Data Communication

The Data Communication option allows almost all functions that can be performed at the Analyzer to be performed remotely. Data available remotely is listed below.

Data communication can be RS232 full duplex or RS485 half duplex (2-Wire). RS232 connections are wired as DCE for direct connection to a personal computer. Trace Technology SmartTalk software or any Modbus communication software can be used to communicate with the Analyzer using Modbus RTU.

• Communication can be at 9600, 19200, 38400 and 115200 bits per second.
• Byte structure can be O81, O71, E81, E71, N82, N72, N81.
