RS422/485 to Ethernet packets. You can now read RS422/485 data over Ethernet from anywhere in the world. Using RS485 two-wire mode, you can also connect the NET485’s serial interface to multiple devices in a multi-drop network. 1.2 Overview of RS422 / RS485 RS232 is an EIA standard transmission system and has been around since 1962. -
Page 10: The Rs485 Enable Signal
One of those options is the transmit enable, which is labeled “RS485 TX Enable”. The Quick Start Guide explains how to configure the NET485 for proper RS485 operation. WARNING: The NET485 comes from the factory already configured for RS485 operation. If you reset it to factory defaults, you will have to reconfigure the unit for RS422/485. - Page 11 Overview This version of the configurable pins window shows CP1-3. Web Manager 2.0.0.2. The NET485 uses Configurable Pin 1 (CP1) for the transmit enable. You must enable RS485_TXEN during the configuration process. (See the Quick Start Guide for details) The NET485 uses in the Active High condition.

NOTE: You cannot configure the NET485 through the serial port. The boot program has no control over the Configurable Pins, so the NET485 will never be able to send data during the boot period (initial 5 seconds). Note: Some unexplained errors might be caused by duplicate IP addresses on the network. Make sure that your unit's IP address is unique. - Page 58 Setup Mode via the serial port is NOT mode on the device server via NOT supported on the NET485 supported on the NET485.
