H2-SERIO(-4) Overview
With the H2-SERIO, three additional RS-232 ports can be added to your Do-more system. On
the other hand, the H2-SERIO-4 can give you two additional RS-232 ports and one RS-485 or
RS-422 port. As many as eight of these modules may be added to the local base, adding up to
24 serial ports (there is no means of using these modules in Ethernet remote bases).
The serial ports of the H2-SERIO(-4) support the following functions which can be selected
in the Module Configuration of the Do-more software (as seen below):
• Do-more Programming - Select this option to setup the port to work with the Do-more Designer
programming software.
• K Sequence - Select this option to have the port respond to client devices running K Sequence
protocol.
• Modbus RTU Server - Select this option to have the port respond to client devices running
Modbus/RTU protocol.
• Modbus RTU Client - Select this option to make the port available for use by the Do-more
controller’s Modbus Network Read (MRX) and Modbus Network Write (MWX) instructions.
• General Purpose - Select this option to make the port available for use by the Do-more controller’s
Input String from Device (STREAMIN) and Output String to Device (STREAMOUT)
instructions.
Baud rates, parity and communication bit settings are accessible by selecting the Device
Settings... button located below the General Purpose selection or through the Device
Configuration section of the System Configuration window. Baud rates up to 115,200 are
supported.
