Page 5 Chapter 1 Introduction ongratulations for purchasing the finest industrial-grade fast- poll rack-mount modem available. The Telenetics DSP9612RM (Flash Poll) modem is a 9600/4800/0-1800 bps rack-mount modem designed for 4-wire, full- duplex or 2-wire, half-duplex operation over a voice-band leased line.
Introduction Page 6 Features Though functionally similar to comm ercial modems , the DSP9612RM provides the following unique features that make it well suited for utility and industrial applications. c Requires only one rack slot in a Telenetics or a Motorola/UDS RM16M Universal Data Shelf.
Applications Page 7 Applications The DSP9612RM modem is designed for point-to-point and m ultipoint data communications. Figure 1-1 shows a typical m ultipoint configuration. Figure 1-1. Netw ork of Multipoint Configuration There are a number of factors that can affect the network ’ s and modem ’ s operation and perform ance.

Installation Page 12 Installation Summary The modem installation involves the following steps: 1. Configuring the modem. See the section below. 2. Connecting to a transmission line.
Configuring the Modem Page 13 Table 2-1. Modem Sw itch Settings for High-Speed Mode Switch Settings Switches ON OFF (Default) SW 1-1 − 1-4: Transmit Level (page 14 ) (see Table 2-2 on page 14) SW 1-.
Installation Page 14 SW1-1 through SW1-4 − Transmit Level (high- & low-speed modes) Switches SW1-1 through SW1-4 adjust the modem ’ s transm it level.
Configuring the Modem Page 15 SW1-5 − Receiver Dynamic Range (high- & low-speed modes) SW1-5 ON = − 10 to − 43 dBm 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.
Installation Page 16 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) m ode or high-speed (Fast Poll) mode. As a result, the SW2-1 setting you choose determines the switch definitions for the other switches.
Configuring the Modem 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.
Installation Page 18 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) m ode. This mode is enabled when switch SW2-1 is set to ON. Following this table is an explanation of these settings.
Configuring the Modem Page 19 SW1-1 through SW1-4 − Transmit Level (high- & low-speed modes) Switches SW1-1 through SW1-4 adjust the modem ’ s transm it level. Table 2-4 shows the transmit levels you can select using these switches. Table 2-4.
Installation Page 20 SW1-5 − Receiver Dynamic Range (high- & low-speed modes) SW1-5 ON = − 10 to − 43 dBm 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.
Configuring the Modem Page 21 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) m ode or high-speed (Fast Poll) mode. As a result, the SW2-1 setting you choose determines the switch definitions for the other switches.
Installation Page 22 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 transm it a 900 Hz soft carrier to the remote modem after RTS is turned off.
Installing the Modem in the Universal Data Shelf Page 23 In switched-carrier mode (SW2-8 set to OFF), the RTS/CTS delay is 23 ms. SW 2-9 − RX Termination (high- & low-speed modes) SW2-9 ON = Disable Rx Termination OFF = Enable Rx termination SW2-9 selects whether RX termination is enabled for a modem .
Installation Page 24 3. Remove the front panel of the Universal Data Shelf and pick an empty slot. 4. 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. 5. Install the modem into the selected slot in the Universal Data Shelf (see Figure 2-3).
Connecting to a Transmission Line Page 25 Figure 2-4. Modems Installed in the Rack Connecting to a T ransmission 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.
Installation Page 26 c 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.
LEDs Page 27 LEDs The front panel of the modem provides the LEDs shown in Table 2-7. Table 2-7. Modem LEDs LED Color Description Power Green Power RTS Yellow Request To Send CTS Yellow Clear To Send T.
Installation Page 28 Loopback Control Switch The front panel of the modem has a push button for initiating the following loopback diagnostic tests: c Local analog loopback started by pressing the button one time. c Local digital loopback started by pressing the button two times.
