DSC Keypad
« on: January 20, 2012, 01:56:06 PM »
Hello:

I would like to know if it is possible to use a DSC Keypad Model: 6150 or 6160 to control a PLC, using the COM Port RS-485 on the PLC?

I dont know what protocol the Keypad use...


Thank you...

What brand is the keypad? Does the Keypad has an RS485 port? Is it capable of sending ASCII strings out when a key is pressed? If so then it is possible to connect its RS485 port (provided it has one) to the PLC's RS485 port and the PLC can then read the data sent from the keypad and interpret the data. The PLC uses commands such INPUT$, INCOMM to read data from its serial port and the data can then be interpreted in whatever way you program it to do so.

The Brand is Honeywell 6150. It does not have an RS-485 or RS-232 port. It only has a Data-In/Data-Out connection.

Honestly, I don't know if the keypad can send ASCII strings. Any ideas of how can I find that out?

Thank You.

It appears to be some proprietary communication interface called VISTA and there is no published information that we can find. So I don't think you can interface to this easily.
