5 Wiring
This section describes the wiring required to connect external devices with serial interfaces and the
power supply.
DANGER – Serious damage to health / risk to life . Do not begin wiring unless the area
is known to be non-hazardous.
5.1 Wire for serial communication
The analyzer’s Serial Ports 1 and 2 (J8 and J10) support RS-232, RS-422 or RS-485 communication.
They support connection to devices with serial interfaces including:
 Remote communication equipment such as a radio
 Flow computers or remote controllers (for flow measurement scenarios requiring live analysis)
Serial port configuration depends on the external device being connected. Note that the serial ports
can also provide power to the attached device (pins 1 or 3) depending on the power requirement of
the device. Determine the device’s serial interface type and requirements and configure the serial
ports accordingly. Wiring for communication devices is specific to the communication transceiver,
therefore only general information is given here. Table 5-1 shows serial port pinouts and termination
settings.

5.2 Wire for power and grounding
This section describes the power supply requirements, power considerations, the wiring of the power
terminal on the analyzer’s termination board, and grounding. Carefully review requirements and
considerations before wiring the analyzer and additional devices (if any).
Figure 5-1 shows an example of an analyzer’s installation and wiring. This scenario includes an
independent enclosure containing a power supply and a radio system for remote communication.
