SW2 DIP Switch Settings SW2 is an 8-position DIP switch. Table 2-3 shows the modem switch settings for DIP switch SW2. A description of the SW2 switch settings follows the table. Table 2-3. Modem Switch Settings for DIP Switch SW2 Switches SW2-1: FSK Mode (page 18) SW2-2: Receiver Squelch (page 18) - Page 17 Installation SW2-1 FSK Mode SW2-1 ON = ITU-T V.23 mode OFF = Bell 202 mode The modem has two FSK modes: Bell 202, which supports data rates from 0 to 1800 bps ITU-T V.23, which supports data rates from 0 to 1200 bps SW2-1 configures the modem for either of these FSK modes.
- Page 18 wire, half-duplex mode (SW3-7 ON), the modem squelches the receiver after RTS is turned off to prevent far-end echoes from causing data errors. The duration that the modem squelches the receiver is either: 8 milliseconds if the modem is configured for Bell 202 mode (SW2-1 OFF) 150 milliseconds if the modem is configured for ITU-T V.23 mode (SW2-1 ON)
- Page 19 Installation When the modem is configured for V.23 operation (SW2-1 ON), the RTS-CTS delay is fixed at 33 ms. SW2-6 FSK CD Delay (Bell 202 Mode Only) SW2-6 ON = 23ms OFF = 6ms SW2-6 selects the FSK CD delay and is valid when Bell 202 mode is active (SW2-1 OFF).

SW3 DIP Switch Settings SW3 is a 10-position DIP switch. Table 2-5 shows the modem switch settings for DIP switch SW3. A description of the SW3 switch settings follows the table. Table 2-5. Modem Switch Settings for DIP Switch SW3 Switches SW3-1: Fast Poll/FSK (page 22) SW3-2: Data Rate (page 23) - Page 21 Installation SW3-1 − Fast Poll Auto Rate/FSK SW3-1 ON = Low-Speed Mode (FSK) OFF = High-Speed Mode (Fast Poll) The modem has two operating modes: FSK mode, which supports data rates from 0 to 1800 bps. Fast-poll mode, which supports data rates of 4800 and 9600 bps. SW3-1, along with the Data Rate Selector (DRS) pin on the modem’s RS-232 connector, configures the modem for either FSK or fast-poll mode.
- Page 22 SW3-2 − Data Rate (Fast-Poll Mode Only) SW3-2 ON = 4800 bps OFF = 9600 bps SW3-2 configures the modem speed. When the modem is in high- speed fast-poll mode (SW3-1 OFF), setting SW3-2 ON selects 4800 bps, while setting SW3-2 OFF selects 9600 bps. SW3-3 −...
- Page 23 Installation SW3-5 − Transmitter Termination SW3-5 ON = Switched by RTS OFF = 600 Ω SW3-5 is used for multi-point configuration networks. When multiple modems are connected on the same metallic circuit: The transmitter termination should be of high impedance if the modem is not transmitting.
- Page 24 SW3-8 − Carrier Control SW3-8 ON = Constant OFF = Switched SW3-8 selects either constant or switched carrier. Constant carrier allows DTEs, such as asynchronous dumb terminals or RTUs, to operate with modems, without the input RTS signal. When constant carrier mode is enabled (SW3-8 set to ON), the modem forces the transmit carrier active and the RTS-CTS delay is minimum (<0.5 ms.).
