Features:
- Media Adapter Unit assembly for legacy TPN coax infrastructure
- Compact PWA carries separate system-side and media-side connectors
- Infrastructure-group part bridges processor equipment to the control network
The adapter places the processor-facing and coax-network connections on opposite sides of one media interface path rather than operating as an I/O channel card.
Its compact board format omits operator controls, making the part number, connector arrangement, and receiving position the main identification points.
The MAU function belongs to the TPN infrastructure layer, where it transfers communication between node hardware and the network medium.
The Honeywell 51305348-100 TPN Media Adapter Unit Assembly may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Position between node and network
- Network position: The MAU sits between processor-side equipment and the TPN coax path.
- Signal path: Adapter circuitry transfers the communication signal between those two media positions.
- Module class: The assembly is infrastructure hardware rather than a process I/O module.
Separating the two sides of the adapter
- System side: One connector position faces the system-side hardware.
- Media side: The second position continues the path toward the control-network medium.
- Orientation: Connector location must be preserved because the two sides perform different roles.
Compact printed wiring assembly
- Board format: The adapter electronics are carried on a small PWA.
- Operator interface: No operator key or display is present on the assembly.
- Matching points: The board outline and connector placement provide the physical matching points.
Boundaries of the TPN coax application
- Product group: 51305348-100 is grouped as Honeywell Infrastructure hardware.
- Media context: The documented context is the legacy TPN coax network.
- Excluded interfaces: Ethernet or unrelated serial interfaces are not implied by the MAU designation.
