Data Packetizing

Start Frame Byte(s): This value specifies a special character or characters that signals the start of a data-string. Range from 0x00 to 0x1F and options of “None” and “Other”. If “none” is selected, there would be no Start Frame Byte. If “Other” is selected, the user can configure a Start Frame Byte of up to six bytes.

Default value: none

End Frame Byte: This value specifies the character that signals the end of a data-string, and the data would be sent to the destination unit right after the radio receives the designated character. Range 0x00 to 0x1F.

Default value: 0x0D = Carriage Return

If the user specifies ‘None’ (or leaves the field blank), this will signify that there is no End Frame Byte and data will be sent immediately once the WiSER2400 receives the next Start Frame Byte.

Max Bytes/Pkt: This value specifies the maximum number of bytes the WiSER2400 will hold before they are sent off.

Range: 1 to 200 bytes.

Default value: 200 bytes

Serial Mode

Data Only Mode: When this mode is activated, the WiSER2400 serial port would accept only communication data traffic and ignore the configuration command. This mode will stop the communication between the administrative software and the WiSER2400. To re- gain the access to the WiSER2400 for administration, refer to the Troubleshooting Section for recovery instructions.

Default value: Data Only Mode

Data and Command Mode:

In this mode, the WiSER2400 serial port accepts both communication data traffic and the administration commands.
