Overview

Accura 2550GW[M] module collects data from peripheral devices supporting RS-485 communication and transmits the collected data to Accura 2500 device

With one or four^*RS-485 communication ports, Accura 2550GW[M] can collect up to 60 data items from devices using different communication protocols

It is possible to set a timeout period for a response packet.

It is possible to set a delay time between the completion of data collection and the start of the next data collection.

* Accura 2550GW module supports one port, and Accura 2550GWM module supports four ports.

1. Communication cables for communication with Accura 2550GW[M] are not provided. It is recommended to use shielded Ethernet cables such as Cat. 5e 24 AWG FTP cables.
2. If you want to ground the shielded wire, you can either connect it directly to the grounding terminal or to the SG terminal.
The SG terminals are internally connected to the grounding terminal through the Accura 2500M.
3. Certification for Accura 2550GWM is pending.
