WIRING OPENPATH READERS
Openpath Readers and ACUs communicate via RS-485. The following wire types are
compatible, listed in the order of preference which impacts distance.
● Shielded CAT6A (recommended, additional two pairs can be used for sensors)
● Shielded CAT6
● Shielded RS485 w/22-24AWG (lower gauge, thicker wire is better)
● Shielded CAT5
● Unshielded CAT6
● Unshielded CAT5
● Shielded 22/6
● Unshielded 22/6
Ideally, use one twisted pair for GND and VIN (power) and one twisted pair for +B and
-A (data).
