CPU Section
The processor is an 8051 derivative which contains a number of enhancements over the standard
8051, including an on-board 10 bit ADC. For most applications this degree of resolution is more
than adequate.
The data memory is in the form of a single package which contains the memory device with real
time clock (RTC) and integral lithium battery. This package has guaranteed memory retention of 10
years, and when flat the whole package must be replaced.
The program memory may reside in either a 64kB EPROM or the Expansion EPROM package
labelled as U5 (refer to the PCB overlay). When the program has been put into U5, it will be
labelled with the application WA number, otherwise it will be labelled with an ID number. When it is
labelled with a WA number, there must be no EPROM loaded in location U8 otherwise damage to
the processor circuitry will result. The Expansion EPROM package must only be removed using the
correct extraction tool otherwise either the package or the socket may be damaged.
The high capacity Flash memory has been added to the 1550 to contain three main blocks of
information, being Load-charts, Load Moment (LM) calibration tables and Data-logging. The
memory is contained in two plug-in SIMM cards and depending on the application, any number of
these may be installed. Refer to the relevant software configuration sheets for more details.
The SIMM cards can only be inserted one way, however care must be take during installation and
removal. It is essential that the SIMM cards are installed in the correct sockets and that the correct
sequence is followed.
To install a SIMM card, simply push the card into the socket at an angle of approximately 45
degrees (with the components facing toward the centre of the main circuit board). Once the gold
pads on the leading edge of the card have entered the socket, gently push the card into the socket
while rotating it to a vertical position. Installation is complete when the retaining clips on each end
of the socket have captured the edges of the board and have fully returned to their original position.
To remove a SIMM card simply push the retaining clips at each end of the socket outwards until the
SIMM card springs away from its vertical position. The card can then be gently withdrawn from the
socket.
