The ED Keypad uses a 5 pin M12 connector. Pin 1 is the mode pin, pin 2 is Vin, pin 3 is ground, and pins 4 and 5 are CAN High and CAN Low in CAN mode, or USB D+ and USB D- in USB mode.
| Pin | USB mode | CAN mode |
| 1 | Mode | Mode |
| 2 | Vin | Vin |
| 3 | GND | GND |
| 4 | USB_D+ | CAN_H |
| 5 | USB_D- | CAN_L |
The mode pin at power up decides which mode the device runs in: ground for Utility Mode, open for Run Mode.
Mounting:
| Specification | Value |
| Mounting torque, nominal | 4 to 10 in-lbs |
| Mounting torque, maximum | 14 in-lbs |
| M12 connector torque, maximum | 14 in-lbs |
| M12 connector pullout | 15 lbs (66.7 N) |
| Mounting alignment | Less than 1 degree |
| Push, pull and side load, maximum | 45 lbs (200 N) each |
Use the alignment tab and the standard plastic mounting nut. The alignment feature denotes up.
⚠️ In CAN mode a 120 ohm resistor must be added across CAN_H and CAN_L. Without it the keypad may communicate intermittently or not at all.
⚠️ Do not exceed 14 in-lbs mounting torque. Overtightening the mounting nut cracks the housing and voids the seal.
