CAN bus and terminator
Stationary antenna modules (A) and stationary antenna modules (B) must be connected to the
stationary module using the CAN bus. In the lower part of the device there are two connectors
allowing for connecting these modules. The order in which the antenna modules (A/B) are
connected is irrelevant. ELOKON offers CAN cables of multiple lengths: stationary module to
antenna module (A/B) cable of 4 m and 15 m and antenna module (A/B) to antenna module (A/B)
cable of 4 m and 30 m. The cables may be connected in a row to extend the distance. However, it
should be noted that in order to correct data transmission to be stable, the stationary module and
the most distant antenna module (A/B) must not be further apart than 80 m.
Use the CAN terminator on the last antenna in the row if distance to last antenna is more than
50 m.
