Bob,
I have two Z3805A's. One is 1998 HP and one is a 2004 Symmetricom.
The older HP took a VERY LONG TIME to complete site survey.
Both use 24V power.
Both are also RS-232 on lower connector. (even though it says 422 on the
boards)
Use null modem cable (only three wires needed if you make your own cable)
Make sure software (Z38xx) is set to....
9600 baud rate
8 databits
1 stop bit
no parity
Good luck
Jeff
Both
Thank you all for these inputs!
Most importantly, the big question is: Regardless of RS-232 or 422, will
the unit do ANYTHING without communications? Do I need a computer to get
anything beyond the "power" led?
I bought this at the Dayton convention ham flea market, and the guy told
me it was already modified for RS-232. The board inside says RS-422 near
the connector. Without the other LEDs blinking, I'm worried I bought a
dead unit. I had a GPS antenna on it, but it never locked on. Do I need
a computer to enable this thing?
