The display cable comes with a DB9 already jumpered to plug into a
serial port.  For an Immage or Javelin, use the following adapters:

Immage        TPD
RJ45        DB9
—-        —
  2 — GRD —  5
  3 — RXD —  2
  5 — TXD —  3
  4 — DTR
        |  (jumper)
  6 — DSR

Software

TPD.EXE is a utility that reads Check Amount from VARIABLE.TXT,formats the output to include a checksum calculation, and transmits it out a COM port.  The default port is COM2 but that can be changed with a command line switch /COM=x where x is the port number.  Style it in as follows:

  1. Make a shell with the Command Line set to TPD.  Add /COM=x if needed.  Press Alt-S to select store variables and Alt-P to preserve screen.
  2. Add a Shell to TPD command immediately after the check is retrieved at the recall station to display the total.
  3. Add a Shell to TPD command immediately after the close check command to transmit a clear to the display. Note:  If the Check Amount is zero, the utility transmits a clear to the TPD instead of the amount.  The display has a built
      in 30 second delay prior to actually clearing.
  4. Depending on the order flow, additional Shell to statements may need to be added to assure that the proper total remains on the display.
  5. Make sure that TPD.EXE is added to the Tools directory.
