  • Page 8: Introduction

    TWIN MUX REPEATER MODULES 2. Introduction The Twin Mux Repeater Module is a hot-swappable 8-port multiplexor for the Power Cage 500 Solution (RM601A) for use in the IBM S/3X or AS/400 ® ® environment. The Twin Mux Repeater Module lets you combine eight host ports over one fiber, UTP, or STP cable pair for more cost-effective cabling installations.
  • Page 9 TWIN MUX REPEATER MODULES Features • Hot-swappable 8-port multiplexor. • Same unit can be used on controller or workstation side (switch-selectable). • Doubles the distance between each workstation and the controller. • True repeater technology; bi-directional. • Data amplitude, timing and duty cycle corrected to remove jitter. •...
  • Page 10 TWIN MUX REPEATER MODULES • Diagnostic Parity Error LED on each controller (Ctrl), workstation (Term) and link ports. • Intelligent Line Sync/Polarity LEDs will light only for a true IBM System 3X or AS/400 signal received in the correct polarity. •...

    TWIN MUX REPEATER MODULES 3. Installation 3.1 Basic Installation Follow the steps below to properly install the Twin Mux Repeater Module. NOTE The RJ-45 connectors of the Twin Mux Repeater Module are designed for use with (part number IC065) 3X or AS/400 baluns. If you use other balun, you might have to reverse the polarity of the Twin Mux Repeater Module via the polarity DIP switch.

  • Page 13: Pin Configuration

    TWIN MUX REPEATER MODULES 3.1.1 P ONFIGURATION You can change the pin configuration via the jumper switches on the printed circuit board. The pin configuration of each RJ-45 connector is factory-set to RJ-45 pins 4 and 5. In order to set the pin configuration to pins 1 and 2, move the jumper located beside each RJ-45 connector to the “1 and 2”...

  • Page 17: Verifying

    TWIN MUX REPEATER MODULES Avoid using 50- and 100-pair cable when trying to achieve optimum performance, since it may add to cross-talk and capacitance problems. Never use flat cable (cable that is not twisted, sometimes referred to as silver satin), not even for patching short runs. Flat cable will act as an antenna and pick up nearby radio-frequency or electromagnetic radiation interference that cannot be removed.

  • Page 25 TWIN MUX REPEATER MODULES 6. Verify that the balun pin-outs match that of the Twin Mux Repeater Module. Both the Twin Mux Repeater Module and the IC065 baluns should have an ohm-meter reading of less than 1 ohm across their active pins.
  • Page 26 TWIN MUX REPEATER MODULES NOTE Different terminals terminate in different ways. Some have termination switches, while others terminate via a self-terminating Twinax “T” or “Y” splitter cable. Improper termination settings can cause intermittent problems. 2. Verify that the pair of wires used are in fact twisted with each other and not with other wires (i.e., check for split pairs).
  • Page 27 TWIN MUX REPEATER MODULES Technical Support Information When contacting Technical Support, please have the following information ready: 1. Unit type (fiber or copper version with pin-out information). 2. Balun type used. 3. Unit serial number. 4. Environment lay-out. Include controller and workstations used (with model numbers), estimated cable lengths (between what equipment) and type of cable used (UTP, STP, Flat, 25-pair, 50-pair or 100-pair).
