OK so if TXEN is high during transmission (at the MAX485 DE pin)
That's correct
So if the rest of the wiring is OK (and the A/B lines idle with A high and B low)
you should be closer, though there could also be protocol errors or perhaps
address errors if the drive does not respond
You could check TXEN and RXData (RXData should echo TXData if everything is OK)

After TX(Yellow) then there is no RX(Red) Back.
I have a USB to RS458 dongle to connect to servo driver i use the following settings
Baud 19200, Data bits : 8, Stop bit 1, Parity : Even and Slave : 1. On pktuart driver i can only choose Baud,Address and parity ? the stop bits and data bits is missing ?
The other possibility is on my servo driver modbus response time is 1ms is that too fast ?

If you have TX data and there is no matching RX data back
(and /RE is GNDed), you have a hardware or wiring issue.

After updating firmware :
I get NULL3 is that normal ?

I don't think the firmware update worked TXen is low and only high when TXing

Yes, that should be OK (mesaflash doesn't know about the NTXEN pin)
But unless you get the RX data echo, nothing is going to work
But unless you get the RX data echo, nothing is going to work
That's what a MAX485 expects (active high TXEN)I don't think the firmware update worked TXen is low and only high when TXing

I have other drivers that also don't work with 7i92! I will see if i can build arduino modbus to test TTYtoRS458

Unless you get RX data echoed from TX data if /RE is grounded
and DE is asserted this has nothing to do with the 7I92 and likely
a wiring or hardware issue.

I manage to Echo RX/TX only if TXena is active low
It does not look like the servo drive is replying any data.
