Relay interface sending Tap to El Capistan V1

My V1 El Capistan does not receive MIDI, but in other posts I’ve seen you can use a relay to send Tap tempo to pedals that don’t take MIDI. I have the morningstar relay interface being used to change amp channels with the Tip of the cable.

Am I correct to believe I can use the ring to send Tap to the Exp jack of the El Capistan and set My tempo that way?

I was thinking I would make a command upon entering a bank to sync Clock 8 taps with the ring of the relay interface

Any input is appreciated, Thanks
