External Switch and cable recommendations for USER PORT

In List mode, the 32 preset frequency selection is accomplished by pulling M4:0 USER PORT pins
LOW. Figure-8 below shows the schematic of the Valon LSW-1. A 7-conductor cable assembly
plugs into the User port and connects to the accessory switch panel. The Phoenix connector
provides screw clamping terminal post so that any external switch contact or TTL signal level can
also be used if desired.
