Ethernet (Fast Ethernet / Gigabit Ethernet).
The PPC-21W has 4 RJ45 LAN ports, two at the lower end (LAN A / LAN B) and two at the
upper end (LAN C / LAN D). All ports comply with the IEEE 802.3u 10 / 100Base-T CSMA/CD
standard and are compliant with the IEEE 802.3ab 1000Base-T specification.
The PPC-21W can be configured as an additional node on a local network or it may be
connected point-to-point to the CNC.
Connector.
All ports have two LEDs to indicate whether the PPC-21W is connected to the network (green
LED) and if data are being transmitted (yellow LED).

Cable characteristics.
Use a specific Ethernet cable with the following characteristics.
Characteristic.
Type.
Impedance.
Maximum length.
Transmission speed.
The PPC-21W permits a connection at 10 MHz, 100 MHz or 1000 MHz; by default at 10 Mhz.
Use a cable having the recommended characteristics to ensure a transmission at 100 MHz
or 1000 MHz. Even so, since the transmission speed depends on the configuration of the
network (number of nodes, their configuration, etc.) a 100 MHz or 1000 MHz transmission
might not be stable. In these cases, we recommend to lower the transmission speed.

LED.
Meaning.
A (green)
Connection LED. The LED turns on when the PPC-
21W is connected to the data network.
B (yellow)
Activity LED. The LED blinks when data is being
received/transferred.
Description.
Standard shielded ethernet 10Base-T cable (10/100 MHz
connection) or 1000Base-T (1000 MHz connection).
Use a crossed cable to connect for the point to point connection to
the CNC.
10/100 MHz connection Cat.5 (100 - 120 ) or greater.
1000 MHz connection Cat.5e (100 - 120 ) or greater.
100 meters (328 ft).
