For Enter-Exit applications, the RS-485 electrical interface must be connected between the two EX-10 Exciters and the
RXR-10 Receiver (see Figure 11 for a wiring diagram). The total length of the RS485 wiring must be less than 500 feet.
NOTE: The RS485 interface is only required for two-lane operation. Do NOT connect the RS-485 wiring when in single-
lane operation.

The instructions provided in Section 4.0 apply for Enter-Exit operation; however, they need to be performed for each
vehicle travel lane independently. You may consider reducing each Receiver’s sensitivity to minimize interference
between the vehicle travel lanes.
