9300 Series User’s Guide

 

 

Install a ¼ Watt termination resistor (RT) between the (+) and (-) terminals of the device at each end point of a straight-line bus. The resistor should match the nominal impedance of the RS-485 cable (typically 120 ohms – consult the manufacturer’s documentation for the cable’s impedance value).

CAUTION

Do not connect ground to the shield at both ends of a segment. Doing so allows ground loop currents to flow in the shield, passing noise into the communications cable.

RS-485 Connection Methods to Avoid

Any Device connection that causes a branch in the main RS-485 bus should be avoided. This includes star and tee (T) methods. These wiring methods cause signal reflections that may cause interference. At any connection point on the RS-485 bus, no more than two cables should be connected. This includes connection points on instruments, converters, and terminal strips. Following this guideline ensures that both star and tee connections are avoided.

Avoid

3-way “Star” connection point

Avoid

3-way “T” connection point

Optical Port Connections

Refer to the “Hardware Reference” chapter for the optical port specifications.

The optical (infrared) port on the meter’s front panel is compatible with an ANSI C12.13 Type II magnetic optical communications coupler. The optical magnetic coupler is purchased separately. Contact your supplier for a list of recommended opto-couplers.

The optical port can communicate real-time measurements to a laptop or similar device via ION, Modbus RTU, or DNP 3.0 (9330 and 9350). The port can also be used for infrared energy pulsing.
