b. 90309 Option "W" (Bedside or Slave)
The PC Ranger (90309-W) is a PC Scout bedside/transport monitor with added wireless communications
capability. The PC Ranger includes an extended rear panel containing the I/O Bay board (670-0623-xx),
with an attached ethernet Interface board (670-0829-xx) in a slave configuration, a Proxim Radio card
(010-0914-xx), and a dipole whip antenna. The Bedside (Slave) has two way communications with the
90310 Wireless Network Interface (WNI) "Master" (described in following paragraphs) using a 2.4 GHz to
2.485 GHz frequency-hopping radio link.
Waveforms, alarms, bed information, and configuration
messages are transmitted from the slave to the network via
the master. Network and configuration messages are sent
from the master to the slave or from slave to master. WITH
THE
WIRELESS NETWORK SOFTWARE VERSION 2.03.06 OR
HIGHER AND
RADIO FIRMWARE VERSION 1.57 OR HIGHER, BED TO
BED COMMUNICATION IS ALLOWED
; WITH OPTIONAL INTERACTIVE
NETWORK
, FULL BED TO BED ACCESS TO BEDSIDE MONITOR
MENUS IS POSSIBLE
. THIS CAPABILITY ALSO INCLUDES ACCESS TO
HARDWIRE MONITORS

c. UCW – Z, 90367 and 90369 Option "Z" (Bedside or
Slave)
The Ultraview 1030/1050 option Z (Wireless option) contains a built-in wireless unit similar to the external
wireless unit on the PC Ranger Monitor. The basic difference between the Ranger and the Ultraview
1030/1050 is that the Ultraview 1030/1050 does not
contain a 670-0829-XX ETHERNET INTERFACE
card. The 90367/90369 imbeds the control functions of the 670-0829-XX card into the monitor’s main
board, and the 010-0914-XX OEM radio card is connected directly to the main board. Additionally the
Ultraview 1030/1050 supports five outbound parameters and enhanced site survey functionality. The
UCW option Z utilizes a 90310-C WNI which has been configured as a “slave”. This WNI communicates
through the ethernet port of the UCW.
d. 90310 Option "A", "B", or “C” (Master, or Slave interface unit)
The Spacelabs Medical 90310 is unique to the wireless network. The 90310/Master/WNI (Wireless
Network Interface) uses a modified 90485
module housing (see illustration at left) and
a standard 90486 power supply combined
with the 670-0829-XX PCBA (mounted
internally from the rear of the module
housing) and the 010-0914-XX OEM radio
card. For purpose of this document, the
"Master", "WNI", and the "90310" have the
same meaning, except for the 90310-C,
which is a Slave. The “Master” coordinates
the communication with the “Slaves” on the
same channel by controlling the frequency
hopping pattern. Slave monitors synchronize
with the master’s frequency hopping pattern,
allowing continuous communication. The
frequency-hopping pattern is dictated by the
selected WNI “channel”. Therefore, the
channel is not a specific frequency, but a
pre-defined sequence of frequencies.
