Important Information
This document has been updated to include features and capabilities of Release 4 firmware and
hardware for the BACstat II DNT-T103 and the DNT-T221 products. Although BACstat firmware is
independent from ORCAview, DCU, and Application Controllers, certain BACstat capabilities
require support in the other products. The firmware for the DNT-T103 and the DNT-T221 can be
flash loaded over the network.

FIRMWARE & SOFTWARE OR HIGHER
When BACstats are used with ORCAview, DCU, and Application Controllers loaded with V3.22
firmware/software please be aware of the following issues.
For an MS/TP Network Connection:
• A DSC is required
• Local BACstat display handling and control strategies may be enabled
• Data exchange may be done in GCL+ programming in any DCU or Application Controller
on the MS/TP network
Setup & Configuration
NETWORK COMMUNICATIONS
On an MS/TP network BACstats communicate at a default speed of 76,800 bps. Refer to the
Technical Reference Manual for further detail on configuring the MS/TP network or changing
baud rates. Also refer to the associated BACstat II Installation Guide for network installation
details.
Flash Programming
The BACstat II Release 4 product now offers flash loadable firmware across its network
connection. It is supported by Flashloader V3.33, and operates the same way as other Delta

firmware. Refer to the Flashloader V3.33 User's Guide
