preferred for a permanent device like a bar code scanner in POS business.
To access the internal connection you must remove the keyboard. To
do this first unlock the front door lock and then remove the two mounting
screws from the underneath of the chassis located just behind the front edge of
the terminal. Once these screws have been removed it is possible to lift the
front edge of the keyboard housing and then rotate the keyboard “up and back”.
This then exposes the keyboard controller on the underside of the keyboard.
Connector for the external KB port is normally inserted into socket on
controller board of programmable keyboard. To add an internally connected
device, remove this cable from the controller board and insert the new device
between them. Match the top edge of the programmable keyboard with rear
cabinet of main unit and close it to the bottom chassis. Before closing it, the
cables must be fixed to the bottom chassis with a cable tie and a piece of cable
cover at side of bottom chassis must be taken away. Mount back the two
screws from bottom side then the installation for internally connected KB
wedge device is done.
We strongly advise users to consult with their dealers to have an
authorized technician for such installation.
PRINTER
Assemble the printer following the instructions supplied with the
printer.
Remove the battery cover as in UPS battery section. The user may
find the UPS battery lying in the battery compartment if this option is ordered.
Connect the printer cable through the opening on the wall toward the rear room
of the cabinet to the connector marked “LPT” (if the printer is a parallel
printer). Or connect the cable to a proper “COM” port (COM 1 through COM
4) according to the definition on the application program (if the printer is a
serial printer). The 24 VDC power cable (CCBLA-146A to be separately
purchased) should be inserted to the 24 VDC connector in the rear room if the
printer is to use this power supply from the terminal. These cables should pass
through the opening on the wall where the UPS battery cover joins the case.
Replace the battery cover and connect the signal and power cables to the
appropriate connectors on the underside of the printer. Finally place the printer
on the printer platform of the terminal.
