Chapter 8 ActiveX LIN Master Object
8.1
The chapter gives a basic description of the ActiveX LIN Master Object. This object is able to perform LIN Master tasks on a PC
and can be used for LIN network control from an HTML page. The following section provides the basic information:
8.2
An ActiveX control is an object that supports the LIN Master functionality. It is delivered as the cabinet (.cab) file “flinbox.cab”. An
ActiveX control is identified by object in an HTML file. If the control has been stored in a “.cab” file, the object must include a
CODEBASE attribute that specifies the URL for this “.cab” file. The following excerpt from a sample HTML file demonstrates how
the object and the CODEBASE attribute are used.
The FLINBOX.LinMaster object has 6 methods and 3 properties:

7.2, Quick Reference
Quick Reference
bool OpenPort([vPortName, vBaudRate]);
— Open RS232 port. It must be called before any other function. Returns true when successful.
void ClosePort();
— Close RS232 port
bool SendMessage(vIdent, vData [, vDataLen]);
— Send LIN message and return true if succeeded.
string RecvMessage(vIdent, vExpectedDataLen [, vData]);
— Requests and receives a LIN message. Function returns the number of bytes received. It returns 0 for checksum
bool Sleep();
— Put the node the Sleep mode. In this mode, the port remains open and the master waits for the wakeup character
– vPortName (string) - RS232 port to open. Optional, default COM1.
– vBaudRate (numeric) - Communication speed. Optional, default 9600.
– vIdent (numeric) - Message ID byte.
– vData (string/array) - Data to send, passed either as a VBScript array or a semicolon-delimited string.
– vDataLen (numeric) - Length of data to be sent. Optional, default 0 which forces calculation of the length from
errors or timeouts.
– vIdent (numeric) - Message ID byte.
– vExpectedDataLen (numeric) - Length of data to be received. When set to 0, up to 255 bytes are received
– vData (output array) - VBScript array of the returned data. Optional, use the LastRecvData property to get the
(0x80, 0xC0 or 0x00). After this is received, the OnWakeup event is triggered. You can handle the OnWakeup event
using the VBScript handler. The Sleep mode is aborted by a call to the Wakeup, SendMessage or RecvMessage
functions. Even in the OnWakeup event, you remain in the Sleep mode until one of these three functions is called.

item at the end).
