compliant PoE injector or switch with +48VDC output on

spare pairs of the network cable conductor 4 and 5, with

corresponding 48 VDC returns on pins 7 and 8 or by sharing

the data pins and their returns. This single network cable

carries both data and power. Maximum cable distance is

328 feet (100m).

RELAY OPTION

When the NTDS digital display is not locked to a NTP

reference, the dry contact relay will actuate.

The NTDS request time from the primary NTP time server.

If no response, then it will send a request to the secondary

NTP time server. If the NTDS is unable to communicate

with either NTP time servers, the NTDS will change its

Current Reference from “NTP” to “Internal Osc

(oscillator)”. This is considered an un-locked condition and

the dry contact relay will actuate.
