40 CONFIGURING THE M208 FOR TCP/IP: M208 Configuration
Manual Configuration Through the COM Port
A terminal, PC, or laptop can be connected to one of the M208’s COM ports for con-
figuration purposes. A straight-through serial cable is normally needed unless a PC is
attached; in this case, a null modem cable can be used. Please see Serial Cable
Schematic on page 186 for more details.
To configure the M208 through the serial ports, you need to:
1 Configure your terminal settings according to the following specifications, unless
the COM port’s parameters have been modified on the M208:
Baud rate: 9600 Data bits: 8
Stop bits: 1 Parity: NONE
Receive handshake: XON/XOFF Transmit handshake: XON/XOFF
2 Turn on the M208 power. Wait until the STAT LED flashes regularly and then
press the <Break> key on your terminal once.
If you see garbage characters on the screen, check the baud rate and parity settings
of the terminal. If you aren’t getting anything, it may be your cable.
3 Press <Enter> for the local host (i.e. the M208) when the prompt appears asking
for an Internet address to login to.
4 Login as root when asked for a login name.
5 Press <Enter> at the password prompt. No password is required at this point, as
the M208 is still unconfigured.
6 Store the new IP address and netmask in EEPROM so that the M208 can remem-
ber its configuration after reboot. Enter:
store tcpip
ifnum
addr
ipaddress
store tcpip
ifnum
mask
netmask
ifnum is the index to a particular Network Interface. ifnum will always be 1 for
the M208 since there is only one network interface, Ethernet.
7 [Optional, but recommended] Configure root and guest user passwords with the
following commands:
set user passwd root
newrootpasswd
set user passwd guest
newguestpasswd
