TX req and Interlock
we would need to make an interlock between 4 flex 6600s. We purchased an EA4TX device that manages 5 radios with different priority levels and two inband radios. By making the connections indicated in the manual we connected ACC TX and ACC TX Req to the respective ports of the interlock equipment. The problem is that, in MS operation where only one signal per radio is allowed in tx, the second radio still goes in tx and is not interlocked despite the interlock equipment supplying a voltage of +5 vdc to the TX Req pin . Practically, if the radio goes into TX, the TX Req does not inhibit it. ACC TX has been set for the band in use and regularly goes to gnd and TX Req set active high regularly goes to + 5 VDC. Is it normal? If so, how can the four radios be interlocked to comply with the contest rules?
thank you for your attention, Antonello IT9EQO

Hi Antonello,
Have you figured this out?

For 2 radios, RCA out from one Radio ACC TX, TX1, 2 or 3 into RCA TX REQ on the back of Radio 2. Set the Interlock to Active Low. When Radio 1 is in TX, Radio 2 will not send RF.
Do the same for Radio 2 to Radio 1. It just takes 2 RCA cables.
I don't know the box you are using, but I would do some voltage measurements and test the RCA TX REQ is working as it should. Make sure you also set RCA TX REQ to Active High for the 5V. Also, check TX Band settings and ensure you have RCA TX Req selected and the correct
Simplify your testing first and then add more radios.
