SERVICE MODE DETAILED DESCRIPTION
Technical Manual
2.2 Instrument MUX related service modes
n 19 Show software version of IMUX CPU (n.nn software version)
This is the software version of the embedded software inside the IMUX CPU EEPROM. This
software can be updated on the field.
n 20 Show instrument holder & AUX-input signals (¦ ¦¦¦¦¦
signal)
This service mode is convenient for checking the proper operation of the doriot arm sensors
(on the IMUX PCB). The 5 rightmost segments represent the 5 instrument positions, from
right to left respectively. A short vertical bar indicated that the instrument is in the holder, a
long vertical bar that it is taken out from the holder. The leftmost vertical bar shows the signal
at the AUX input terminal on the IMUX PCB (6th instrument place).
n 21 Show active instrument hose ID-code (---- or nn ID-code)
This mode is convenient for checking the instrument hose ID-code and the related electronics
on the IMUX PCB. The code range is 1 to 26.
The display shows four dashes (----) if no instrument is selected. Activate a properly attached
instrument hose (in this same location) to display the ID-code. The code displayed should be
the same as indicated by the last digit(s) on the label on the quick connector.
n 22 Show active instrument hose identification signal (nnn
signal)
This service mode is similar to the one above. This mode shows the actual signal measured
from the identification pins on the instrument hose quick connector. The signal range is 0 to
510.
The display should show 223 to 228 when no instrument is selected (the electronics meas-
ures a local reference signal). If the signal is outside this range then there is an error on the
IMUX PCB. Check for any water leakage.
Activate a properly attached instrument hose (in this same location) to display the identifica-
tion signal.
n 23 Show active instrument switch/sensor signal (---- or nnn
signal)
This service mode shows the instrument (optional) switch or sensor input signal. The display
shows four dashes (----) if no instrument is selected. The display range is 0 to 255.
Activate a properly attached instrument hose (in this same location) to display the ID-code.
n 24 Show console syringe location hose ID-code (nn ID-code)
This service mode shows the hose ID-code for the hose connected to the syringe location.
The display shows zero (0) if no hose is attached, otherwise the hose ID-code is displayed
continuously.
