Installing The Realscan 7892-0200 (Wedge) - NCR RealScan 7892 User Manual

Installing the RealScan 7892-0200 (Wedge)

The RealScan 7982-0200 (Wedge) option permits the RealScan 7892 to
be connected to the host terminal through a keyboard connector. Scan
data is input into the keyboard port. When connected in this
configuration the RealScan 7892 cannot receive commands from the
host terminal.
Note: Unlike the RealScan 7892-0100 there is only a single transmit
message buffer in the RealScan 7892-0200wedge use. The transmission
of the data is significantly longer than other communication protocols
and can be quite slow if a long intercharacter delay is required.
Note: The Keyboard Wedge cable connects both the scanner and the
keyboard to the host terminal through the keyboard port. This cable
has two PS/2 connectors. If the Host terminal system has an AT
keyboard connector, two adapters are required: an AT to PS/2 and a
PS/2 to AT. These adapters are available locally at most computer
stores.
Belkin F2N017 – AT to PS/2
Belkin F2N018 – PS/2 to AT
