                        OMNI 3200 SERIAL TAP

To install the 3200 SERIAL TAP, simply connect the RJ45 cable to the serial
port of the 3200, and plug the DCE (CID, Precidia etc.) cable into the
socket at the center of the white cover plate on the 3200 SERIAL TAP:

There are three monitoring connectors on the 3200 SERIAL TAP, which
are labeled:

  PC1/3200 = Monitored output from the  3200 (DTE) only.
  TAP/DUAL = Monitored output from both 3200 (DTE) and DCE
  PC2/DCE  = Monitored output from the  DCE only.

All three connectors are standard DB-9 format. I have provided two
DB-9 Male to DB-9 Female extension cables and 2 DB-9 to DB-25 adapters
which should allow you to connect to virtually any PC or datascope
(At most 2 connections are used at one time).

To monitor the 3200 serial port using a RS-232 DATASCOPE:
---------------------------------------------------------
 - Connect the DataScope directly to the TAP/DUAL connector.
   Use a DB-9 to DB-25 adapter if required - NOTE: I have modified one
   of the adapters with shorter screws to allow it to plug directly into
   the TAP. This adapter is marked with a black DOT.
 - Set DataScope to 9600 Bps, 7-Bits, Even Parity, and monitor/
   record the data as per the DataScope operating procedure.

To monitor the 3200 serial port using my DLM program on a PC:
-------------------------------------------------------------
 - Connect the PC's COM1 port to the PC1/3200 connector using a
   provided extension cable (and a DB-9 to DB-25 adapter if required)
 - Connect the PC's COM2 port to the PC2/DCE connector using a
   provided extension cable (and a DB-9 to DB-25 adapter if required)
 - Execute the DLM program
   - Go to "Serial Port Parameters" menu
     - Select "Configure DTE and DCE"
       - Select "Baudrate" and pick 9600 BPS (Press ENTER)
       - Select "Data Bits" and pick "7" (Press ENTER)
       - Select "Parity" and pick "Even" (Press ENTER)
     - Press ESC to back out of the menus and return to the main one
   - Select "Begin Data Capture"
   - Run your transaction(s)
   - Select "Review Captured Data" to look at what happened in detail
     (See included DLM.TXT file) for display details
   - Press ESC to return to main menu
   - Use "Clear capture buffer" to start fresh, otherwise each capture
     session will "append" to the previous one.
   - If you capture something you want to send to me:
     - Select "Disk transfer functions"
       - Select "Save Data Image"
       - Pick a new filename if you wish, or just use the default IMAGE.DLI
       - Press ENTER to save image into file
       - Use ESC to back out of menus
   - Select "Exit to DOS" to terminate the program.
   ** See DLM.TXT documentation for more information on using DLM.
   NOTE: My DLM program has an "issue" with recording the DCD signal, so
         the PC2/DCE connector provides the DCD output as DSR which poses
         no problems to DLM. Since DSR is not used on the 3200 interface,
         nothing is lost in doing this, simply note that DLM's DSR indicator
         is actually tracking the state of DCD at the 3200.


Detailed Connector Descriptions:
--------------------------------

TAP/DUAL:
  This port connects to ALL signals which are defined on the 3200
  serial port (except for clocks used in sync. interfaces):
    3200 (RJ-45)         TAP (DB-9)         Name
        1                   n.c.            Transmit Data Clock
        2                   n.c.            No connection
        3                    1              Data Carrier Detect
        4                   n.c.            No connection
        5                    5              Ground
        6                    2              Receive Data
        7                    3              Transmit Data
        8                    8              Clear To Send
        9                    7              Request To Send
        10                  n.c.            Receive Data Clock
    This port should be used to monitor the 3200 serial port with a
    device intended to read BOTH DTE and DCE data from a single connector
    such as a DATASCOPE. You should NOT connect a PC or any other device
    which drives either the DTE or DCE side of the RS-232 line to this
    port, as doing so will cause a conflict resulting from two devices
    attempting to drive one signal.

PC1/3200:
  This port connects to only the signals originating from the 3200 (DTE),
  and also translates them into DCE signals which can be read by a direct
  cable connection to a PC running my DLM software:
        3200 (RJ-45)                 PC1 (DB-9)
         5 - Ground                   5 - Ground
         7 - Transmit Data            2 - Receive Data
         9 - Request To Send          8 - Clear To Send
    + All other 3200 signals are "no connect" on this connector
    This port must be connected ONLY to a DTE device such as a PC.
    Connecting this port to a DCE device will cause a conflict as both
    this port and the 3200 would be attempting to drive these signals.

PC2/DCE:
  This port connects to only the signals originating from the DCE,
  allowing them to be read by a direct cable connection to a PC running
  my DLM software:
        3200 (RJ-45)                PC2 (DB-9)
         3 - Data Carrier Detect     6 - Data Set Ready (**)
         5 - Ground                  5 - Ground
         6 - Receive Data            2 - Receive Data
         8 - Clear To Send           8 - Clear To Send
    + All other 3200 signals are "no connect" on this connector
    (**) NOTE: My DLM program has an "issue" with recording the DCD signal,
         so this connector provides the DCD output as DSR which poses no
         problems to DLM. Since DSR is not used on the 3200 interface,
         nothing is lost in doing this, simply note that DLM's DSR indicator
         is actually tracking the state of DCD at the 3200.
