The Mobitec ICU 600 is a control unit used to manage destination signs, route numbers, and next-stop information on public transit vehicles. Programming and updating the unit is primarily handled through the Mobi Info Edit (MIE) software. 1. Software Setup (Mobi Info Edit)
The "Software 35" likely refers to the software configuration or a specific version used with the .
Add Signs: Use the configuration tool within MIE to define the types and dimensions of the signs installed on your vehicle.
Configure Vehicle: Create a virtual vehicle profile that serves as a container for all linked signs.
Create Routes: Input destination text and route numbers into the MIE editing program. 2. Preparing Data for the
Once your routes and signs are configured in the MIE software, you must export them for the hardware.
Simulate: Use the simulation tool in MIE to test how the text will appear on the signs before downloading. Generate Output Mobitec Icu 600 Software 35
: Open the Out File Wizard (Tools > Create Out File or F10) to generate the necessary files for the control unit. Select Unit: Ensure you select from the hardware list during the export process. 3. Downloading to the Control Unit The supports fast updates via external storage.
USB Transfer: Save the generated ".out" files onto a portable USB memory stick. Note that the unit typically supports USB drives up to 2 GB. Upload : Insert the USB stick into the port on the
unit. The update usually takes only a few seconds to complete. 4. Driver Operation
After the software update, the driver can manage the system directly from the unit's interface.
Manual Entry: Use the alphanumerical keyboard or arrow keys to enter route numbers directly.
Automatic Control: If equipped, the system can use GPS or distance measuring to automatically trigger next-stop information during the journey. The Mobitec ICU 600 is a control unit

Let’s walk through a basic example: programming route "35" (coincidentally matching the software version) to display:
Front sign: "35 DOWNTOWN"
Side sign: "35 via MAIN ST"
Using Mobitec Script Editor v3.5:
[ROUTE_35]
FRONT: "35 DOWNTOWN" T=2 S=1
SIDE: "35 via MAIN ST" T=2 S=1
REAR: "35" T=1 S=0
GPS_TRIGGER: LAT=40.7128 LON=-74.0060 R=50
In version 35, the T= (display time in seconds) and S= (scroll mode) parameters are fully honored, whereas older versions sometimes ignored the scroll mode for side signs.
While newer controllers like the ICU 700 and Luminator’s Horizon series exist, the Mobitec ICU 600 Software 35 remains a workhorse for secondary transit markets, school bus operators, and historic tramways. Its simplicity and reliability mean it will likely stay in service for another decade. In version 35, the T= (display time in
However, note that Luminator has placed the ICU 600 into "limited support" status as of 2022. That means no further firmware updates beyond version 35—making this exact software iteration the final, most polished version for this hardware.
The software has three core jobs:
| Function | Description | |-----------|-------------| | Sign Control | Drives Mobitec’s LED/Flip-dot displays (front, side, rear, interior). | | Route Logic | Stores up to 255 routes, each with multiple sign combinations (e.g., “Airport” / “via Downtown”). | | Telematics Bridge | Communicates via IBIS, RS-485, or CAN bus to GPS, fare boxes, and central dispatch. |
Version 35 specifically improved character encoding (better handling of special letters like É, Å, or Chinese characters) and sign transition smoothness (no more flicker when switching between “Not in Service” and “Express”).
Before we decode the "Software 35" designation, it is essential to understand the hardware. The Mobitec ICU 600 is a central control unit designed for electronic destination sign systems in buses, trams, and light rail vehicles. Manufactured by Mobitec (now part of the Luminator Technology Group), this controller acts as the "brain" that manages what passengers see on front, side, and rear LED or flip-dot signs.
