24 Pelco Manual C690M-E (11/04)
CONNECTING POS TERMINALS AND ATMs
The DX2000 supports data input from up to 16 POS terminals or ATMs. The DVR provides
options for connecting these devices using DX2000 data adapters. These optional adapters let
you connect to RS-232 serial interfaces and optically isolate each device from the DX2000.
In addition, the optional DX2000DH Data Hub provides a local connection for up to seven ATM
or POS devices and delivers the transaction data to the DX2000 over a single cable. Up to four
data hubs can be daisy chained for connecting with devices up to several miles away.
The DX2000 data ports can also be connected directly to the Pelco PIM (personality interface
module), which permits connection to POS terminals that do not have an RS-232 interface.
Refer to Figure 3. The POS terminal/ATM are numbered 1 (top) through 4 (bottom).
Each port can be configured differently, allowing a number of possible combinations. The
system can support up to 16 data devices. Multiple network devices can be connected through
a single port while devices with dedicated output ports can be connected directly to the four
data ports or to the DX2000DH Data Hub.
The ports are defined as follows:
Port 1: SUPPORTED CONNECTIONS
POS Device: COMM Port (Asynchronous) or Pelco PIM
ATM: SNA (SLDC)
Port 2: SUPPORTED CONNECTIONS
POS Device: COMM Port (Asynchronous) or Pelco PIM
ATM: SLDC (SNA)
Port 3: SUPPORTED CONNECTIONS
POS Device: COMM Port (Asynchronous), Pelco PIM, or DX2000 Data Hub
(Supports Asynchronous RS-422 through Signal Converter)
Port 4: SUPPORTED CONNECTIONS
POS Device: COMM Port (Asynchronous), Pelco PIM, or DX2000 Data Hub
(Supports Asynchronous RS-422 through Signal Converter)
