Step 8. RF Network
Two options exist for using an RF network.
• Option A: Use your existing RF network.
• Option B: Set up a simple RF network using a WS2000. For details, see Appendix E, Self Contained
Pre-Built Demo ( Step 5. Configure the RF Hardware on page E-5 ).
The CA50 scans for access point transmissions on the RF channels specified for the country in which it is
used. In the Americas, when the 802.11b/g radio is enabled the CA50 defaults to scanning the three
non-overlapping radio channels 1, 6 and 11, which correspond to frequencies 2412 Mhz, 2437 Mhz and 2462
Mhz respectively. When the 802.11a radio is enabled, the CA50 scans for access points on all the
country-appropriate channels in the 5.0Ghz range.
To designate specific channels to scan, a channel mask can be applied using the following registry keys where
Freq1, Freq2 and Freq3 correspond to standard 802.11 channel frequencies in Mhz.
[HKEY_LOCAL_MACHINE\Comm\JEDI10_1\PARMS]
"ChannelMask"="Freq1 Freq2 Freq3 …"
[HKEY_LOCAL_MACHINE\Comm\PW\JEDI10_1\PARMS]
"ChannelMask"=" Freq1 Freq2 Freq3 …"
In the following example, the frequencies refer to 802.11a channels 36, 40, 44 and 48. The registry keys limit
scanning to these channels.
[HKEY_LOCAL_MACHINE\Comm\JEDI10_1\PARMS]
"ChannelMask"="5180 5200 5220 5240"
[HKY_LOCAL_MACHINE\Comm\PW\JEDI10_1\PARMS]
"ChannelMask"="5180 5200 5220 5240"
Step 9. Use MSP 3.1 to Prepare CA50 Devices for Use
Use MSP 3.2.1 to prepare the CA50 devices for use.To generate Rapid Deployment bar codes to connect the
CA50 device to the wireless network and establish communication with the UCA server, ensure all settings (RF
wireless network settings, IP address of the UCA server, etc.) are at hand:
• ESSID = UCA
•
Encryption = None (Open)
• UCA Server IP= 192.168.0.253
•
Store #: 0002.
Prior to creating RD bar codes for the CA50, see Chapter 12, Staging and Deploying CA50s for detailed
information about MSP settings and MSP staging profiles, including:
•
CA50 Parameters Required to Generate RD Bar Codes on page 12-2
• UCA.settings.xml File for Configuring the UCA Client Application on page 12-2
NOTE Load MSP software using the MSP installation instructions.
IMPORTANT When installing MSP 3.2.1, the UCA settings screen includes a Language drop-down list. Select the
appropriate language to localize the CA50 device. The language selected must match the language
selected when installing UCA server software. If the language selections does not match, the UCA
server software language (selected during the UCA server software installation) the localization of
device happens after the user login.
