Configuring
the
Modem
You configure the modem using the three sets of DIP switches on the
bottom of the modem.
,
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.
