11.0 Serial Protocol Overview
The Compact Outdoor SSPA can be managed and controlled over a variety of remote control
interfaces (see
Figure 11-1
).
Serial interface can be selected between RS-232/RS-485, Ethernet 10Base-T or FSK over
IFL input (FSK interface is available only on units with an optional L-Band block up converter).
RS-232/RS-485 interface can be used in conjunction with Paradise CO SSPA serial protocol
(aka Normal protocol) or Legacy Paradise VSAT BUC serial protocol (aka VSAT protocol).
Serial protocol format is set at no parity, 8 bit with 1 stop bit. Baud rate is selectable.
Note: Binary and Terminal protocols used on previous generation units
are no longer supported.
The Ethernet interface provides access to the SSPA unit over SNMP V1 protocol or a combi-
nation of HTTP web page access and Normal serial protocol encapsulated in the UDP frame
(aka IPNet). The Ethernet interface is fixed to the 10Base-T standard. Normally, straight-
through Cat5 cable is used to connect the unit to a network hub, and crossover Cat5 is used
to connect directly to a computer’s Ethernet port.
Note: The supplied Quick Start cable is a crossover cable designed to
connect the unit directly to a PC’s NIC card. Some network hubs and
switches are not equipped with an auto cable sense feature and may not
work with this cable!
