Set the following program parameters in the VX-2200 via the CE-82 software:
In Common Data – Key Assignment, set any one of the keys for the “Ext ACC 2” function.
(This key will be used to switch the VXR-1000 on and off. The “A” icon will be shown in
the radio’s display when the VXR-1000 is switched on.
In Common Data – DSUB-15 – Output Port, set ACC I/O Port 1 for “ACC2 ” function
In Common Data – DSUB-15 – Output Port, set ACC I/O Port 2 for “AF Mute”
In Common Data – Miscellaneous, set External PTT to “Enabled”'
Since you just bought it, you need to use the ( ) color codes for the cable
If it still fails to turn on ACC I/O port which is pin9, the zener diode D1049 has shorted and is not allowing the correct signal to be sent to the VXR-1000. Sorry its underneath the mainboard.
Verify the issue,
In Common Data – DSUB-15 – Output Port, change ACC I/O Port 3 for “ACC2 ” function, but now Pin9 is Pin11
