60 208143 REV - Operations Manual, HPA3, Mini Compact Outdoor SSPA

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).

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!
