SUPER MICRO Computer MIIC-203 Set iPort/AFM’s Own I2C Slave Address, I2C Bus Clock Rate Control

Command: /H[01][CR]	'Hex Only Display [0 = Disabled, 1 = Enabled]
Response: *	'iPort/AFM Ready
Default Setting:	Enabled

Set iPort/AFM’s Own I2C Slave Address

This command sets iPort/AFM's own I2C Slave Address (Hex 2...FE). Subsequent

I2C messages to this address will cause iPort/AFM to become an active Slave device on the bus.

Command: /Ixx[CR]	'Set iPort/AFM’s Own I2C Slave Address
Response 1: *	'iPort/AFM Ready
Response 2: /I89[CR]	'Invalid Command Argument
Default Setting: 6E

I2C Bus Clock Rate Control

Set the I2C Bus master clock rate. (0=23, 1=86, 2=100, 3=400KHz)

Command: /K[0123][CR] 'Set iPort/AFM’s Clock Rate

Response 1: *

Default Setting: /K2[CR]

The iPort/AFM clock rate for standard commands is controlled by the oscillator crystal we use on our microcontroller. This crystal has been selected to give accurate RS-232 baud rates, as the RS-232 baud rate must exactly match the rate used by the host computer. Master I2C clock rates are the fastest possible given the required crystal frequency. Slave I2C clock rates are driven by the external master device, with possible clock-stretching as required to store or retrieve message data.
