Installation
SW2-1 − Fast Poll/FSK (high- & low-speed modes)
SW2-1 ON = Low-Speed Mode (FSK)
OFF = High-Speed Mode (Fast Poll)
SW2-1 configures the modem for either low-speed (FSK) mode or high-speed (Fast Poll) mode. As a result, the SW2-1 setting you choose determines the switch definitions for the other switches.
cFor high-speed mode, the configuration switches follow the definitions in Table 2-1.
cFor low-speed mode, the configuration switches follow the definitions in Table 2-3.
SW2-4 − Auto RTS (high-speed mode only)
SW2-4 ON = Enable Auto RTS
OFF = Disable Auto RTS
For data terminals that do not support hardware RTS, set SW2-4 to ON to enable buffer mode. In this mode, TXD is detected at the modem and internal RTS is turned ON. After training completes, the TXD is transmitted to the remote modem. The transmitter turns off if no TXD is detected after 1 character length of idle time.
SW2-6 − Production Test Only (high- & low-speed modes)
SW2-6 Must be OFF
SW2-6 must be in the OFF position for normal operation.
SW2-7 − 2-/4-Wire Operation (high- & low-speed modes)
SW2-7 ON = 2-Wire, Half-Duplex Mode
OFF = 4-Wire, Full-Duplex Mode
SW2-7 configures the modem for 4-wire full-duplex or 2-wire half- duplex operation.
