Hello everyone.  
I´m stuck with a project related with RS485 communication and I hope some of you guys have an idea of viability.  
I have a printer ANSER U2 which use RS485 protocol, additionally I have Serial Support Client module and Serial Support Gateway module installed.  
What I´m trying to do is send a message from pc to printer but is seems like is not responding .  
I validate the port data on the console and it seems like working.  
Some of you have been working with this printers and ignition?

RS485 is not really a protocol. It’s the interface.  
Can’t you print using the ANSER driver?

Hello gilberto.murillo,

Hello everyone  
At the moment the only way to print from pc is using the U2 interface and special cable.  
I have the manual reference from where I got this info.  
I contact Anser U2 from north america but this guys are only sales not technical support.
