PURE NETWORKING RS-232/422/485 TO TWISTED-PAIR DEVICE SERVER
2. Overview
2.1 Introduction
The Pure Networking™ RS-232/422/485 to Twisted-Pair Device Server provides an
RS-232/422/485 point-to-point connection over twisted-pair cabling. Each
connected device has an RS-232/422/485 interface. The servers enable industrial
serial devices such as milling machines, measurement instruments, and robots to
connect to LAN-based automation. Other devices typically found on campus
networks—such as card readers, code readers, lab equipment, medical equipment,
and other similar serial devices—can now instantly migrate to a TCP/IP network.
The server has one RJ-45 connector for linking to twisted-pair cable.
The server works in 2-wire half-duplex (RS-485) and 4-wire full duplex (RS-422/
485) asynchronous serial data transmission modes at data rates of up to 115.2 kbps.
And it gives you extended distances up to 0.8 miles (1.2 km) over 24 AWG using
RS-422/485.
A handy terminator feature improves signal quality and distance. Plus, LEDs give
you device status at a glance.
2.2 Components
The server’s front panel is shown in Figure 2-1. LED indicators display the server’s
and the network’s status. Table 2-1 describes the server’s front-panel indicators and
connectors. The numbers in Figure 2-1 correspond to the numbers in Table 2-1.
