Confidential / Draft - Do not copy

The 

 command enables the module to be connected to external I²C devices. The I²C datastream is

mapped through an internal I²C driver to and from an ASCII hex protocol which can be exchanged with an exter-

nal application via V24.

The 

 write command configures and activates the I²C interface and changes from command mode into

data mode. All values must be given in hexadecimal format (0 - 9, A - F) without "0x". For details on data mode

please refer to Section 

Parameter returned by the 

? read command. 

Indicates whether or not the I²C channel is used. When the channel is open and the ME is in data mode, the

read command can only be used if one of the remaining interfaces is available. For example, when the channel

was opened on ASC0, you can use ASC1, MUX channels or USB to check the status.
