separate interface ground pin (Pin d on the
J4 connector). Connecting this pin to common ground will effectively
disable the protection circuit and may cause interface failure.
All interface lines are equipped with transient suppression devices.
Adding extra transient protection to communication lines is not required
and may cause interface failure!
