Installation

8.4.10 LonWorks Wiring

Figure 8-23 shows typical LonWorks network wiring to the Moore 353. The network termination resistor is
supplied in the installation kit. Connections to remote devices are described in each device User's Manual, supplied
with the devices. See Section 8.4.2 for wiring guidelines.

8.4.11 Modbus Wiring

This section describes the wiring needed to connect a host device to a Moore 353's Modbus network interface.
When connected, the host can read data from and write data to a Moore 353 in a command/response format.
Most host devices communicate using RS232 while the Modbus network interface is RS485. As shown in Figure 8-
24, a 2-wire RS485 to RS232 converter is installed to perform the protocol conversion and adapt the connection
hardware. A shielded RS232 cable with either DB9 or DB25 connectors is installed between the host device and
the converter. An RS485 shielded, twisted-pair cable connects the converter to a Moore 353. Up to 32 Moore 353s
can be connected since RS485 is a multi-drop network.
Shown below are the jumper locations and identifiers for the Entrelec® Isolated Converter shown in Figure 8-24.

8.4.12 Ethernet Wiring

A sample architecture and a brief description are
presented in the Introduction section of this manual. An
RJ-45 Ethernet connector is located on the back of the
case and the optional Ethernet board is mounted on the
MPU Controller board. Ethernet cables external to the
controller must be rated Category 5 or better. Shielded
cable is highly recommended outside the panel or
cabinet, as shown at right.
