IPS-4 Internet Power Switch; User’s Guide
4.3. Console / RS232 Port Connection
The Console Port is a male, RS232C DB9 connector, wired in a DTE
configuration. In the default state, the Console port is configured for 9600
bps, no parity, 8 data bits, 1 stop bit. The Console Port can be connected to
either an external modem or a local PC, but not both items at the same time.
Appendix A describes the Console Port interface.
4.3.1. Connecting a Local PC
When connecting the Console Port to a Local PC, note that the port uses a
DTE configuration. After the Local PC has been connected, make certain to
set the Serial Port Mode to "Console" as described in Section 5.3.1.
4.3.2. Connecting an External Modem
When connecting directly to an external modem, use a standard AT to
Modem cable. Make certain that the modem is initialized at the same
default communications parameters as the IPS Console Port. Next, refer to
Section 5.3.1 and set the Serial Port Mode to "Modem". If necessary, you
may also wish to redefine the Modem initialization command at this point
as described in Section 5.3.1. Please refer to the modem user’s guide for
more information.
4.4. Connecting the Network Cable
The Network Port is an RJ45 Ethernet jack, for connection to a TCP/IP
network. Connect your 10Base-T cable to the Network Port. Note that the
IPS includes a default IP address ( and a default subnet
mask ( When installing the IPS in a working network
environment, it is recommended to define network parameters as described
in Section 5.3.4.
Note: The IPS features a 10Base-T Interface. When connecting
to a 100Base-T interface, most router switches will autosense
to determine if the device is 100Base-T or 10Base-T, and then
configure the network interface accordingly. If your router switch
does not autosense, the network interface port must be manually set
to 10Base-T.
This completes the IPS installation instructions. Please proceed to the next
Section for instructions regarding unit configuration.
