Interfacing the ARI-500 to Radio for Keying and Band Data
The ARI-500 RADIO input connection is a RJ-45 jack with specific connections for each radio brand. The diagram below shows the
pin-out of the RADIO input jack. See the specific sections below for more information on interfacing to each particular radio brand.

Interfacing to ICOM Radios
In order to retrieve band data from ICOM radios, the ARI-500 must be connected to the band data voltage output. This can be found
on the ACC jack on the back of the radio. This 13- or 7-pin jack has the band data voltage, amp-key out (goes to ground when the
radio is transmitting), ALC input, and ground. The diagrams below show the connections required between ICOM radios and the ARI-
500. Connection to an ICOM IC-7000 requires an ICOM approved modification. Follow the instructions in your IC-7000 user’s
manual (page 140) to make the modification. Ameritron will not be held liable for any damage caused by this modification to an IC-
7000 transceiver. Also note the ALC connection on the IC-706/7000/718 as this is only available on the ICOM accessory connector.
ALC is available on a separate phono jack on the IC-746/756.
