RPC-4850-8N Remote Power Controller - User’s Guide
4.2 Connecting Switched Devices to the RPC-4859-8N
Make certain that the power supply to the RPC unit is switched Off, and
then connect the supply cables from your -48 VDC powered devices to the
Switched Output Circuits on the RPC back panel. Check to make certain that
cables are securely attached, and then install the protective covers over each
output terminal block. The protective covers are held in place by screws that
pass through the holes in the cover and then thread into the screw receptacles
at the end of each Output Terminal Block.
4.3. Serial 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
Use the supplied null modem cable to connect your PC Console port to the
RPC Console (RS232 Port.) Make certain that the Serial Port Mode is set to
"Console" as described in Section 5.3.2.
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
parameters as the RPC Console Port. Make certain that the RPC Serial Port
Mode is set to "Modem" as described in Section 5.3.2.
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
RPC includes a default IP address (192.168.168.168) and a default subnet
mask (255.255.255.0.) When installing the RPC in a working network
environment, it is recommended to define network parameters as described in
Section 5.3.4.
Note: The RPC features a 10Base-T, Half Duplex 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 RPC installation instructions. Please proceed to the next
Section for instructions regarding unit configuration.
