Item | Description |
|---|---|
Device Name | Allows the user to assign a name for the selected I/O |
device. |
Device Protocol |
Select the type of target device. This also selects the driver used to communicate with the device.
Time Out
The timeout feature periodically checks whether the connection is still valid. If a requested frame is not received in the assigned time, it will be processed as a communication failure. This option is not applied if the protocol is TCP/IP. Values represent multiples of 100ms. For example, a value of 10 represents 1000ms or 1 second.
Retry Count
Assign the number of communication retry attempts after a communication failure.
Serial Port
Select the COM port to be used by the local device (Xpanel). Each COM port may support different communication methods depending on the Xpanel model. You can choose a COM port number up to COM4 or a TTYMCX port up to TTYMCX4. Refer to the table below for more information.
Baudrate
Assign the baudrate. You can select a rate from 300 to 115,200 bps. The rate must be identical to the target device’s configuration.
Parity
Select an option for parity bit usage. Users may select none, even, or odd.
Data Bits
Assign the number of data bits per packet. This option must be equal to the target device’s configuration. Choosing 5 – 7 bits provides faster communication speed but can cause errors if the data contains Korean characters.
If Korean characters are included in the frames, select the 8-bit option.
Flow Control
Allows the user to enable or disable flow control.
Stop Bits
Select the number of bits used to signal the end of the frame. You can select 1 or 2 bits. This option must be identical to the setting on the target device.
Comm Type
Select the communication type used by the target device. You can select RS232, RS422, or RS485.
Station Number
Enter the station number of the target device.
※ Please refer to the corresponding driver manual for further configuration.
The following table lists the communication types supported by each COM port of different Xpanel models.

Timeout (ms) | The maximum time to wait with no response before assuming a communication failure. |
Retry Count | Set the number of retries for sending a frame when communication fails. |
Swap String | Swaps the upper and lower bytes of string word data. |
String Encoding | Specifies the encoding method for reading and writing string values stored on the device. This option can be overridden for individual tags in the Edit Tag menu. |
String Encoding Method | When an invalid character is encountered, the gateway will do one of the following:
|
Serial Port | Select a serial communication port for the Xpanel. COM1: RS422/485 |
Baudrate | 300-230400 bps is supported. The range may vary according to the I/O device. |
Parity | Select the same parity (None, Even, Odd) as the device. |
Data Bits | Select the same data bit setting (7 Bits, 8 Bits) as the device. |
Flow Control | The amount of data being transmitted to itself using the serial communication method can be turn On, Off, or Control. |
Stop Bits | Select the same stop bit setting (1-Bit or 2-Bit) as the device. |
