keyboard by tapping the icon again. DO NOT USE THE “ENTER” KEY, as this will
cause the application to exit. Once all the new parameter values are entered,
hit the Set Parameters button to accept the changes. Parameters shown in
brackets, [ ], in the Current Device Settings window may not be changed. The
new values will appear in the Current Device Settings window.
To change Amp Mode, select an option, Low/Medium/High, from the pull-down
list. To change XmitPower, use the up/down arrows to the right of the field. To
uplink a sensor to a specific iCCU, enter the serial number of the iCCU in the
CCU field, or enter all zeros to broadcast to all iCCUs in listening range. The
Sync to PC option synchronizes the Real Time Clock on the device to the clock
on the PocketPC

. Use this option to synchronize all devices in the field to the
same clock. Normally, Day Begin and Day End are set to 12:00 AM. To change
these parameters, use the up/down arrows to the right of the field. These

The Current Device Settings window provides other valuable information that is
accessible using the scroll bar. Figure 3-11 below shows the Current Device
Settings window for an iTLM-1 when scrolled down to reveal additional
parameters. This other information includes:
• the device serial number;
• a 4-byte encryption key, called the cypher, which must be the same
for all devices in a network;
• the home channel that the device waits on when there is no activity,
(when active the device scans all channels, 0-52);
• the modulus through the scanning sequence, called the DSS skip,
that can create additional sequences and must be the same for all
devices in a network, (usually set to 1);
• the version number of the device’s firmware.
