RS-232 Device Port Configuration

Parameter #
1246
 (SSI # F8h 04h DEh)
This parameter allows the user to select which devices to attach to the scanner, and to which port they are attached. Select the appropriate options to select the proper configuration.
The available configurations options are:
  • *0 = Aux 1 Sensormatic, and Aux 2 Scanner
  • 1 = Aux 1 Dual Cable Scale, and Aux 2 Scanner
  • 2 = Aux 1 Sensormatic, and Aux 2 Dual Cable Scale
  • 4 = Aux 1 Third Party Scale, Aux 2 Sensormatic
  • 5 = Aux 1 Sensormatic, and Aux 2 Disabled
  • 6 = Aux 1 Dual Cable Scale, and Aux 2 Disabled
  • 7 = Aux 1 Third Party Scale, and Aux 2 Disabled
  • 8 = Aux 1 Disabled, and Aux 2 Scanner
  • 9 = Aux 1 Disabled, and Aux 2 Dual Cable Scale
  • 10= Aux 1 Disabled, and Aux 2 Sensormatic
  • 11= Aux 1 Disabled, and Aux 2 Disabled
When selecting any of the device port configuration options, ensure the devices connected to the scanner correctly match the devices defined for the option. For example, if option 1 is scanned, only a dual cable scale should be connected to the Aux 1 port, and an RS-232 scanner should be connected to the Aux 2 port. Turning on the scanner with connected devices that do not match the option can result in communication failures. To ensure successful operation the proper sequence for setting this option is as follows.
  1. Power off the scanner (disconnect the power cable).
  2. Disconnect all RS-232 devices (RS-232 scanner, Sensormatic, and/or dual cable scale).
  3. Power on the scanner (reconnect the power cable).
  4. Scan the appropriate barcode option that matches the intended configuration.
  5. Power off the scanner.
  6. Connect the appropriate devices.
  7. Power on the scanner.

Changes to this parameter do not take effect until the next power cycle (power cycling does not apply to 123Scan).
Perform one of the functions below after scanning a device port parameter.
  • Cycle power to the scanner (disconnect, and re-connect scanner cable).
  • Use the scanner reset button (a button combination to reboot the scanner).
