- When used together with COM-DRV(WDM), it can be used in the same way as the COM port (standard COM) on the PC.
Therefore, serial communication can be realized by specifying the COM port number on general-purpose package software that supports RS-232/422/485 communication.
How to set communication parameters differs depending on the general-purpose package software.
For information on how to set communication parameters, please refer to the instruction manual of each package software or contact the developer of the package software.
- The communication parameters should be the same as the communication parameters of the device connected by the RS-232/422/485 cable.
For the communication parameters setting on the device side, refer to the manual of the device or contact the device manufacturer.
- When developing your own application software programs, various serial communication methods are prepared according to the programming development language.
Hints on typical programming languages are summarized in the project creation method topic and the RS-485 half-duplex communication setting topic.
Please refer to it together with the sample program provided by COM-DRV(WDM).
- COM-DRV(WDM) complies with Windows OS and implements COM port.
For this reason, communication parameters can be set for each COM port in Device Manager > Ports (COM and LPT) > CONTEC
Communications property settings.
Depending on the general-purpose package software used, communication parameters may be reconfigured, so the settings on the device manager may not be reflected.
However, if there is no way to set communication parameters on the general-purpose package software, please try it once.
