Page 5 Chapter 1 Introduction ongratulations for purchasing the fi nest industrial-grade fast- poll modem available. The Telenetics DSP9612 (Flash Pol l) modem is a 9600/4800/0- 1800 bps modem designed for 4-wire, full-duplex or 2-wi re, half- duplex operation over a voice-band leased li ne or private line.
Introduction Page 6 Features The DSP9612 modem is specifically designed for harsh environment s found in utility substations and industrial facilities. Though functionally sim ilar t o comme rcial modem s, the DSP9612 provides the following uniqu e features that make it well suited for utility and industrial appli cations.
Applications Page 7 Applications The DSP9612 modem is designed fo r point-to-point and multipoint data comm unications. Figure 1-1 shows a t ypical m ultipoint configuration. Figure 1-1. Network of Multipoint Configuration There are a number of factors that can affect the network’s and modem ’s operation and performance.

Page 9 Chapter 2 Installation his chapter describes how to install the modem . Unpacking Y our Hardware Your package should include: At least one of the followi ng DSP9612 modem s: − Model DSP96.
Installation Page 10 A power supply that provides eit her: − 85 to 265 Volts AC, 50 to 60 Hz, si ngle phase or 85 to 400 VDC (if you have the m odel DSP9612FP modem ), or − 10 to 53 Volts DC (if y ou have the model DSP9612-LV modem ) Hardware Overview Back View Figures 2-1 and 2-2 show the back view of the two DSP9612 m odem models.
Hardware Overview Page 11 Figure 2-2. Back View of Model DSP9612-LV Modem Front View The Model DSP9612FP and Model 9612-LV m odems have identi cal front panels. Figure 2-3 shows the front view of t he modem . Starting from the left side, this view shows: A set of nine LEDs.
Installation Page 12 Installation Summary The modem installation i nvolves the following steps: 1. Finding a suitable l ocation for the modem . See the section below. 2. Configuring the m odem. See page 13. 3. Connecting to a transm ission line. See page 25.
Configuring the Modem Page 13 Configuring the Modem You configure the modem using the three sets of DIP swit ches on the bottom of the m odem. , IMPORTANT It is important to follow the three steps d escribed below, in the order shown, to ensure that you confi gure your modem properly using the m odem DIP swi tches: 1.
Installation Page 14 SW1 DIP Switch Settings SW1 is an 8-position DIP switch. Tabl e 2-1 shows the modem switch settings for DIP switch SW1. A descripti on of the SW1 switch settings follows the table. Note: SW1 settings apply for both high-speed fast -poll and low- speed (FSK) modes Table 2-1.
Configuring the Modem Page 15 SW1-1 through SW1-4 − Transmit Level Switches SW1-1 through SW1-4 adjust the modem ’s transmit level. Table 2-2 shows the transmit levels you can select usi ng these switches.
Installation Page 16 SW1-5 − Receiver Dynamic Range 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 ).
Configuring the Modem Page 17 SW2 DIP Switch Settings SW2 is an 8-position DIP switch. Tabl e 2-3 shows the modem switch settings for DIP switch SW2. A descripti on of the SW2 switch settings follows the table. Table 2-3. Modem Switch Settings for DIP Sw itch SW2 Switch Settings Switches ON OFF (Default) SW2-1: FSK Mode (page 18) V.
Installation Page 18 SW2-1 FSK Mode SW2-1 ON = ITU-T V.23 mode OFF = Bell 202 m ode The modem has two FSK modes: Bell 202, which support s data rates from 0 to 1800 bps ITU-T V.23, which supports data rat es from 0 to 1200 bps SW2-1 conf igures the modem for either of these FSK modes.
Configuring the Modem Page 19 wire, half-duplex m ode (SW3-7 ON), the modem squelc hes the receiver after RTS is turned off to prevent far-end echoes from causing data errors.
Installation Page 20 When the modem i s configured for V.23 operation (SW2-1 ON), the RTS-CTS delay i s 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 vali d when Bell 202 m ode is active (SW2-1 OFF).
Configuring the Modem Page 21 SW3 DIP Switch Settings SW3 is a 10-position DIP switch. Tabl e 2-5 shows the modem switch settings for DIP switch SW3. A descripti on of the SW3 switch settings follows the table.
Installation Page 22 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 m ode, which supports data rat es of 4800 and 9600 bps.
Configuring the Modem Page 23 SW3-2 − Data Rate (Fas t-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), setti ng SW3-2 ON selects 4800 bps, while setting SW3-2 OFF selects 9600 bps.
Installation Page 24 SW3-5 − Transmitter Termination SW3-5 ON = Switched by RTS OFF = 600 Ω SW3-5 is used for multi-point configuration n etworks. When multiple modems are connected on the same metallic circuit: The transmitter termination should be of high im pedance if the modem is not transmitting.
Configuring the Modem Page 25 SW3-8 − Carrier Control SW3-8 ON = Constant OFF = Switched SW3-8 selects either constant or switc hed carrier. Constant carrier allows DTEs, such as asynchronous dumb t erminals or RT Us, to operate with m odems, without the input RTS signal .
Installation Page 26 Connecting to a T r ansmission Line The modem has a transm ission line inte rface that can be configured for 2- or 4-wire, analog connection, where one pair is used t o transmit dat a (Tx and Tx) and one pair is used to receive data (Rx and Rx).
Connecting to a Voltage Source Page 27 Figure 2-4. Transmission L ine Interface Connecting to a V oltage Source The back panel of the modem pr ovides the power interface.
