Attached below is a document showing how to wire multiple PIH 931D keyboards to one DVR / NVR.
The document is based on the PDR-2160 but the process is applicable to almost all LILIN DVR and NVR's including the NVR 116.
Wiring multiple PIH-931D keyboards together requires an additional piece of hardware only available on direct request from LILIN. Please advise if you intend to use multiple devices together when ordering.
