ATTENTION
Before connecting the PT-G503-PHR-PTP to the DC power inputs,
make sure the DC power source voltage is stable.
Wiring the Digital Inputs
The PT-G503-PHR-PTP has one digital input, DI 1. The DI consists of two
contacts from the 5-pin terminal block connector on the
PT-G503-PHR-PTP’s bottom panel. The remaining contacts are used for
the PT-G503-PHR-PTP’s Relay 1. The top view of the terminal block
connector is shown below.
Take the following steps to wire the digital input:
STEP 1:
Insert the negative (ground)/positive DI wires into the
┴
/I1
terminals.
STEP 2:
To keep the DI wires from pulling loose, use a small flat-blade
screwdriver to tighten the wire-clamp screws on the front of the terminal
block connector.
STEP 3:
Insert the plastic terminal block connector prongs into the
terminal block receptor, which is located on the PT-G503-PHR-PTP’s
bottom panel.
Auto MDI/MDI-X Connection
The Auto MDI/MDI-X function allows users to connect the
PT-G503-PHR-PTP’s 10/100/1000BaseT(X) ports to any kind of Ethernet
device, without needing to pay attention to the type of Ethernet cable
being used for the connection. You may use either a straight-through
cable or cross-over cable to connect the PT-G503-PHR-PTP to Ethernet
devices.
