  • Page 7: About The Ms-3000 Decoder

    About the MS-3000 Decoder The MS-3000 single head decoder, companion to Microscan’s MS-520 and MS-1200 scan heads, is designed to accept high speed bar code data from a scan head, translate that data into alphanumeric characters, and send that data to a host or other terminal.

  • Page 8: About This Manual

    This manual provides complete information on setting up and installing the MS-3000 decoder. Chapter 1 provides overall step-by-step instructions for setting up and installing the MS-3000 decoder with specific “go to” references to other chapters and appendices. Chapter 2 provides instructions for configuring the MS-3000 decoder by menu.

    Warning and Caution Summary Caution: There are no user serviceable parts in the MS-3000 decoder. Opening the decoder voids the Microscan Systems warranty. Note: The MS-520 and MS-1200 scan heads are designed to be con- nected to the MS-2000 and 3000 decoders. When installed, power for the scan head is provided by the decoder.

    RS-485 Multidrop Drop 10 ft. (3 m) Front Panel Connectors The MS-3000 decoder has six I/O connectors. On the front panel (figure 1-2) there are the following two connectors: a. Trigger (Microscan or other object detector) (6-pin DIN socket) b.

  • Page 16: Figure 1-3 Trigger Connector Socket

    Pin 2 of the trigger connector is a programmable relay driver. The MS-3000 software can be programmed to set this pin high or low upon a good read, a no read, a good match, or a mismatch.

  • Page 17: Figure 1-4 Trigger Connector Wiring Diagram (Untriggered)

    To prevent voltage loss, cables between decoder and scan head should not exceed 15 feet (4.57 m) unless wire sizes exceed the minimum 26 AWG. Figure 1-5 shows a MS-3000 decoder connected to a Microscan MS-500 scan head. MS-520 Scan Head...

    You may also supply the required DC voltages yourself. A mating connector (Switchcraft #05BL5M plug) is required. Caution: Switching power supplies for Microscan equipment with a switching noise of 20 mV or greater with ±12 VDC are not recommended due to exces- sive ripple characteristics.

  • Page 19: Figure 1-8 Lan Connector

    Attach Cabling LAN Connector The Local Area Network (LAN) connector allows the MS-3000 decoder to communicate with a multidrop concentrator via a 4-wire cable (preferably shielded) with a 6-pin, 6-wire, RJ-11 type connector. Pin assignments are as shown in table 1-4.

    Communicating with and ASCII Terminal The MS-3000 decoder communicates in full duplex, terminal mode with no handshake. It also recognizes carriage returns and line feeds. The host or ASCII terminal must match the following default settings before any communication can take place: 9600 Baud Rate, Seven Data Bits, Even Parity, and One Stop Bit.

    Chapter 1 Setup and Installation Install Decoder The MS-3000 decoder can be mounted temporarily using the four rubber pads, or permanently, as follows: a. Position the decoder in a dry place. b. Before mounting, ensure that there is at least a 3 inch (76.2 mm) clear- ance at the rear and front of the decoder for the connectors and cables being used.

    (e.g., when potential differences exist between power outlet grounds) signal and chassis grounds can be isolated from each other inside the decoder by Microscan technicians. Any data line, as necessary, can be shielded. If shielding is used, isolate it from the decoder and ground only to the host earth ground.

    Interface Standards, established by the Electronic Industries Association (EIA), specify such things as the signaling voltage levels, maximum cable lengths, and number of drivers. With Microscan devices, selection of inter- face is made by pin assignment and, in the case of the host communica- tions, by software switching between RS-232 and RS-422.
