INSTRUCTION MANUAL

2.4.3 Datalink Communication

Datalink is an interrogator/responder serial interface capable of supporting 32 instruments on a single

network. It uses an RS485 physical interface. The Datalink wiring diagram for this instrument is provided as

Figure 2-5. Complete coverage of the Datalink is provided in Instruction Bulletin 53SU5000.

2.5 Factory Set Calibration

Each unit contains individual factory set entries that calibrate the four analog inputs (ANI0 through ANI3) and

analog output (ANO0). There is a calibration sheet supplied with each instrument that should be retained for

future reference when the installation is completed. Reference Section 5.3 for additional information.

2.6 Grounding

Installations are expected to have access to an independent, high quality, noise-free point of earth reference.

The system should be connected by a dedicated, low resistance (less than one ohm) lead wire directly to the

installation’s point of earth reference. This ground reference is referred to as the Instrumentation Ground. If

an instrumentation ground reference does not exist in the installation, an earth ground electrode should be

established with an independent grounding rod or ground grid mesh.
