ROGRAMMING
Each approach has its advantages and disadvantages. You may prefer one approach and use it often, but you may
occasionally need to use an alternative approach.

DET phone
PC-DBA laptop

Advantages
• You do not need a laptop PC
to program the database.
• The phone is a direct
interface to the CPU, so
there is no chance of
database corruption during
transmission. If you are
having a unidentifiable or
persistent problem, use DET
phone programming to
eliminate the possibility of a
corrupt database.
• You can save the existing
database residing on the
switch via a RECEIVE ALL
command. When you need
to modify the database, you
can use the switch version as
a basis so you will not have
to reprogram all its custom
settings.
• If you lose the switch
database because of battery
failure or because you must
perform a Master Clear, you
will NOT have to
completely reprogram the
database (provided you have
previously saved a copy of
the custom switch database
onto your laptop).
Disadvantages
• You have a limited visual
interface (the phone display)
vs. a menu screen.
• You have to do all
programming on site.
• DET phone programming
can take longer to perform
than PC-DBA
programming.
• You cannot save the current
switch database. If you lose
this database because of
battery failure or because
you have to perform a
Master Clear, you will have
to completely reprogram the
database.
• You need a laptop with a
serial port.
• You do all programming on
site.
• PC-DBA is not a direct
interface to the CPU.
Therefore, the possibility
exists that a corruption can
occur when transmitting the
laptop database to the
switch.
• You must be diligent in
performing a RECEIVE
ALL when first arriving on
the customer site, and prior
to modifying their database.
If you neglect to do so, you
may inadvertently perform a
SEND ALL first, thus
writing over their custom
programmed database with
whatever database you last
used on the laptop.
