Supplemental Information

Digimatic Interface

The following describes the standard 10-pin Digimatic connector pinout.

Signal Timing

Figure 1-1 shows a timing chart for the case where the host device triggers a data transfer by asserting

the active-low request signal (/REQ). The gauge then sends data (the DATA signal) that is clocked by the

CK line. In this case, the data ready (RDY) line is not applicable.

Figure 1-2 shows a timing chart for the case where the gauge asserts its active-low data ready signal

(/RDY) to indicate that a new gauge measurement is available. This triggers a data transfer that is

initiated by the host device.
