Re: "@init handler failed" , "Record initialization failed" and "No reply from device within 1000 ms"

[Dirk Zimoch <dirk.zimoch@psi.ch>]

Hello Hongchunxia

Everything looks fine to me, except that your hardware seems not to be
working. It may be the Moxa (serial to IP converter, right?) or the
serial device.

Have you checked the cable?
Maybe you need a nullmodem cable?

I don't see where you set the baud rate. Use something like
asynSetOption ("MOXA1", 0, "baud", "9600")

Also check number of bits, stop bits, hardware handshake.

Try without EPICS first, do a  'telnet 192.168.127.254 4001'
Does everything work there?

Does the device work when you connect it directly to the serial port of
your PC (or to a USB converter), maybe using minicom?
