Product Description
The Delta Controls RS-232/485 Converter converts RS-
232 signals to/from RS-485 signals. It connects to Delta
Controllers through a service tool port using a RJ11 quick
connect cable. The Service Tool Port is built onto many
of Delta’s ORCA controllers, including the BACstat II
(DNS-24/DNT-Txxx) and most of the Application
Controllers.
The Delta Controls RS-232/485 Converter allows Service
Personnel or Building Operators to connect directly to
any BACnet MS/TP network through their PC or
Laptop’s RS-232 Serial Port. Once connected they have
access to the entire network of controllers. The converter
can also be used when flash loading Delta’s BACnet
MSTP controllers to a new version of firmware.
