Very good point. I use pins on the db-25 of one of my TRK repeaters for channel steering. With the db-25 off and no steering pins grounded the repeater will fault and not key up.

Another caution
Be sure the DB25 on the back has not had some of the rs232 pins reprogrammed to another function.
If I am programming a repeater that has been programed by someone else I never use anything except the 8 pin on the front until I have checked the pinout on the DB25,
many people dont know to leave certain pins at the default.

I prefer to use the 8 pin modular cable.? That allows me to go to a site and make programming changes from the front panel of the repeater and not have to go in the back and possibly remove a db-25 that connects to something else like a controller.? The less time I spend in the back of the rack, the less time I have to accidentally disconnect something else.

That would work too but the only time that connection is absolutely necessary is when uploading firmware to the repeater (same as the TKRs). Otherwise, the DB25 on the back panel is fine (straight through, non null modem connection)
