ARI-500 Automatic Band Switch for ALS-500

Interfacing to Yaesu Radios

Yaesu radios output band information using a 4-line BCD format. The band data
lines can be found on the Linear port on most Yaesu radios. Some radios share
the CAT port with the Linear port. The radio must be configured so that the port
is in Linear mode or the band data information will not be sent to the ARI-500.
Check your radio's manual to determine proper configuration of the Linear port.
The diagram below shows the connection to the ARI-500. Double check with
your radio's manual to ensure the correct connections for the Band Data.
