This manual describes the 5010-311 (4-channel) and 5010-411 (8-channel) hubs, which are used to connect micrometers to computers or PLCs. The document details the hardware components, including the front and rear panels, and explains how to connect the device using RS232 or RS485 ports via standard serial cables or USB adapters.
The guide provides comprehensive instructions on using the MODBUS communication protocol to read measurement data from up to 64 channels. It includes specific command examples for reading data from 4, 8, 12, 16, 32, 56, and 64 channels, as well as commands for clearing individual or all channels. Additionally, the manual explains how to configure internal parameters such as the device address, baud rate, and parity check settings using a specific key command. This manual is written in Chinese.
