Id option appears on the menu. If you are using a Spectrum24 card
with the Spring protocol, the Net Id option appears on the menu.
Diversity
Determines how many antenna ports the radio will attempt to use for
communications. Match this setting to the number of antennas you’re using.
MU Sleep Mode
If you set MU Sleep Mode to On, the radio stays on even if an application
powers down the terminal because of inactivity. The default setting is On.
Boot Mode
Indicates the source of the terminal’s IP address. Options are Boot, DHCP or
Manual Entry. If you select Manual Entry, the terminal uses the IP address
specified in MU IP Address. See page
for more information.
Pwr Management If you set Pwr Management to PSP, the radio only powers up when there is
traffic on the network. If you set it to CAM, the radio is always ready to
receive. The default setting is PSP.
Buffers
Sets the number of data buffers used by the radio driver (4, 8 or 12).
ReXmit Delay
If a terminal tries to transmit a packet and fails, it tries to re-transmit the
packet later. ReXmit Delay sets the length of time between re-transmissions.
The options are short and long. The short option improves response time but
uses more power. If there is high network traffic, or a high amount of
electrical “noise” nearby, select short to improve response time.
Rate Control
Determines which Spectrum24 Access Points a terminal can communicate
with. The options are 1Mb only, 2Mb only, 1Mb and 2 Mb. Select a
parameter that matches the Rate Setting for the AP, if one has been specified.
For more information see Spectrum24 Wireless LAN Adapter Product
Reference Guide (p/n 70-20505-XX).
Scan/RF Op
Determines whether or not the scanner and radio can operate at the same
time. Concurrent Op allows both to operate at the same time. Scan Stops RF
causes the scanner to lock out the radio during an active scan.
Exit
Closes the utility and displays a DOS prompt.
