RS232 vs RS485

[Roberto]

Hi everybody!
I have a little problem with these serial port.
I have the same application written with LV6 (without VISA driver)
that has a strange behavior. With RS232 work at 600msec with RS485
work at 1200msec. WHY??? Prefix that I have a RS485 card (CP-132 MOXA
PCI) that seems to be setting well (control, termination, transfer
data rate) and the application is modbus.llb of Maarten van Bree.

Regards,
Roberto.

Need to be more specific; What is it that takes 600 ms with RS232 and 1200 ms with RS485?

Yes but thanks I have solved. The problem was the delay of external module.

Bye.
