I²C Bus Monitor

MT-4K monitor is an advanced diagnostic instrument helpful in developing and servicing systems equipped with the control bus according to I²C Philips standard. The MT-4K displays the logical status of SDA and SCL lines, records and displays all-important details of the transmission. The instrument is connected to a tested system via 3 wires: SDA, SCL and GND. It does not influence the behavior of the tested system.  View the manual.

Indications of the instrument
The display shows information in two rows. Recorded bytes are displayed in binary form (MSBit first - reflecting the transmission order). In the upper row the address byte is displayed. Lower row displays data bytes that follow the given address. Next to each byte the „+" or „-" mark designates a valid (+) or missing (-) acknowledge. The presence of the acknowledge signal is the most important indication for service purposes.

• complete information about communication on the bus - all bits recorded and displayed,
• recording can be narrowed to transmissions headed by specified address (each address bit can be defined as "0", "1" or "don't care"),
• recording can be narrowed to capturing nothing but addresses,
• acknowledge bits displayed for each byte (simplifies fault finding in systems not equipped with "error messaging" feature),
• 4 kilobytes storage capacity,
• library of ic addresses,
• useful in both: service and development work.
