RVG200 Comms Modbus
I hope you can help me with this issue. I need communicate 4 ControlMaster CM30 with RVG200 trough Modbus RS485, the videorecorder like master (host), but i can't communicate them.
The instruction manual refer that i need a gateway to convert RS485 to TCP.
How can communicate both instruments without Host Computer, is possible directly?.
Thanks in advance for your help.
You can communicate over either Modbus TCP or RS485 modbus on both instrument types. The RVG200 has Ethernet fitted as standard. If ethernet is fitted to the ControlMaster's then you can communicate directly via TCP modbus. If they have RS485 fitted to them then there are 2 options. Either fit an RS485 Module to the RVG200 and communicate via that or you can buy a converter module to fit between them.
