Installing the PW-6000 Input Module
Power
PW-6000 Input Module Installation Guide, Document 800-01952, Revision B 7
Power
The Input Board accepts 12VDC with an operating range of 10 to 16VDC and
consumes 250mA of current. Locate power source as close to this board as possible.
Connect power with minimum of 18AWG wire.
Note: POLARITY for 12VDC power is important. Make sure the +12 VDC is connected to
the terminal labeled +12V and the return is connected to the terminal labeled GND.
Communications
The Input Board communicates to the host controller through an RS-485 interface.The
interface allows for multi-drop communication of up to 4,000 feet (1,200 m) total per
port. Use two twisted pair (minimum 24AWG) with shield for communication
(Belden 9842 or equiv.). The default speed of this port is 38.4Kbps but it can be
downgraded to 19.2Kbps or 9.6Kbps if the line conditions or receiving equipment
require it (see Table 1 on page 2 for jumper settings and Table 2 on page 3 for DIP
switch settings).
For wiring to an RS-485 port:
1. TR+ is the plus side of the transmit and receive differential signal.
2. TR- is the negative side of the transmit and receive differential signal.
3. GND is the signal ground. The wiring for this signal is required and
NOT
optional. This signal must NOT be connected to chassis GND.
4. Use 24 AWG low capacitance, two twisted-pair, shielded cable (Belden 9842
or equiv.).
Note: For RS-485 Communication Connections, twist the blue pair together
and use as the common; use the orange pair as your data pair, observing
polarity. Connect the external drain shield to the appropriate earth ground on
one end.
5. When daisy-chaining RS-485 ports together, connect the TR+ wires from the
upstream and downstream boards to the TR+ terminal. Likewise, connect the
TR- wires from the upstream and downstream boards to the TR- terminal.
