,
IMPORTANT
It is important to follow the three
steps described below, in the order
shown, to ensure that you configure
your modem properly using the
modem DIP switches:
1.
Use DIP switch 3 (SW3) to
configure the modem for your
host DTE interface and network
topology. Using SW3, you
select the modem to operate in
high-speed fast-poll or low-
speed (FSK) mode.
2.
If you set SW3 for FSK mode
in step 1, use DIP switch 2
(SW2) to configure the modem
for either Bell 202T or ITU-T
V.23 compatibility. Otherwise,
you can use the modem in
fallback mode.
3.
Use DIP switch 1 (SW1) to
select the modem’s transmitter
output level and receiver
dynamic range. The SW1
settings apply for both high-
speed fast-poll and low-speed
(FSK) modes
.
