[foxboro] Integrator 30 Modbus Connection to Multilins

To all:

We have a Foxboro Integrator 30 for Modbus Controllers and I would like to
connect that up to a Modbus compliant device which speaks rs485 Modbus RTU.


The configuration is basically the Int30, an RS232/485 converter and the
Modbus device (Multilin).  The device settings are 2400,8,N,1 (half duplex).

We have tried in vain to make this work.  The ECB block to go on-line.  We
can use a PC and talk to the Modbus device however.  When we try to put the
ECB16 block online it times out.  The RS232/485 converter flashes (ie: the
232 sends out a signal).

We also tried to use an ECB20 block however we got an "Invalid Block"
message when we tried to save it.

Has anyone out there set up a similar configuration.  If so, could you
please forward some details including cabling configuration, dip switch
setting (P0970VB) and the ECB block configuration.  

Thanks in advance.

Yvon..
