Hardware Installation
4.3. Serial Console Port Connection
The MPC's Console Port is a male, RS-232C DB9 connector, wired in a DCE
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 B.1 describes the
Console Port interface.
4.3.1. Connecting a Local PC
Use the supplied null modem cable to connect your PC COM port to the MPC's RS232
Console Port. Make certain that the Serial Port Mode is set to “Normal” as described in
Section 5.8.1.
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 parameters as the MPC
Console Port. Make certain that the MPC Serial Port Mode is set to “Modem” as
described in Section 5.8.1.
4.4. Connecting the Network Cable
The Network Port is an RJ45 Ethernet jack, for connection to a TCP/IP network.
Connect your 100Base-T cable to the Network Port. Note that the MPC includes a
default IP address (192.168.168.168) and a default subnet mask (255.255.255.0.) When
installing the MPC in a working network environment, it is recommended to define
network parameters as described in Section 5.9.
