NAME
     vlan - VLAN Interface Library

DESCRIPTION
     vlan is a library to interface an IRIS workstation with video devices
     (e.g.  tape decks) via the V-LAN transmitters and receivers from
     Videomedia, Inc.  This optional hardware is required for operation of the
     library and tools described here.

   Setup
     A basic VLAN setup requires the following equipment:


        o a SGI IRIS(tm) computer with a spare RS-232 serial port;

        o a Videomedia V-LAN-T transmitter box;

        o a video tape recorder (VTR);

        o a Videomedia V-LAN-R receiver box for that make and model of VTR.

     Note that you may actually have up to 15 VTRs connected; each VTR
     requires its own V-LAN-R receiver box, but only one V-LAN-T transmitter
     is required.

     To connect up the above equipment:

        Connect the RS-232 port on the Iris workstation to the V-LAN-T. This
        uses a standard serial cable.

        Connect the V-LAN-T to the V-LAN-R. This uses a standard video cable
        with a BNC connector on both ends.

        Terminate the connection between the V-LAN-T and the V-LAN-R with a
        standard 75-ohm terminator at the V-LAN-R end. (If multiple V-LAN-R
        units are to be used, the second unit should be connected instead; the
        network should only be terminated at the last receiver box).
        Connect the V-LAN-R to the VTR. This connection depends on the make
        and model of deck.

        Connect the station video reference source to the V-LAN-T. This must
        be the same reference that is fed to the VTR.

        Connect the TC OUT (time code output) of the deck to the TC IN of the
        V-LAN-R. (This connection is not required for all types of VTR).

        Connect power to the V-LAN-T and V-LAN-R units.

     The above connections should result in an operational V-LAN network.

   Subsystems
     vlan includes the following subsystems:


     vlan.sw.dev
          This includes the V-LAN header file and library.

     vlan.sw.eoe
          This includes vlan_alive and vlan_cmd command-line control
          utilities.

     vlan.man.dev
          This includes man pages for the calls in the V-LAN library.

     vlan.man.eoe
          This includes man pages for the above.

     vlan.sw.gifts
          This includes source for vlan_alive and vlan_cmd, as well as the
          library source.

     vlan.man.relnotes
          This includes release notes for the V-LAN images.
