Product Description
The RS485 UUKL is a dual port, electrically isolated adapter, with two 3-
position, removable screw-terminal connector plugs. Each port has an
RS485 bias switch to set or remove biasing. LEDs verify power and
termination from the EC-BOS-8 UUKL and indicate RS485 trunk
message traffic.
The Dual RS485 UUKL Option Module is to be used with the
EC-BOS-8 UUKL in the Distech Controls' UUKL smoke
control system.
For detailed requirements, specifications, and procedures for
installing and operating UL 864 Listed equipment, you must
refer to the Distech Controls UUKL Smoke Control System
Design Guide (UUKL Design Guide_UG_10_EN).
Failure to meet the requirements or follow the procedures in
the Distech Controls UUKL Smoke Control System Design
Guide can void the UL 864 Listing for smoke control
equipment.
Module Combinations
The EC-BOS-8 UUKL supports a maximum total of two Dual RS485
UUKL modules.

COM Port Assignments
The EC-BOS-8 UUKL has two onboard RS485 ports that always operate
as COM1 and COM2. Installed serial option modules continue COM port
numbering based on proximity to the EC-BOS-8 UUKL, where the option
module closest to the EC-BOS-8 UUKL base operates as the next
available serial COM port(s). For example, if attached directly to the EC-
BOS-8 UUKL, this dual RS-485 option module operates as COM3 (upper
port) and COM4 (lower port).
