96 DOMINION SX USER GUIDE
Local Port Connection to the Dominion SX
The local port of the Dominion SX must be connected to the COM port of a computer system, a
terminal, or some other serial capable device using a null modem cable with DB-9F null on both
ends.
If there is an RJ 45 interface, a special cable (CRLVR) is used with an ASCSDB9F connector on
the client machine. The CRLVR may also be used if RJ45-RJ45 connection to local port is
established – that is, if you connect the local port of an SX device as a serial target to another SX.
Port Settings
Ensure that the port settings (serial communication parameters) are configured as follows:
• Bits per second = 9600
• Data bits = 8
• Parity = None
• Stop bits =1
• Flow Control = None
