Status Error (0x0002)

A Read returns the bit map for any error that is present after the application of fault stage time
delays. The following table shows the errors that are represented by each bit in the register.

3.4 Product Model (0x0004)

A read-only register returns the model type for the detector, a constant "5500" in decimal format.

3.5 Software Revision (0x0005)

A read returns the software revision of the Ultima OPIR-5 Detector in 2 ASCII characters. The most
significant byte is the first character, the least significant byte is the second character. For example,
if this register reads 0x2042 then the first digit is 0x20 (a space character) and the second is 0x42
(the character B). So in this example the firmware version is " B".

3.6 Percentage Beam Block (0x0006)

This register returns a value from 0-100. When the optical path of the Ultima OPIR-5 Detector is
clear, the reading is 0% blocked. When the register reads near 100 the optical path is blocked and
must be cleared immediately. At 100% the Ultima OPIR-5 Detector indicates a fault condition and is
no longer capable of detecting gas. This register can be used for predictive maintenance.
