Revision B 120 Series Maternal/Fetal Monitor 11-7
2015590-001
Peripheral Devices: DINAMAP Models 1846, 1846SX, and 1846SX/Oxytrack, 8100, and 8100T
DINAMAP Models 1846, 1846SX, and 1846SX/
Oxytrack, 8100, and 8100T
All of the above DINAMAP monitors can be interfaced to a 120 Series Monitor to
provide a printout of NBP values on the strip chart paper; the Models 1846SX/
Oxytrack also provides a printout of the MSpO
2
values on the 120 Series Monitor
strip chart as well.
1. Refer to Table 11-1 for the appropriate interface cable. Connect one end to an
available RS-232C port (J109, J110, or J111) on the 120 Series Monitor;
connect the other end to the serial communications port on the pulse oximeter.
Refer to the Critikon documentation for information on the name of the
connector.
2. Access the Communications Setup service mode screen and set the baud rate
and mode for the appropriate port to 600 and CRITIKON, respectively; then
exit the service mode screens.
3. Access the General Setup screen and choose the time interval for printing the
MSpO
2
values on the strip chart paper. Refer to “Chapter 5, Setup Procedures” ,
in this manual for more detailed information.
4. Be aware of the following information specific to DINAMAP monitors:
‹
The clock on the Critikon Models 1846, 1846SX, and 1846SX/Oxytrack
must be set to within 10 minutes of the 120 Series Monitor. If the clocks
are
not within 10 minutes of each other, the time will print with each blood
pressure reading.
‹ The clock on the Models 8100 and 8100T is not a real-time clock. Instead,
the clock measures elapsed time since the monitor was turned on.
‹
Due to the storage capabilities of DINAMAP monitors, it is recommended
that power be cycled at the beginning of each data session. This ensures
that any previously stored data is cleared.
‹ When using STAT mode on a DINAMAP monitor, the 120 Series Monitor
does not print the time with each reading due to overcrowding on the strip
chart. Instead the time is printed once every three to five minutes.
‹
The DINAMAP Model 1846SX discards NBP values after 90 minutes.
‹ The DINAMAP Model 1846SX/Oxytrack does not discard old NBP
values.
‹
The DINAMAP Model 1846SX/Oxytrack will omit the pulse rate with the
NBP reading if MSpO
2
is also in use. In other words, the pulse rate from
the MSpO
2
reading takes priority over the pulse rate from the NBP reading.
