P275 connected to DIGI TRansport WR44 serial server
« on: September 12, 2017, 06:13:42 pm »
Hello

When directly connected to a PC through USB to serial cable, I can access to P275 with commands using Realterm.

But when I connect it to serial port of the Digi Router (configured 19200,8,None,1,None,No,No) I can't obtain any printings on terminal application.
I attached serial configuration on Digi WR44 router and port server.

Serial port of Digi router and port server is listening on TCP port.
P275 is connected to Digi through serial cable provided by Pira and male-male direct cable to adapt DB9 gender plugs.

Any hints please?

Best regards

Alain

Using a direct serial cable with same gender on each end is suspicious.

It should be crossed I think.

2-3, 3-2, 5-5

The P275 is DCE and the Digi seems to be DCE as well.

In fact I use the cross cable you provide + a direct one just to change the genders.

The cable supplied is DTE-DCE, it is a direct cable!
