Page 13: Figure 1 - Rs485 Transceiver
The NET485 can handle both RS485 and RS422 communications. This is done by connecting the XPort to a pair of RS485 transceivers. The following schematic demonstrates how the circuit is wired for RS422 and RS485. 3.3V 3.3V XPort 485 3.3V Figure 1 - RS485 Transceiver The transmit section of the XPort is labeled TX on pin 4. -
Page 14: Rs422 / Rs485 Network Connections
Overview 1.3 RS422 / RS485 Network connections 1.3.1 RS422 Networks A typical RS422 application uses a four-wire interface (two twisted pairs) and a shield. RS422 networks are often used in a half-duplex mode, where a single master in a system sends a command to a slave device and the slave responds with data. -
Page 15: Rs485 Networks
1.3.2 RS485 Networks RS485 permits a balanced transmission line to be shared in a party line or multi-drop configuration. As many as 32 driver / receiver pairs can share a multi-drop network on a single two wire bus. The length of the network is limited to 4,000 ft. -

Page 59: Pack Control
3.14.12 Pack Control Two firmware-selectable packing algorithms define how and when packets are sent to the network. The standard algorithm is optimized for applications in which the unit is used in a local environment, allowing for very small delays for single characters while keeping the packet count low. The alternate packing algorithm minimizes the packet count on the network and is especially useful in applications in a routed Wide Area Network (WAN). -
Page 60: Send Characters
Device Installer 3.14.14 Send Characters You can enter up to two characters in hexadecimal representation in the parameters "sendchar." If a character received on the serial line matches one of these characters, it is sent immediately, along with any awaiting characters, to the TCP connection. This minimizes the response time for specific protocol characters on the serial line (for example, ETX, EOT, etc.). -
