Serial Wedge
The NCR RealScan 7837 High-Performance Scanner uses true and TTL signal
levels to wedge into an RS-232 serial network. Use 7837 serial wedge cables
only to prevent damage to the scanner. Refer to the serial interface program-
ming (pages 2-9 to 2-13) to set the baud rate and communications protocol.
To set up the serial wedge terminal ID, find the terminal ID in the Supported Ter-
minal Chart and follow the instructions on page 2-2. Set the port to which you
want the scanned data to transmit. Port 1 corresponds to P1 on the output
cable and Port 2 corresponds to P2 on the output cable. Choosing Both sends
scanned data to P1 and P2.
Default = P1.
* P1
P2
Both P1 and P2
