Communication to the TSSOP board can be accomplished either through the RJ-11 jack by connecting the provided standard six conductor RJ-11 cord. A battery should be connected between the VDD (positive terminal) and VSS (negative terminal) and provide enough voltage to power the DS2502. In order to program the device, a 12 Volt programming voltage should be connected between VPP and VSS.
