4.1.2.4.2 Human Readable data format – SSERFMT=1
The factory default format is Human Readable and can be changed via the analyzer control panel, or
through the RS-232 interface in Standard Level Access. Human Readable data is presented in dynamic
columns (columns appear only when data is present). It is intended for most users, to aid in setup and
maintenance of the unit. Column headings from left to right: Mode | O2 Concentration | Alarm-1 status |
Alarm-1 status | list of Fault codes active.
4.1.2.4.3 Machine data format with NO Checksum
Machine format with NO checksum can be selected via the analyzer control panel, or through the RS-232
interface in Standard Access level. Machine format with NO checksum data is streamed in packets
defined by start/stop transmit bits. The order of data in each packet is as follows: Start Transmit | O2
Concentration | Fault codes active | List of Fault Codes | Alarm-1 status | Alarm-1 status | End Transmit.
For detailed information on data formats, please contact the Neutronics Service Department.
4.1.2.4.4 Machine data format WITH Checksum
Machine format with checksum can be selected via the analyzer control panel, or through the RS-232
interface in Standard Access level. Machine format with checksum data is streamed in packets defined
by start/stop transmit bits. The order of data in each packet is as follows: Start Transmit | O2
Concentration | Fault codes active | List of Fault Codes | Alarm-1 status | Alarm-2 status | Checksum |
End Transmit. For detailed information on data formats, please contact the Neutronics Service

4.1.2.4.5 Tab delimited data format
Tab delimited format can be selected via the analyzer control panel, or through the RS-232 interface in
Standard Access level. Tab delimited data is presented in static columns (the same number of columns
is always transmitted in a complete data message). Column headings from left to right: Time since last
re-boot tab | Mode tab | O2 Concentration tab | Alarm-1 status tab | Alarm-2 status tab | list of Fault codes
active tab. For detailed information on data formats, please contact the Neutronics Service Department.
4.1.2.5 Advanced Level 1 access
Advanced Level-1 access is the computer-interfaced user Setup mode. Access to Advanced Level-1 can
be accomplished on a PC by typing “setup” when viewing the Human Readable ASCII output. The User
