Configuring Using Programming Bar Codes

To configure the NCR 7895 scanner using programming bar codes, follow these steps:

1. Using an RS‑232 communication cable, connect the NCR 7895 scanner to a computer or POS terminal. The scanner produces three incrementing beeps.
2. Scan the following bar code to set RS‑232 Host Type to NCR Variant interface and activate the RS‑232 driver.

   

3. Set the following NCR Variant settings by scanning their corresponding bar codes.

   Parameter	Description
   NCR Use Prefix	Uses prefix for all communications. By default, this parameter is enabled. Enable—for customers using prefix. Disable—for customers not using prefix.
   NCR Prefix	Determines the Prefix Character used for all communications. By default, this parameter is set to 1002 (prefix 02, STX). Note If the NCR Use Prefix parameter is disabled, the NCR Prefix parameter is not required.
   NCR Use BCC	Uses of the Block Check Character (after the Terminator byte) for all communications. Set this parameter based on the NCR Interface used. By default, this parameter is enabled. Enable—for Scanner/Scale interface. Disable—for Scanner Only interface.
   NCR Interface	Sets the NCR specific interface to be used for all communications. By default, this parameter is set to Follow System. Follow System—auto-detects the system interface used. Scanner Only—for NCR 7895 scanner‑only units. Scanner/Scale—for NCR 7895 scanner/scale units.

   Refer to the following sections for the RS‑232 bar codes:

   • NCR Use Prefix (Parameter #1238)
   • NCR Use Block Check Character (BCC) (Parameter #1239)
   • NCR Interface (Parameter #1240)
4. Reboot the NCR 7895 scanner to re-enumerate the device.
5. Launch any serial application and test scanner functions such as scanning bar codes, sending commands, and others.
