Transductor Calibration

The purpose of the transductor calibration function is to calibrate the transductor by zeroing
the "Amps" reading. You can program this function from the control panel and through the
serial port.

FEATURES/OPTIONS

ASCII

If your MDXII unit has the ASCII host communications option enabled (through an active
panel or a serial port), serial communications will use ASCII characters rather than binary
values. This option provides for systems that require packets to end with CR (ASCII 0Dh) or
LF (ASCII 0Ah) characters. The primary drawback is that the resulting packets will be twice
as long as those using binary values.
The communications protocol stays the same, except that all the binary values are converted to
two hex digits.
Note: ACK and NAK are not translated, and the following characters are ignored: '0' to '9',
'A' to 'F', 'a' to 'f'. This allows any necessary control characters, such as DR or LF to
be added.
The following example shows both the binary and ASCII versions of the transaction of
Command 198, request software version, (see page 7-55).
