- Display Size: 10-inch diagonal, independent mount
- Power Consumption: 4.6 watts max
- Operating Temperature: -20°C to 65°C (-22°F to 149°F)
- Storage Temperature: -40°C to 85°C (-40°F to 185°F)
- Humidity: 95%, non-condensing
- Weight: 1.07 kg (module only)
- Dimensions (Module): 241.3 mm x 24.4 mm x 241.8 mm (9.5 in x 0.96 in x 9.52 in)
- Inputs: High-speed network, RS232 port (touch controller data)
- Outputs: OK LED, TX/RX LED, VGA port (analog RGB and sync signals), Front Port (24 Vdc power out, VGA signal out, touch commands in)
One distinctive spec is the low power consumption of 4.6 watts max. This means the module generates minimal heat, reducing stress on surrounding components. Additionally, the wide operating temperature range ensures reliable performance even in harsh conditions.
Installation and Setup
Installing the 3500/94M-04-00-00 is straightforward. The module occupies one full-height front slot in the rack. The I/O module takes one full-height rear slot. For the KVM extender, mount it on the shelf top. Ensure proper ventilation around the module to maintain optimal operating temperatures.
Connect the high-speed network cable to monitor status and data. Use the RS232 port for touch controller data. The front port provides 24 Vdc power out, VGA signal out, and touch commands in, simplifying cable management. Always follow the manufacturer's manual for detailed wiring instructions.

Maintenance and Reliability
Regular inspection of the 3500/94M-04-00-00 ensures long-term reliability. Check the OK LED to confirm proper operation. The TX/RX LED indicates communication between system modules. Periodically verify that all connections are secure and that the display is free from dust and debris.
The module's robust design, with a wide temperature range and high humidity tolerance, minimizes downtime. Its low power consumption also contributes to a longer service life. For any maintenance tasks, always refer to the official Bently Nevada documentation.
Compatibility and Integration
The 3500/94M-04-00-00 requires the 3500/22 Transient Data Interface (TDI) module. It also needs specific firmware and software versions to function correctly. Ensure your system runs at least the following:
- 3500/94M Firmware 4.06, Rev. C
- 3500/22 Firmware (TDI) Rev 1.71
- 3500/01 Software (Rack Config) Rev 5.6
- 3500/02 Software (Op Display) Rev 2.21
- 3500/03 Software (Data Acquisition) Rev 1.22
This module is designed for seamless integration into existing 3500 monitoring systems. Verify compatibility with your current setup before ordering.
Troubleshooting Common Issues
If the display is not showing data, first check the OK LED. If it is off, the module may not be receiving power or may have a fault. Verify the network connection and ensure the TDI module is functioning. If the TX/RX LED is not blinking, communication between modules may be interrupted.
For persistent issues, consult the troubleshooting section of the Bently Nevada manual. Always follow safety protocols when handling electronic equipment.
