GM300 accesory connector

While messing around with a GM300 I noticed that one of the options could be changed to channel select 1-5. My question to the board is, is this a reference to a mode as in some sort of home revert mode? And if so how does it operate? (switched to ground or some sort of input voltage ect.)
Thank You in advance
Doug

SORRY I GOT MY RADIOS CROSSED UP!!!!
"Select 5" is a form of tone signaling used in Europe. The Sel 5 radios require a different software than a standard GP300 radio.

Doug,
They are used to remotely select a mode (channel).
The lines are used as BCD Channel Selector inputs.
Channel Select 1 is least significant bit and 5 is most significant bit.

Program CS lines for ACT Level = low.

When all are open = operator channel(front panel).

Ex:
CS 1 is low = mode 1
CS 2 is low = mode 2
CS 1 and 2 are low = mode 3
CS 3 is low = mode 4
CS 3 and 1 are low = mode 5

Channel Select is only available on radios with V21.00 or later software.

Hope this helps

TMM,
I did mess around a bit and got it to function. Unfortunately its not quite what I was looking for. I use the radio in conjunction with my repeater for linking purposes and it can get confusing, hence the home revert mode it always gives you a starting point.
Thanks again
Doug

WILL THIS SETUP CHANGE THE TRANSMIT CHANNEL IF THE RADIO IS IN SCAN?

Yes this feature in the RSS will

IT WILL CHANGE IF IT IS IN THE SCAN MODE?
