bx-01 and RS-485 - vic_gates - Feb 20 16:04:00 2002

I need some information from someone at netmedia or anyone else who
has some experience with the networking functions of the bx-01

I am in the process of developing a new product based on the bx-01
which will need to send data out over an rs-485 serial port to a PLC
or some other non-bx system. My question concerns the bx-01
networking functions. Can the network function calls be used to
communicate with non-bx systems or are there some specific formats
that the bx sends or expects to receive when calling network
functions? I know that I can probably just hang a rs-485 transceiver
on the com port and use standard serial I/O calls to communicate, but
it would be nice to be able to use the built in networking functions.
I am only in the planning stages of the design, so I haven't tried
any networking experiments to determine how it would work.

Also, is the network baud rate set with an OpenCom call? I couldn't
find a specific reference in the documentation about setting the I/O
parameters for the network, but I assume that the standard input and
output queues must be setup and the com1 port opened as with any
serial I/O.

Any information information will be greatly appreciated.

Thanks,

Vic

Re: bx-01 and RS-485 - Tony Brenke - Feb 20 21:13:00 2002

I know the bx-01.

it uses a format that you can see.

tap into the com2 port with the network enabled.

run it though the 9 pin conector to conect it to a telnet window.

then you can see what the commands for the network acualy send.
