You can configure the serial ports to enable valuable functions.
Enable the port to respond to client devices running K Sequence Protocol.
Make the port available to client devices running Modbus/RTU protocol.
Make the port available for use by the Do-more controller’s Modbus Network Read (MRX) and Modbus Network Write (MWX) instructions
For the RS-232 port, CTS, RXD, TXD RTS, GND are the supported signals. The H2-SERIO-4 also supports 5, 50, 250, and 500 ms RTS transmission delay times.
For the RS-422 port (4 wire) TX+, TX-, RX-, RX+, GND signals are supported. For the RS-485 port (2 wire), RX+, and GND are the supported signals.
The maximum cable length for a 10BaseFL cable segment is 100 meters or 328 feet. You can connect a 10Base10FL cable to switches to lengthen the distance. Each switch can be attached to an additional 100 meters of cable. Two switches connected together extend the total range to 300 meters.
The H2-SERIO-4 Serial Communications Module can support many serial devices. Consider that processing large amounts of serial data decreases the system response time. The H2-SERIO-4 Serial Communications Module contains 2 RS-232 ports with a RJ12 connector and 1 RS-422/485 port (5 position terminal strip). The module is supported by the H2-EBC100 Ethernet Base Controller. You can install a maximum of 8 modules per H2-EBC100.
The power consumption is 80 mA at 5 VDC. The operating environment is 0 to 60°C (32°F to 140°F), 5% to 95% RH (non-condensing). The environmental air requirement is no corrosive gases permitted.
The H2-SERIO-4 Serial Communications Module supports the serial ASCII (full-duplex) and Modbus RTU slave protocols. 1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115200 are the supported baud rates.
The H2-SERIO-4 Serial Communications Module supports the Serial ASCII (full-duplex) and Modbus RTU slave protocols.
