SUPER MICRO Computer MIIC-203 manual I2C General Call Control, Hex Only Display Control

Page 35

The RTS/CTS protocol uses two additional wires in the cable connecting communicating devices. The RTS wire is an output signal. It indicates that the device generating the signal has buffer space available, and can receive. The CTS wire is an input signal. It indicates that the other device has buffer space available, and can receive.

In general, XON/XOFF requires a minimal three-wire connection, Ground, Transmit Data, and Receive Data. This protocol does insert control characters into the stream of data, and may not be appropriate for all Host systems. If supported, these control characters are normally automatically stripped out of the data stream by Host communication driver software, and are not visible at the application program level.

The RTS/CTS protocol requires a serial port, cabling, and Host communication driver software that supports the additional control signals.

Command: /F[01][CR]	Flow Control [0 = XON/XOFF, 1 = RTS/CTS]
Response: *	'iPort/AFM Ready
Default Setting:	XON/XOFF

I2C General Call Control

This command enables or disables iPort/AFM response to I2C Bus General Call (Address 00) messages.

Command: /G[01][CR]	' I2C General Call [0 = Disabled, 1 = Enabled]
Response: *	'iPort/AFM Ready
Default Setting:	Enabled

Hex Only Display Control

This command controls Hex Only (~00...~FF) output of Master or Slave received data.

When enabled, all received I2C message data bytes are displayed in Hex (~00…~FF) form.

When disabled, received I2C message data bytes representing ASCII printable characters are displayed as their ASCII printable character. Non-ASCII printable data bytes are always displayed in Hex (~00…~FF) form.
