  • Page 45: Standard Units - Led Description

    If a multi-drop unit is operating in Local Unit Configuration mode, the function of the remaining LEDs is indicated by the blue TERMINAL labels (TX, RX, RTS, CTS, DSR, DCD, and DTR). These LEDs reflect the state of the active terminal port's EIA-232 lines. If one of these LEDs is illuminated, this indicates that positive voltage is detected on the respective signal.

  • Page 46: Select Switch

    If a standard unit is operating in Local mode or MUX mode, the function of the LEDs is indicated by the white COMPOSITE labels (TX, RX, DSR, CTS, and DCD). The LEDs reflect the state of the EIA-232 line for the composite port.

  • Page 47: Data Flow Control

    Once the SELECT switch is released, the Telplex will send a power-up status message as discussed in Section 4.1.2.4. Send the Escape Code Sequence to access System/Local mode.

    The procedure for configuring multi-drop units and standard units is basically the same. However, the resulting configuration menus are different in appearance. These differences will be specified in the following sections. The menus shown will be for the TX104 which are similar for the TX102 and TX108.
  • Page 51 To access Local or Remote Unit Configuration mode for either type of Telplex, use the following procedure: Connect a dumb terminal or a computer emulating a dumb terminal to the desired terminal port (factory default is Port 1). Make sure your terminal device is configured to operate at the same serial parameters as the terminal port on the Telplex.

  • Page 52: Main Configuration Menu

    Telplex will first prompt you to enter the desired unit number and module number of the remote Telplex. The module number will be "1" for a remote TX102, TX104, TX108, or TX4. The module number will be 1 to 8 for a remote TX28 or 1 to 16 for a remote TX60.

  • Page 94 OTHER BAYTECH PRODUCTS Print Master 700 Series printer controllers are made in several different configurations satisfying various interface requirements. Each unit allows computers to share, select and/or contend for printers easily and economically, without switching cables. The internal buffering system allows simultaneous, high-speed input from all connected computers and output to all printers.
  • Page 95 The PS-4A has four parallel ports, the PS-4C will has four high speed serial ports, and the PS-4E has two parallel and two high speed serial ports. The BayTech LaserShare Network PS-MIO is a network print server card which installs into the MIO slot of the HP LaserJet Series IIISi, Series 4, and Series 4Si laser printers.
  • Page 96 Tran-x PS-02 connects to your PC's parallel port. Tran-x SP-01 connects to the Centronics connector of a parallel printer. Tran-x SP-02 connects to the DB-25 parallel port of the BayTech 700 Series Print Master, 800 Series Print Master II, or Model 24/24SII DES peripheral sharing units.

Telplex Models TX102, TX104 and TX108 are asynchronous statistical multiplexers which multiplex and demultiplex two, four, or eight communications channels over a single channel. This single channel is typically a telephone line or cable.
  • Page 98 NOTE: All ports on the 500 Series are standard with EIA -232 ports. EIA-422 and Current Loop ports are optionally available. If you have questions concerning any of BayTech's products, please feel free to call a BayTech Applications Engineer at either (800)523-2702 or...
