There are several timed update formats of the ASCII dump available:
•
0 none
Timed Outputs disabled
•
1 Human
Output tailored to reading by human
•
2 Machine, no checksum
Output tailored to use by a host computer
•
3 Machine w/ Checksum
Output includes a trailing Checksum to insure data integrity
•
4 Tab Delimited
Output for MS EXCEL file format
The default format is
Human readable
. Configuration of the Service Port timed format is available
through the advanced level 1 interface. The format of the Human readable data is:
Mode Reading Units ALM1 ALM2 FLT
.
(see notes 1,2,3)
The format of the
Machine, no checksum
data is:
Concentration Reading/range Device type Code Fault Code Alarm 1 active Alarm 2 active
Display range code
(see notes 1,2,3)
The format of the
Machine, w/ checksum
data is:
Concentration ReadingRange DeviceType FaultCode Alarm1Active Alarm2Active
DisplayRangeCode CRC Checksum
(see notes 1,2,3)
The format of the
Tab Delimited
data is:
Seconds since unit powered on
tab

Alarm2Active
tab
Fault
(see notes 1,2,3)
Notes:
1.
The Fault Code, FLT is output only if active, otherwise, it is deleted from the string.
2.
The Fault.L code is represented by the Error messages listed in the FAULT section of
this manual. The Fault code is bitwise (one bit in the code represents 1 fault). It is a 32 bit
number, with fault number 1 (Oven or sensor is warming up) being the most significant bit,
which would be 80000000 in hexadecimal. A typical fault code during warn up for a model
7100P Portable analyzer would be C0040000 in hex, which would represent fault codes 1, 2
and 14.
3.
Alarm Active is represented by “1”, alarm not active is represented by “0”.
II.
The
Advanced Level 1 Access
is available to the user via a PC or directly at the Model 7100P
Portable analyzer control panel. Access to level 1 can be accomplishe
d on a PC by typing “setup”
when viewing the standard ASCII dump. A series of menus will display on the PC screen allowing
access to changing the setup configuration. Some features of this level access may also be initiated
directly at the Model 7100P Portable analyzer by pressing in the mode button for 5 seconds.
NOTE: Do not attempt advanced level 1 or 2 access without reading
“Service Port : Changing the factory settings” section of the appendix.
III.
The
Advanced Level 2 Access
is available to the user via a PC by use of a password. This level
access allows manipulation of code settings and should only be attempted with direct consultation with
our applications engineering staff.
