3.12 Interfacing POS Devices
Your DVR can receive POS data from nearly any serial ASCII data source including
registers at the point of sale (POS), ATMs, alarm panel, access control systems,
intelligent safes, weight scales, and other such sources. For the sake of simplicity,
we will refer to all such sources as POS data. Your DVR includes two serial ports
for receiving POS data. If you are using network data capture please refer to Part
II Software for information about the network capture setup.
Direct Serial POS Data Connection
For only one or two POS data sources,
use the direct serial connection
method. Here a pigtail connector is
inserted at the back of the printer
with the printer’s RX and GND
wires paralleled off. A suitable
two-wire data cable connects
this pigtail to another pigtail and
is used at the DVR’s POS port.
Pigtail accessory cables are avail-
able from Image Vault for various
printer styles; sold separately.
Functionally this acts like one
cable as illustrated.
