Installation Installation Summary The modem installation involves the following steps: Configuring the modem. See the section below. Connecting to a transmission line. See page 25. Connecting an RS-232 device. See page 26. Configuring the Modem You configure the modem using the two sets of DIP switches on the component side of the modem, near the center.

Installation SW1-1 through SW1-4 − Transmit Level (high- & low-speed modes) Switches SW1-1 through SW1-4 adjust the modem’s transmit level. Table 2-2 shows the transmit levels you can select using these switches. Table 2-2. Transmit Levels (High-Speed and Low-Speed Modes) Transmit Level 0 dBm −1 dBm...
Page 15
SW1-5 − Receiver Dynamic Range (high- & low-speed modes) 10 to −43 dBm − SW1-5 ON = OFF = +3 to −30 dBm For a low receive signal level, set SW1-5 to ON (−43 dBm ). For short distances or to select a strong receive signal, set SW1-5 to OFF. SW1-6 and SW1-7 −...
Page 16
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.
Page 17
SW2-8 − Carrier Control (high- & low-speed modes) SW2-8 ON = Constant OFF = Switched SW2-8 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 (SW2-8 set to ON), the modem forces the transmit carrier active and the RTS-CTS delay is minimum (<0.5 ms.).
Installation Low-Speed (FSK) Mode Table 2-3 shows the modem switch settings that can be used when the modem is configured for low-speed (FSK) mode. This mode is enabled when switch SW2-1 is set to ON. Following this table is an explanation of these settings.

SW1-1 through SW1-4 − Transmit Level (high- & low-speed modes) Switches SW1-1 through SW1-4 adjust the modem’s transmit level. Table 2-4 shows the transmit levels you can select using these switches. Table 2-4. Transmit Levels (High-Speed and Low-Speed Modes) Transmit Level 0 dBm −1 dBm −2 dBm...

Installation SW1-5 − Receiver Dynamic Range (high- & low-speed modes) 10 to −43 dBm − SW1-5 ON = OFF = +3 to −30 dBm For a low receive signal level, set SW1-5 to ON (−43 dBm ). For short distances or to select a strong receive signal, set SW1-5 to OFF. SW1-6 and SW1-7 −...

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.
Page 22
Installation SW2-5 − Soft Carrier (low-speed mode only) SW2-5 ON = Disabled OFF = Enabled SW2-5 controls the soft carrier and is valid for low-speed mode only. Setting this switch to OFF configures the modem to transmit a 900 Hz soft carrier to the remote modem after RTS is turned off.
Shelf After you set the modem’s configuration switches, you can install it in a slot within a 19- or 23-inch Telenetics or Motorola RM16M Universal Data Shelf. The modem is installed or replaced from the front of the Universal Data Shelf, without disturbing the cable connections on the back of the Shelf.

Installation Remove the front panel of the Universal Data Shelf and pick an empty slot. Hold the modem so the front panel LEDs are facing you and the edge connectors are pointing to the backplane of the Universal Data Shelf. Install the modem into the selected slot in the Universal Data Shelf (see Figure 2-3).
Connecting to a Transmission Line Figure 2-4. Modems Installed in the Rack Connecting to a Transmission Line The Universal Data Shelf has different Telco options. Your version may have 16 8-pin modular jack connectors, one for each slot in the Shelf.
The Tx line of the Shelf’s RJ-45 jack must connect to the Rx line of the other modem. For more information, refer to the Telenetics RM16M Installation and Operation Manual for the Universal Data Shelf version you have. Mass Termination Connector As an option, a 50-pin mass-termination connector can be used as the Telco connection for the modem(s).
