| Prox/Velom I/O and Multimode Prox/Velom I/O | 10 kΩ for Prox/Accel 3.5 MΩ for Velomitor |
| Outputs | |
| Front Panel LEDs | |
| OK LED | Indicates when the 3500/44M Aeroderivitive GT Vibration Monitor is operating properly |
| TX/RX LED | Indicates when the 3500/44M Aeroderivitive GT Vibration Monitor is communicating with other modules in the 3500 Rack |
| Bypass LED | Indicates when the 3500/44M Aeroderivitive GT Vibration Monitor is in Bypass Mode. |
| Buffered Transducer Outputs |
The front of each monitor has one coaxial connector for each channel. Each connector is short-circuit protected. |
