f. Ethernet Interface Card
Note that the 670-0829-XX (PCB Assembly, Ethernet Interface) is used in the 90310 and the 90309-W.
The Ultraview 1030/1050 wireless monitor does not have the 670-0829-XX with the components
discussed below.
The 670-0829-XX PCBA has a 16-position rotary microswitch (also referred to as a "thumb wheel switch")
for channel selection. The switch is normally covered by a protective cap. Switch selections are made
using a small screwdriver.
There are two operating modes for a Wireless bedside: fixed channel and auto channel select.
Fixed channel Mode

Any switch position from 1 though F (not zero) will assign a specific, fixed channel number
to the 90310 or 90309-W. (On an Ultraview-1030/1050 the Radio configuration is set to a
non-zero value). The channel selection on the slave monitor and the WNI must be the same
for them to communicate. This limits the Wireless bedside to only one channel; even if a
valid master is in the area on a different channel, the Wireless bedside will never synch to it.
In the example illustrated here, channel C has been selected.
Auto-select Channel Mode

Setting the switch position to 0 allows a slave monitor to "roam". A WNI is never
set to Auto-
select. With this setting, the slave will change its channel to synchronize with any available
Master, choosing the first one with an acceptable signal. Monitors that move frequently, or
are used in transport situations, will be more likely to use auto channel select. Remember
that only 20 waveforms from slaves may synch with any given master. Allowing more then
20 waveforms to attach to a single WNI can cause data dropouts and failure to attach to the
WNI.
There are also 8 LED's on the edge of the 670-0829-XX PCBA that are viewable through a cutout just
above the thumb wheel switch. During power-on diagnostics, these LED's display the test numbers as the
self tests are performed. If a failure occurs, the LED’s will indicate which test failed. (Refer to the
90309/90309-W Service Manual, 070-0438-xx for diagnostic guidance). Note that the LED’s should only
go through the self-test sequence at power up; if this sequence occurs during normal operation, it may
indicate a hardware failure.
If the self tests complete successfully, all LED’s flash twice, the yellow (bottom) LED flashes to indicate
that the system is operational, and the four highest LED’s indicate the current thumb wheel switch
position in binary format. For example:
X
X
X
X
Thumbwheel
set to
channel 1.

Thumbwheel
set to

… and so on.
