3.1.3 PROGRAMMING CABLES
The cables from the repeater to the computer are
not included.

3.1.4 EEPROM DATA STORAGE
The data programmed into the MPC is stored by
an EEPROM memory. Since this type of device is
nonvolatile, data is stored indefinitely without the
need for a constant power supply. A repeater can be
removed from the site or even stored indefinitely with-
out affecting programming. Since EEPROM memory
is also reprogrammable, a new device is not needed if
programming is changed.
3.1.5 GETTING STARTED
NOTE: Before starting you should already know
how to start Windows NT
, format and make backup
copies of disks, copy and delete files, and run pro-
grams. If you are unfamiliar with any of these actions,
refer to the Windows NT manual for your computer for
more information (see Section 5).
Follow the computer instructions for loading the
disk. The computer needs to have RS-232C capabil-
ity, for example, the Serial Card in slot "COM1" or
"COM2".
The LTR-Net Programmer is used to configure
repeaters for proper operation with the LTR-Net
protocol.
From the repeater standpoint, an LTR-Net system
consists of one or more repeaters installed in a Local-
ity, a 3000 Series Switch and the necessary intercon-
nects and programming to provide LTR-Net operation
(see Section 1).
The LTR-Net Programmer defaults to using
COM1 at 9600 baud to communicate with a repeater,
however this can be changed by selecting Utilities ->
COM Port Setup from the menu, or by clicking on the
COM toolbar button (see Section 4.7.1).
When you first start the programmer, you should
create a Locality file with the information you wish to
program into repeaters at that Locality. See "How Do
I ... Create A New Locality File" for information on
performing this function.
NOTE: All repeaters installed in a given Locality use
the same Locality information, but each has its unique
repeater information programmed.
3.1.6 LIMITATIONS
The LTR-Net Programmer requires Windows NT
4.0 or later, or Windows 95 or later.
In order to read data from a repeater, a Locality
file must first be loaded from disk, or create and save
a Locality file. Only one Locality file may be loaded
at a time.
The LTR-Net Programmer supports COM1
through COM4, and all of the baud rates currently
supported by the MPC. Since the number of data bits,
stop bits, and the parity are fixed in the MPC, these
cannot be changed in the programmer.
