Question about BIT Cable?

I am putting together a transverter control system for my Flex-6700 and I have a question about configuring my USB BIT cable. I see that there are two options int the PTT, delay setting column in the software. One is labeled PTT: and the other is labeled TX: I am trying to understand what these two delays do and how they effect PPT signal timing to a device like a transverter.

Thank you,

Hi Fred, when I wanted to use bit cables I found some basic information in the "USB cables interface guide" but I established the following additional information empirically:

Ptt delay: the amount of time between the PTT being pressed and the bit being activated. RF is produced as soon as the bit is active.

This same time must elapse before the bit is deactivated after the PTT is released. RF is removed as soon as the PTT is released.

Tx delay: the amount of time between the bit becoming active and RF being produced

This same time must elapse before the bit is deactivated after the PTT is released. RF is removed as soon as the PTT is released.

Caveat: This is how I find SSDR version 2.1.33.106 works here. Please check functionality on your system before relying on this summary. 

I hope this helps. 73, Paul
