I don't know those specific devices so I did some googling around..

I found this page that could be useful

There are those:

D series COMMUNICATION IMDRE03_E3.pdf (1.16MB)
http://www.rkcinst.com/english/pdf_manual/imdre03_e3.pdf

This document says communications is RS-485 or RS-422.
There is description how communications with controller works.
The document comes even with Basic source code for commications.


CB series COMMUNICATION IMCB03_E5.pdf (904KB)
http://www.rkcinst.com/english/pdf_manual/imcb03_e5.pdf

This says communications is through RS-485 at 2400, 4800, 9600 or 19200 bps. Document lists the commands to send to controller.



For interfacing RS-485 or RS-422 to a PC, you need to have a suitable adapter that converts the computer signals to those formats.
The documents showed RS-232 to RS-422 converter in use and the manufacturer web page lists that the same manufacturer makes COM-K (USB communication converter).

I quess that quite many commercially available RS-232 to RS-485/422 converters would work in this application. You need a converter than then write suitable software for the PC to make the communications to work (I don't know any ready made software suitable for this).

Very good question..

Heater control section - I am using a RCK CB100 temperature controller reciving feedback signal from the PT 100 temperature probe to close and open 3 pole Lovato relays x4.

Humidifier section - I am using a REX D100 Humidity controller (Panel mounted) reciving feedback signal from the Humidity probe to close and open FINDER 250V at 10A single pole relays x4.

I dont know if this answers the question. :(

How those Heater banks and humidifier banks are controlled now ?

What kind of control interface do they have now ?

:oops:
Please help!!! :?:
I need to know how can I interface Heater banks and humidifier banks to the PC. This must allow me to insert setpoints, edit setpoints on the PC.

Thank
