Serial RS-232 cable question

I am trying to hoop up a radio to my computer. It's a Cat connection.
What i am trying to find out is: Does a Standard RS-232 cable
9 pin on both ends have the same pin outs?

1 to 1 and 2 to 2 and so on.

I have serial cable but does not seem to have
pin outs of 1 to 1 and 2 to 2 and so on.
This might be the reason the program is not seeing the freq on the radio.

Any help would be appreciated.

sounds like you have a null-modem serial cable. Those are not wired
straight-thru.

 

Ok thanks, I'll ask around to see if i can try someone else's Cable
before i go out and buy one.

At the very minimum, you may need to interchange pins 2 and 3 (Rx and
Tx data, repectively) at one of the connectors. Other configurations
are also possible depending on whether you require hard wire
handshaking or not. See this link for more info:

Well the Manual for the Ft-1000MP says to use a standard RS-232 cable.

The cable i have is sealed so can't change anything
I do have some extra serial cables but there 25 pin.

CAT Cable "Pin Outs"

There are only three wires needed between the radio's CAT jack and the
computer's serial port:

For a DB9 connector on the computer end:

Pin 3 to pin 3 = Data from computer to radio

Pin 2 to pin 2 = Data from radio to computer

Pin 5 to pin 5 = Ground
==========
For a DB25 connector on the computer end:

Radio pin 3 to computer pin 2 = Data from computer to radio

Radio pin 2 to computer pin 3 = Data from radio to computer

Radio pin 5 to computer pin 7 = Ground
==========
Check to see if the connection from either pin 3 or from pin 2 of the radio
end of the cable to the appropriate pin on the computer end of the cable is
open.
