8. RS232 Serial Interface
The RS232 Serial Interface can be used to view and set all system variables including the
individual port and network interface parameters. To use the RS232 interface you will need a
terminal adapter program such as Windows Hyper Terminal. Set up the terminal adapter
program with the following parameters:
•
Baud rate – 9600
•
Data Bits – 8
•
Stop Bits – 1
•
Parity – None
There are eight RS232 Interface commands which are listed below. All commands are not case
sensitive. For commands that report network information, NETWORK CARD NOT
INSTALLED, will be reported for systems without a network card.

and password, SNMP community names, and the system power parameters (power delivered,
power allocated, system voltage, internal temperature).
ip status
