Party-Line Interface Module
Software Version Display
After the Model 5132’s power-up sequence
has completed, some of the unit’s LEDs
are used to automatically display the soft-
ware version number. This is useful when
working with factory personnel on applica-
tion support and troubleshooting situations.
The five LEDs associated with the Ch1
(Pin 2) From audio level meter are used
to display the major version number with
a range of 1 through 5. The five LEDs as-
sociated with the Ch2 (Pin 3) From audio
level meter are used to display the version
sub-number which ranges from 0 to 5. (No
lit channel 2 LEDs indicates sub-number
0.) The software version number will dis-
play for approximately one second after
the power-up sequence has completed but
before normal operation begins. Refer to
Figure 6 for a detailed view of the LEDs
and the corresponding software version
numbering scheme.
Figure 6. Detail of front panel showing the level meter
LEDs that display the software version. In this example,
the software version is 4.2.
Version Sub-Number
Major Version Number ( No LED lit indicates .0)

 4 .4 O
O 3 .3 O
O 2 .2 
O 1 .1 O
Note that while it’s easy to determine
which software version is loaded into
the Model 5132 a trip back to the fac-
tory is required to update it. The 8-bit
microcontroller that provides the unit’s
logic “horsepower” also includes internal
FLASH memory. This non-volatile memory
is used to store the operating software
(“firmware”). Re-programming this memory
requires using a specialized programming
unit. While not outrageous in price, it still
costs in the range of US$500. The pro-
grammer uses a ribbon cable and socket
to interface with a 6-pin header on one of
the Model 5132’s printed circuit boards.
And, as you would guess, once connected,
reprogramming takes only a matter of sec-
onds. But unfortunately the programmer
is not something that would be found in
a typical “field shop” or repair facility.
