5. Confirming Wiring and Cable Lengths

5.1 When Using IRDs

Names of IRD parts

BNC connectors

· BNC cables are not included accessories.

Wiring for IRAs and IRCU/IRCUDAN

You can install up to four IRAs from each TX/RX terminal on the IRCU/IRCUDAN. A maximum of 16
IRAs can be installed by using IRDs.

Checkpoints

①

Do not exceed 100 meters for the total length of cable connections.

When installing multiple IRAs, use the same total cable lengths from the IRAs to the IRCU/
IRCUDAN. (We recommend a difference of less than 3 m.)
