Reference / Harness Number: 104-300-0004

This listing is for one used Clever Devices red LED dot-matrix message display from commercial transit-bus surplus inventory.

Clever Devices specializes in Intelligent Transportation Systems and passenger-information technology for public-transit fleets. Its onboard systems integrate items such as passenger-information displays, automated announcements, destination signage and other vehicle electronics through its IVN architecture.

The unit features a full-length red LED matrix housed in a heavy-duty black extruded-aluminum enclosure designed for commercial transit use.

Electrical / Control Connections

The wiring and terminal area are labeled with:

+12/24V
DATA A
DATA B
GND

The assembly also incorporates:

DIP-switch address/configuration bank
Inline fuse
Multi-conductor wiring harness
Terminal/control board
LED matrix assembly

The 12/24V marking indicates the unit is designed around a low-voltage DC vehicle electrical system, but I would not state exact allowable voltage range or polarity beyond what is physically marked.

Communication

The presence of DATA A / DATA B suggests a differential serial communication network.

However, I would remove “RS-485” from the listing unless Clever Devices documentation or the circuit board specifically identifies the protocol as RS-485.

DATA A/B wiring often indicates that type of network, but it isn\'t enough by itself to guarantee the protocol.

Use this instead:

Communication: Differential Data A / Data B interface

That is completely defensible from the labels.

Clever Devices Transit Application

Clever Devices’ onboard passenger-information platforms are specifically built for transit environments. Its current product lineup includes onboard digital signage, automated voice-annunciation systems synchronized with LED signage, IVN vehicle hardware and other passenger-information systems.

Public transit documentation also describes Clever Devices’ IVN as interfacing with interior signs and headsign systems, reinforcing the transit application of this type of hardware.

Likely use would therefore be:

Transit bus interior passenger-information / message display

I would not call this an exterior destination headsign unless its original mounting location is known. The relatively narrow enclosure looks more consistent with an interior information display, but that is something I would keep conservative.

Part Number Note

This is important for your listing:

104-300-0004 appears to be a harness/reference number.

Since that number is stamped on the Clever Devices wiring harness rather than clearly identified on the display housing as the display assembly MPN, I would list it as:

Reference Number: 104-300-0004

rather than:

Manufacturer Part Number: 104-300-0004

For \'s required MPN field, if there is no other number physically present on the display, I would use:

Does Not Apply

Then put 104-300-0004 prominently in the title and description so it remains searchable.

That is safer than representing a harness number as the complete sign\'s official MPN.

Dimensions

Your draft says both 30–38 inches and then mentions ruler photos closer to 28–30 inches.

I would not publish either number until you take one straight tape measurement from end cap to end cap.

For now:

Overall Length: See photos / measurement to be confirmed

Housing cross-section, if your caliper readings are clear:

Approx. 4.03\" H x 2.46\" D

Condition Details

USED / UNTESTED

This unit was removed from transit-related surplus inventory.

Visually:

LED matrix appears intact
Housing appears structurally complete
Wiring harness is present
Terminal/control area is present
DIP switches are present
No major housing cracks or obvious impact damage observed

Normal scratches, dust, marks and other cosmetic wear should be expected from previous service and warehouse storage.

The unit has NOT been powered or tested.

No representation is made regarding:

LED functionality
Dead pixels
Communication capability
Programming
Vehicle-network compatibility
Internal electronics
Firmware
Sold exactly as pictured.
Installation Notice
This is not a standalone consumer LED sign.
It was designed as part of a vehicle/transit information system and may require:
- Compatible Clever Devices controller/IVN
- Correct wiring
- Correct communication protocol
- Configuration
- Address settings
- Compatible software/data source
to display messages.
That disclaimer is valuable because someone may otherwise buy it expecting to simply connect 12V and type text into it.
Shipping
Wrap the entire aluminum housing in foam or bubble protection, with additional protection at both end caps.
Because the LED lens runs nearly the full length, use a rigid double-wall shipping carton and avoid allowing pressure directly against the display face.
Returns
30-day returns accepted. Buyer pays return shipping.
Unit must be returned in the same condition received and without modification, disassembly or installation damage.
