Mark -

Never mind; I found the answer in the DOCS (of ALL places!  Jeesh!).

I'll just wire up a couple of opto-isolators to act as "relay closures" to the AppDig
box and be done with it.

Sorry for the question when the answer was already so readily available!

Bill

  Mark,

  I'm using an Ocelot with SECU16 module.  AppDig tells me that I must use "A/D" mode
of an input port when testing (monitoring) a standard TTL signal (+5 or 0, which represents
OFF and ON in this particular case - homebrew digital BOB with SmartLink sensing probes
for TV, Stereo, VCR, DBS and DVD).

  QUESTION:  How often does ECS "sample" an Analog-Input-K type item?  Once per pass?
 Once per minute?  Something in between?  Is the time between samples a settable parameter
somewhere?

  I'm using ECS 4.3.004 (yea, I know, I should "upgrade" but I'm just now getting things
hooked up and wanted to work with what I knew worked (or t-thought- would work!!!) 
 <GRIN!>

  Thanks,
  Bill Walters
