Motorola xpr 8300

Our club has two Motorola XPR 8300 repeaters that I want to link with allstar. The repeater is never going to be used for DMR. Just analog only on both ends. Has anyone done this? I am not having any luck. Does the repeater need to be set for internal or external controller? What else needs to be set on the repeater? Does the Allstar node need to be configured to Receive on one usb and transmit on another? I am still learning some of this stuff but I just know enough to screw something up. When I disconnect the current arcom, the repeater goes dead. Set of course for external control.
