APPENDIX: NETWORK INTERFACE PIN MAP

The U4S and U4D receivers both have a 25–pin network interface located on the
rear panel. The interface will allow future monitoring and control of all receiver func-
tions, including audio level, RF level, and ''A/B" diversity indication, from a remote
location via an interface device. The table below identifies the signal output by each
pin on the connector. Contact you Shure dealer for addition information.
NOTE: Using any of the pins in the shaded area could result in system mal-
function or damage to your receiver.
