connection protection. Voltage input range is 12 ～ 48VDC

（terminal block defined as: V1-、V1+、V2-、V2+）.

Important notice:

1. Power ON operation: first of all, insert power cable's terminal

block into device's power port, then insert power supply plug into

power source

2. Power OFF operation: First off all, unpin power plug, then

10/100/1000BaseT(X) Ethernet port

The pinout of RJ45 port display as below, connect by UTP or STP.

The connect distance is no more than 100m. 1000Mbps is used

120Ω of UTP 5e; 100Mbps is used 120Ω of UTP 5; 10Mbps is

used 120Ω of UTP 3, 4, 5.
