Congratulations on choosing the Ameritron ARI-500 Automatic Band Switch for the Ameritron ALS-500M (Ser. No. 13049 and higher) and ALS-600 (Ser. No. 14378 and higher) amplifiers. The ARI-500 is designed to automatically select the correct frequency range on these amplifiers by reading the frequency information or band data from the transceiver. This automatic switch is compatible with most ICOM, Yaesu, and Kenwood transceivers, and the Elecraft K3 transceiver. -
Page 3: Installation
Ensure the amplifier power switch is OFF and the amplifier’s frequency select switch is in the REMOTE position. Plug one of the patch cords into AMP A on the ARI-500. Route the other end to the amplifier and connect it to the REMOTE A amplifier input. -
Page 4: Interfacing Ari-500 To Radio For Keying And Band Data
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. -

LINEAR port on most Yaesu radios. Some Yaesu 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 the proper configuration of the LINEAR port. -

8 (RTS, CTS) on the Kenwood port must be connected together. This ensures that the Kenwood will send the status information to the ARI-500. There is one second delay from when the status of the radio changes until it is sent out over the serial connection. The Remote port on the back of Kenwood radios has the amp-key line needed for the ARI-500, and the ALC input from the amplifier if you wish to use it. - Page 7 Pin 9 ot connected. Note: Pins 7 and 8 on the Kenwood Com Port must be connected together. This ensures the radio will send information to the ARI-500. * The Kenwood TS-480 requires different connections. See the Addendum in the rear of this manual.

Page 8: Operation
The ARI-500 receives band information over the serial interface, while amplifier keying comes from the remote port. The serial communications settings are 9600 bps and the linear amplifier relay must be turned on and must be setup on the radio for the ARI-500 to function properly. -
