About This Item
Overview
Details
With three power options, Model ULI-224TB (BB-485BAT3-B) is ideal for field service applications. Use battery power with a low-power RS-232 port (laptop), when handshake lines are unavailable, or when a PSU is not possible. The unit draws available power from the RS-232 port getting additional current from the batteries. If you have a full-power port and handshake lines, turn Off the battery switch to use port-powering, saving the batteries for emergencies. (Battery On/Off switch conserves battery life; it does not turn on/off all power.)Documentation
