Configuring the JC-MER-CXB

The JC-MER-CXB consists of a computer running Linux. It has an
Ethernet port, ARCNET port and a flash disk that emulates a disk
drive. The router program is preloaded at the factory but must be
configured. For this, Planning Forms are provided in Appendix A.
You can monitor JC-MER-CXB statistics (if monitoring has been
enabled) by connecting a null-modem cable from COM2 on the front
of the unit to a COM port on a laptop or desktop computer running a
terminal- emulation program like HyperTerminal. You configure the
parameters by connecting to COM1. Remember: monitor on COM2
and configure on COM1. See Appendix D for using HyperTerminal.
Once the terminal emulator is ready, connect it to COM2 (to monitor
the boot process) then apply power to the JC-MER-CXB. After the
Statistics Screen (see Figure 15 on page 31) appears and the "Idle"
fields begin to count, move the cable to COM1, type config and press
ENTER to access the configuration screen. The bottom of the screen
displays information on using certain keys to perform editing tasks.
The left side of the screen displays the JC-MER-CXB IP address,
Subnet Mask and Existing LAN Router IP address (network gateway,
if one exists). On the right side are switches (e.g., "/S") and all
ARCNET subnet addresses and associated JC-MER-CXB IP addresses.
All of this information is stored to non-volatile memory and, except
switch settings, must be identical on all JC-MER-CXBs.
