Control.com - Nerds in Control

I'm currently working on a home automation project using an AMX controller (see http://www.amx.com and search for NI3000). I need to communicate with a Daikin BACnet gateway using RS232 or LAN (preferably RS232) to control the VRV system. Nobody here (in Singapore) seems to know how to do it apart from using the drivers and APIs. I need to write the code out from scratch since I'm programming it into a chip. Need to know comms parameters - baud rate, parity, 7 or 8 data bits, etc.

BACnet.org has lots of info but I can't figure it out.
Anyone out there done it before? Communicate with BACnet on RS232 via terminal or a PLC?

email me please. thanks.

I am looking for the same info. :(

There is a much better way.

Please look up at Google for:
CoolMaster 1000 device.

AVD Australia have a working solution available for Daikin VRV system - an AMX module is available or an AMX processor with the module loaded which can be connected by IP or RS232 to any third party control system. The module is based on communications with the Daikin DBACS IP Gateway - so this must be part of the AC system.

The interface was developed from the ASHRAE STANDARD BACNET Protocol. It can provide the following for each FCU in the system:
Current room temperature
Room Set Temperature point
AC Control CONDITION/OFF
Current AC status (ON/OFF – FAN HIGH/LOW)
Mode – (HEATING or COOLING )
Display AC Error codes
