The synApps "ip" module has some very simple support. In fact here it is!
corvette:ip/ipApp/Db>more SR630.db
grecord(asyn,"$(P)$(R)$(N)_READ")
{
field(PORT,"$(PORT)")
field(AOUT,"MEAS?$(N)")
field(FLNK,"$(P)$(R)$(N)")
field(SCAN,"$(SCAN)")
}
grecord(scalcout,"$(P)$(R)$(N)")
{
field(INAA,"$(P)$(R)$(N)_READ.AINP NPP NMS")
field(CALC,"$S(AA,'%f')")
field(PREC,"$(PREC)")
field(DESC,"$(DESC)")
}
So it's just an asyn record and an scalcout record to read channel N.

You must be way too young! DB-25 was the standard for RS-232 in the old days of dialup connections with modems. DB9 is the "new-fangled" type of connector, made popular with the PC I think. You can Google RS-232 wiring to see the pin definitions on DB25 and DB9.
The basic signals on DB9 are pin 2 receive data, pin 3 transmit data, pin 5 ground. On DB25 pin 2 is transmit data, pin 3 is receive data, and pin 7 is ground. Of course the definitions of "transmit" and "receive" depends whether you are data terminal equipment (DTE) or data communications equipment (DCE).

Hi,
Does anybody have device support for the SR630 thermocouple monitor?
Also, why does its' RS232 interface come in the DB25 form factor? I had expected it to be a standard DB9 (COM). Any ideas how to hook it up to the good old DB9 port?
