2 One-Wire Battery Peripheral Connector
J2 is a standard shielded RJ-45 receptacle provided for making connections to “1-Wire” devices
such as QS873 VT-Probes (up to 16) and ES771A Remote Mid-string Voltage Monitors (up to six).
Standard cable assemblies have been designed and must be used for applications involving the
QS873 VT-Probes or ES771 Remote Mid-string Voltage monitors. These cables provide simple
plug-n-play from the controller to a QS873A probe, from the controller to an ES771A, and
between QS873A probes and ES771 modules. Consult the section on “1-Wire” peripherals for
further information. Following are the present pin assignments for J2.
