g. OEM radio card
There are two types of OEM radio cards used in the Spacelabs wireless ethernet system, one for U.S.
and one for European use. Both cards are identical in form, fit and function; only the filtering circuitry is
different.
Part number 010-0914-xx is for use in the US only. There are two versions of this card:
Proxim Radio card 010-0914-04 -- may use software version 1.57m or 1.8B
Proxim Radio card 010-0914-05 -- requires the use of software version 1.8eB
The 010-0914-04 can be easily recognized because it has three metal RF shields on the card. There is a
single, larger RF shield on the 010-0914-05 radio card (see picture below). The version of radio software
is printed on the label on the software EPROM.

• Software level 1.8 is available for both radio cards 010-0914-04 and 010-0914-05, but the specific
version is 1.8B for the -04
and 1.8eB for the -05. The 010-0914-04 can have either 1.8B or
1.57m but cannot
use 1.57 (with no m) or 1.8eB. The 010-0914-05 can only use 1.8eB. A radio
card with the wrong version will work, but will have poor communications (visible as waveform
gaps or dropouts) at distance or on loaded networks.
• ALL Masters must contain version 1.8eB if ANY node is at software version 1.8x.
The other type of radio card, part number 010-0940-00, has enhanced circuitry to meet the more stringent
European RF signal requirements and is called the "ETSI" OEM radio card. This card is NOT used with
U.S. installations.
All three cards have a transmitting frequency range of 2.4 GHz to 2.4835 GHz with a transmitting power
measured at the antenna of 100 milliwatts. The radio functions as a "frequency hopper" and by definition
will "hop" between a preset range of frequencies and will spend less than 200 ms on each frequency
before moving on to the next. The frequency hop sequence will vary depending on the thumb wheel
channel selected, or the channel selected in the Network Setup, Radio Setup menu with the wireless
90367 / 90369 monitors.
