Selection List for Over-the-Air Firmware Changes
Select the individual devices or groups of devices you wish to reprogram and then select
OK. Changing the firmware does not
change the configuration memory.
NOTE
The firmware will be changed the next time the DCM-200 communicates with DC-2000.
For instance, if the unit is not scheduled to call in for 24 hours, it will take that long to
update the firmware.
NOTE
When the firmware is changed the DCM-200 will be reset. See Chapter-7 for a
description of the unit’s behavior after a reset.
As a final note, you will notice in Figure 5-9 that the devices have phone numbers
associated with them. These are the numbers that can be used to “page” the DCM-
200’s. This information comes from the database for each device. Earlier in Chapter-
4 we discussed the ability of the DCM-200 to read the unit’s phone number from the
SIM card and report it to DC-2000. DC-2000 then automatically inserts this phone
number into the database. If the SIM card does not contain a phone number, it will
have to be entered manually. Review Chapter-4 and check with your cellular service
provider about programming the phone number into the SIM card. It could save you
a lot of work.
