Hello to all,

I was trying to transfer to a TP170B with a USB to serial cable.

Today I made a serial zero modem cable:

  1 -- NC

  2 ------------ 3

  3 ------------ 2

  4 ------------ 6

  5 ------------ 5

  6 ------------ 4

  7 ------------ 8

  8 ------------ 7

  9 -- NC

The two sides I used a DB9 and then conected this cable betwen HMI and USB to serial cable.

In the settings of the serial port (control panel) on Windows, I disable the "buffer set" and leave the baud rate for 115200.

In HMI settings, I enable the serial port in the transfer settings.

After this, work very well.

Thanks a lot for this forum and all users comments.
