Hi guys,
I'm new to DSE 7320 and maybe this question is not relevant to the topics. But I hope any of you could help me out of this case.
So yesterday, I try to connect DSE 7320 to my laptop using modbus RTU. I was using an RS232-usb converter (trendnet TU-S9) and a null-modem/cross-over cable (as specified in "DSE7320-MKII-Operators-Manual" page 26 of 168) and modscan64 . Unfortunately, I failed to connect.
Could you help advice? Actually, I have one assumption of problem cause. It is stated that "DSE DOES NOT recommend use of USB to RS232 convertor...", in the same page as mentioned above. BUt, is it really the problem? Since for me there is no enough explanation of why they not recommending this.
What I've checked and make sure:
1. it is modbus RTU
2. same baud rate and same byte format (8 bit,No parity, 1 stop bit)
3. working USB-rs232 convertor (tested for other use)
4. properly connected cross-over cable (since we made it)
5. working modscan64 (tested for other use)
Will really appreciate any suggestion. Thanks.
