Pelco Spectra IV and pc firmware uploads

[ronbo 0]

been on this for a while now so thought i best call for help before i go mad.

 

i have the spectra IV SE dome,

i have the IPS cable

a pc with serial

and a null modem cable ( i made my self !!!)

 

the pins the ips cale uses are 2, 3, and 5

 

5 being ground

2,3 data,

now origialy i wired 5-5 2-2 3-3

 

but then found it should be 5-5 2-3 3-2

 

but still dont work ? keep getting connection error on the pelco program

 

any ideas. or does the pc's serial data run on other pin appart from 2 and 3???

 

cheers

upload seems to work but not PTZ control ? the main thing is up load tho

 

why dint i just press the upload button 3 hours ago rather then getting the control to work- prob as the last time i did that it said upload done, but never did anything.

where as not its been uploading for ten min with a download on the screen progressing

 

ideal

You have to make sure all the other comm parameters (baud rate, etc) match the camera, and you need the correct camera ID selected for PTZ control to work.

ya tryed all thet im on pelco D 2400 not polarity-

set pc coms port to that and pelco download software to that too

 

ive updated 3 spectra IV so far so know that part oif it works it just the PTZ contaole but suppose it not a major thing, just strange
