Minitor V Programming

[Countrychris80]

I have researched for a few days now both here and on the internet in general, forgive me if I've overlooked a thread somewhere in here.

I have A Minitor III/IV and V Cradles plus a Pager Interface Box, however I have lost my serial cable over the past few years of moving and changing equipment. I have replaced the cable (DB9 to DB25) with a DB9-DB25 Null Modem serial Cable, however I cannot get my pager to read, I constantly get "Communication Error" I believe the serial cable is the issue however I cannot figure out what the
correct type of Serial cable I need would be.

Any Suggestions? I'd much rather spend a few bucks on a new serial cable rather than buying a new PIB
when I have all of the equipment and software in hand, minus that serial cable.

Thanks in advance for any help!

Check this thread,

That might help a bit.

But if you have the correct replacement serial cable, I dont see why it isnt working.

-Programming mode?
-Correct serial port?
-Baud rates?
-May need drivers? not sure with the old stuff but you do for the USB version.

Baud rate is 1200
Correct serial port is set
pager is in programming mode, and firmly seated in the cradle
drivers are correctly installed for the USB Adaptor

When I attempt to read the codeplug, the light blinks once on the
USB to Serial Adapter, the blue bar runs across like it would normally
then stops and give me the communications error.

I've programmed using this cradle, PIB, and USB adapter many times before and with several different pagers, I've ordered a new Serial cable, and will be trying an older PC with on board serial ports to see if this changes anything, and go from there. I'll post an update to this if that helps.

The wiring of a standard DB9 to DB25 (or DB9 to DB9 or DB25-DB25) serial cable is slightly different than a null modem cable with the same plug configuration even though they look ***identical***.

This link take you to a tech info page that has the pin-out wiring for all kinds of RS232 serial cables including DBB9 to DB25 standard and null modem:
