Replicating a PCM signal with SX/B

noel

I have a PCM signal·that I·would like·to be able to record and·playback on the SX/B...diagram attached. I would appreciate any suggestions?·thx

We're going to need alot more details about the signal.

I agree with Bean.
But observing the picture,
There appears to be a 5 division (100 msec) rest period, then a·burst of 50% dutycycle
signal (5V toptop, period = 0.2 division = 4 msec).
If this is a live signal, why not capture it with the sx?
If the picture is from some documentation, does the doc not explain the signal?
What is it used for?

Sorry I'm new to this...here are some more details that I hope are what you're looking for.
Signal is from an automotive scan tool...it is a 5V signal that appears proprietary and not one of the standard vehicle networking protocols.

Signal starts high, goes low for 105ms
toggles hi 2ms, then lo 2ms repeating for 5 cycles
the following sequence (1=hi, 0=lo)·repeats 6x, width of each·pulse is .6ms
110100110100
final sequence repeats 1x
1001
signal ends high

Per Peter's suggestion I would love·to capture·it on the SX for playback if possible, as an alternative to·defining the signal in code? I may need to do other signals as well and SX code to·capture/replay·may be·easier to reuse. I was looking for code examples in this forum to start with and modify if you (Bean or Peter)·happen to·recall previous samples·that might help.

Thx
