I purchased 3 PR54-12 boards each with 2 RS485 communications modules on them. 2/3 boards will not connect to the Alpha Station software. Each PR54-12 board’s behaviors are noted below.
Setup:
- USB to RS485 cable connected between my laptop and the RS485 communications module on the PR54-12.
- I2C slave device connected to port 9.
Board #1:
- Successfully changed the E3C device number using the Alpha Station software.
- Works perfectly with our I2C device.
Board #2:
- Successfully changed the E3C device number using the Alpha Station software.
- Never have been able to integrate it with our I2C device. It doesn’t show anything connected to the I2C ports when using the scan feature in the Alpha Station software.
- Will not reconnect to the Alpha Station software. The “Busy” LED stays illuminated continuously.
Board #3:
- Never have been able to connect to it with the Alpha Station software straight out of the package.
Any help or advice is greatly appreciated. Thanks!
