Software Version Display
After the Model 5130’s power-up sequence
has completed, some of the unit’s LEDs are
used to automatically display the software
version number. This is useful when work-
ing with factory personnel on application
support and troubleshooting situations. The
five LEDs associated with the channel 1
FROM audio level meter are used to display
the major release number with a range of
1 through 5. The five LEDs associated with
the channel 2 FROM audio level meter are
used to display the release sub-number
which ranges from 0 to 5. (No lit channel 2
LEDs indicates sub-number 0.) The soft-
ware version number will display for ap-
proximately one second after the power-up
sequence has completed but before normal
operation begins. Refer to Figure 6 for a de-
tailed view of the LEDs and the correspond-
ing software version numbering scheme.
Note that while it’s easy to determine
which software version is loaded into
the Model 5130 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 5130’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.
