1. STANDARDS Meets FCC Rules Part J, Subpart 15, Class A for radiated emissions. MIU9.
2. PRODUCT OVERVIEW The MIU9.6FPD is an industrial grade Digital Fast Poll modem designed for multidropping applications over unconditioned metallic lines (eg; pilot wires). Available as single channel device (MIU9.6FPD), 2-channel device (MIU9.6FPD/D) or repeater (MIU9.6FPD/R) The MIU9.6FPD can be powered from a wide range of AC and DC power supplies, it is internally surge protected on both the power and analog lines, and it will operate in temperatures from -40 to +85 deg C. Internally, the MIU9.

5. METALLIC CONDUCTOR SPECIFICATIONS The MIU9.6FPD contains digital circuitry for connection 2 or 4-wire metallic conductors (eg; pilot wires). The MIU9.6FPD will also interface to Power Line Carrier or Microwave radio voice channel networks. The MIU9.6FPD has an RJ-11terminated connector. The following lists the MIU9.6FPD conductor interfaces Conductor Type: Conditioned or unconditioned, Bell type 3002, 2 or 4-wire, full duplex voice grade or metallic lines or better.

11. DIAGNOSTICS The following pages provide hardware techniques for diagnosing communication problems and thereby isolating the problem at the local modem, the remote modem or the interconnecting line. (a) LOCAL ANALOG LOOPBACK (Figure 2) Requires a loop back cable with a built-in circuit for line loss to simulate a typical leased line condition (See Figure 3). Connect the loop back cable to the RJ11 connector on the modem under test.
Test 3: Received Signal Level Set Dip Switch 1 OFF (TxA = -10dBm) and Dip Switch 3 OFF (RxA = -43dBm). CD will be ON. Run a test message at TxD and verify that the same message is received at RxD with no data errors. Test 4: Repeat Test 3 for various RTS/CTS delay times and with soft carrier ON and OFF.
(c) REMOTE DIGITAL LOOPBACK – 4/Wire Network (Figure 5) Configure both the local and remote modems as follows: Switch 1 = ON (TxA = 0dBm) Switch 3 = ON (RxA = -33dBm) Switch 4 = OFF (RTS/CTS = 35ms) Switch 5 = ON (RTS/CTS = 35ms) Switch 6 = ON (Constant Carrier mode). Switch 7 = OFF (4-Wire) Switch 8 = ON (Line Termination = 600 ohms) Switch 9 = ON (Soft Carrier Turn Off = ON) Connect TxD to RxD at the remote modem.
(d) LINE DIAGNOSTICS (i) Typical modem configuration for 4-wire Point-to-Point system… Switch 1 = ON (TxA = 0dBm) Switch 3 = ON (RxA = -33dBm) Switch 4 = OFF (RTS/CTS = 1ms) Switch 5 = OFF (RTS/CTS = 1ms) Switch 6 = ON (Constant Carrier mode).
