Title: Serial port data for Digital Panel Meter
Post by: Taka_Y on October 28, 2020, 10:42:05 PM

Hello Sir,
I want to display the value of the vacuum gauge on the Digital Panel Meter via serial communication.
It's easy if the vacuum gauge is Modbus-RTU, but that's not the case.
Read command:"#01RD<CR>"
Interval time:500ms
Please help me!
Best regards,
Taka

What does the manufacturer suggest to use for communication with that device?

Thank you for your reply.
It has only 485,232 serial communication.

It looks like you will have to create a code to send strings as they are defined in the manual of that device.

Just Google it and there will be bunch of examples in VB Net or C# on how to do serial communication.

The data sheet is also mentioning ASCII protocol, so you can try using ModbusASCIICom driver.
