Hello team,
I am trying to read value on a device which supports RS485 protocol via TJ45 port.
I am using ewon flexy 205 with FLA3301 extension card
I wired serial cable to the S1 port of the FLA3301.
Then I wired :
- Transmit D- (pin 1) & Receive D- (pin6) of the serial cable to the Transmit D- & Receive D-(White/Blue & Brown) of the RJ45 cable
- Transmit D+ (pin 2) & Receive D+ (pin7) of the serial cable to the transmit D+ & Receive D+ (White/Brown & Green) of the RJ45 cable
I am able to read via RS485 with other brand of gateway so I am sure my device is working.
Unfortunetaly I get my tags in errors
