Product Precautions
Honeywell DCOM-232/485 is a five-port HSE communication FTA that terminates serial links for a Safety Manager USI-0002 interface.
- Terminates EIA-232 and EIA-485 links
- Provides five HSE communication ports
- Pairs with the USI-0002 module
- Routes safety-system communication channels
DCOM-232/485 operates with USI-0002 module, Shielded serial cable, Safety Manager controller, EIA-232 or EIA-485 field devices.
Its engineered use includes Safety PLC serial gateways, Redundant controller communications, Package-unit serial links, Safety-network maintenance access.
Important Notice: Confirm the complete DCOM-232/485 marking, installed-system configuration, field connections and controlled functional test before commissioning or replacement.

FAQ View All FAQ
-
Does DCOM-232/485 match USI-0002 module in a Safety PLC serial gateways installation?Verify the complete DCOM-232/485 marking, the documented Safety Manager position and the installed USI-0002 module before fitting the assembly.
-
How should DCOM-232/485 be wired when it must terminates eia-232 and eia-485 links?Isolate the circuit, identify every terminal and reproduce the approved polarity, shield and channel assignment for DCOM-232/485; then continuity-test the affected path.
-
Which Safety Manager records should be captured before removing DCOM-232/485?Record the as-found wiring, installed position, active configuration and diagnostic state associated with DCOM-232/485 before disconnection.
-
What controlled test confirms that DCOM-232/485 can provides five hse communication ports?Apply the approved field or simulated stimulus, observe the Safety Manager indication and confirm the intended response without bypassing the normal interlocks.
-
Which Shielded serial cable condition should be checked when DCOM-232/485 reports an abnormal state?Check the Shielded serial cable supply, seating and connection first, then compare channel diagnostics with the recorded DCOM-232/485 baseline.
-
Can DCOM-232/485 be moved directly into Redundant controller communications without validating EIA-232 or EIA-485 field devices?No. Confirm the EIA-232 or EIA-485 field devices, revision, connection scheme and Safety Manager configuration before transferring DCOM-232/485 to that duty.
-
What maintenance evidence is required after DCOM-232/485 is used for Package-unit serial links?Retain the nameplate record, corrective action, final diagnostics and a controlled package-unit serial links functional-test result for DCOM-232/485.
-
How should DCOM-232/485 be returned to service in Safety-network maintenance access?Restore power under control, verify pairs with the usi-0002 module, exercise the intended signal path and release DCOM-232/485 only after the Safety Manager remains in its approved operating state.
