Page 13: Sw1-1 Auto Rts
Installation SW1-1 Auto RTS SW1-1 ON = Enable Auto RTS SW1-1 OFF = Disable Auto RTS (default) For data terminals that do not provide hardware Request To Send (RTS), set switch SW1-1 to ON to enable auto RTS mode. In this mode, TXD is detected at the modem and an internal RTS signal is turned ON. -
Page 14: Sw1-4 - Soft Carrier Control
Installation SW1-4 – Soft Carrier Control SW1-4 ON = Soft Carrier is enabled SW1-4 OFF = Soft Carrier is disabled In Bell 202T mode, when soft carrier mode is enabled, a carrier frequency of 900 Hz is transmitted at the end of a transmission in order to turn off the carrier detect (CD) at the receiving modem. -
Page 15: Sw1-8 Receiver Termination Impedance
Installation This configuration should be used for all slave modems to prevent the transmitting modem from being unnecessarily burdened. To select this configuration, set switch S1-7 ON for the slave modems. If you use the modem with transmission lines that are transformer-coupled or with an impedance-isolated network (such as a transformer bridge), set switch S1-7 OFF for proper operation. -

Installation RS-232 or RS-485 Serial Interface (Standalone Only) JP2, a 6-pin header, is used to select the communication port for the modem. You may select to use either the RS-232 or RS-485 port. Only one type of interface is supported by the modem. -
Page 17: Connecting To A Transmission Line
Installation Connecting to a Transmission Line The modem has a transmission line interface (RS-11C) that can be configured for 2- or 4- wire analog connection, where in 4- wire connection, one pair (Tx-A and Tx-B) is used to transmit data and the other pair (Rx-A and Rx-B) is used to receive data. The transmit pair and receive pair are non-polarized. -
