PPC-21W.
·LAN A / LAN B· 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.
·COM3 / COM4· RS-422/485 serial line.
2 COM ports for RS-422/485 serial lines, 50 ~ 115.2 kbps.
The PPC-21W automatically detects the RS-422 or RS-485 signal. In RS-485 mode, the
PPC-21W automatically detects the direction of the incoming data and, therefore, it can
change the direction of transmission accordingly; no link signal is required (for example,
RTS). This allows an RS-485 network to be created with only two cables. Additionally,
prewritten software for half-duplex RS-232 environments can be maintained without the
need to be edited.
