This document is the operation manual for MC510 Gateway, which introduces the installation precautions, power supply, gateway port, wiring requirements, air conditioning application examples, gateway settings, and PC simulation testing.
This manual describes the MC510 Gateway, which bridges McQuay MDS HVAC control systems with ModBus‑based building automation networks. It explains the gateway’s function, LED indicators, power requirements, port configuration, and wiring guidelines.
The document also includes step‑by‑step instructions for connecting the gateway to PCs, setting up ModBus parameters, and using the provided configuration software. Application examples show how the gateway interfaces with MDS units and MC501_B converters, and an appendix lists the ModBus register map. This manual is written in Chinese.
| Power supply range | 100 Vac – 240 Vac, 50/60 Hz |
|---|---|
| Fuse rating | 250 mA |
| Maximum connected units | 8 MDS units or MC501_B converters |
| Maximum cable length per segment | ≤ 1000 m |
| Shielded twisted‑pair conductor area | ≥ 0.5 mm² (20 AWG) |
It operates from an AC supply of 100 Vac to 240 Vac at 50 or 60 Hz.
A single MC510 gateway can connect up to eight MDS units or MC501_B converters.
The default gateway ID starts at 1 and can be changed in the “Remark” field.
The gateway uses the ModBus RTU format based on the Modicon ModBus Protocol Reference Guide (March 1992).
