[TowerTalk] Orion simple question

[Perry - K4PWO]

The answer is, it depends... Some DB/E-9 female to female cables are "NULL"
modem cables that have end to end crossed pins.  Some are not NULL modem
cables... The only way to know is to check to see it pin 2 is connected to
pin 2 and pin 3 is connected to pin 3.  If so, you have a straight through
plain cable.  I would connect the two cables and ring out the pins on the
two free ends.  A straightened paper clip makes a good "probe" for the ends
with female pins.

Subject: [TowerTalk] Orion simple question

Hi Guys,
 
I know this is a bit off topic, but there are some pretty smart guys on  
this list so here goes. I'm hooking up an Orion 2800PX rotor controller to
my  
computer today. The DB-9 ( OK, I already know the correct term is DE9, but 
I've  always heard it as DB-9) serial cable at the computer end has to be 
female and  the db9 at the controller end has to be male. I have a male x
male 
cable and a  female x female cable. If I hook the cables together it would 
be male on one end  and female on the other. What I don't know is if the pin

outs would still be  correct or if they would be reversed. Anyone know?
 
Thanks,
Marty AB5GU
