[Elecraft] New Topic - KX3 Rig Control via Computer Interface

[Julia Tuttle]

Do you mean KPA100 or KXPA100? I assume KXPA100. (I believe the KPA100 is
an internal module of the K2.)

The KXPA100 has a jack labeled "RS232 (PC)" that should work like ACC1 on
the KX3.

The KX3 to KXPA100 adapter cable has a jack that provides access to the
GPIO line on ACC2 on the KX3, but it's not an identical connector.

Page 17 in the KXPA100 manual has a wiring diagram.

If you share more about what you're using ACC2 for, we might be able to
help with software or wiring tweaks to do the same with the KXPA100 in the
picture.

73,

Julie
