Connecting POS (Point of Sales)
AVerMedia
®
AVerDVR can be integrated with POS system equipment. Connecting the POS
equipment to AVerMedia
®
AVerDVR system thru RS232 connection, enables you to view,
record and keep track of the items that were sold. You may also select the camera on where to
display all the data. To connect, locate the RS232 port of the POS equipment and PC. Use an
RS232 cable (not supplied) to make the connection.
