ST4 port pinout

Hi,
I need the following information about ASI ST4-port pinout. According to the manual the pinout is like the one in the picture attached. But in this picture the RA- command seems to correspond to pin 1 that cannot be, as pin1 is not wired (NULL pin). So I'm not sure I understood this scheme.
Can you confirm I got the correspondence pin <-> command correct?

PIN 1= NULL
PIN2 (black) = COM
PIN 3 (red) = RA+
PIN 4 (green) = DEC +
PIN 5 (yellow) = DEC -
PIN 6 (blue) = RA-

Thank you

Hi,
First, all the ST4 port of our camera is designed in the same way.
Second, for the holes on the camera side, the line sequence is correct. for the port on the cable side, it is also corrent.
For the shotcut, it is right, just one thing you should take care. It's the front of the port. When you connect it to the camera, you need to turn it around. In other words, if you see it from the back of the port, it will be right.
Thanks
Chad
