5.3.2 HeartScreen 80G-L Main board versions
There are two versions of the HeartScreen 80G-L Main board.
Important!
If you order the HS80G-L Main board as service part, make sure you order the same type!
One of the main differences is the design of the 50-pin ribbon cable ensuring the connection with the Interface Board:
•
One is a standard 1.27mm division width, conventional hole-mounted design (the HS80G-L Main Board
identifier A-1032-2).
•
The other contains a double density, 0.635mm division width ribbon cable assembled with SMD connectors
(the HS80G-L Main Board identifier R-1924-0).
It is also important that the transmitted signal order on the cables is different. The following schematic parts indicate
the two cables’ signal line orders:
A-1032-2: R-1924-0:
The other main difference is the test connection placement and design. The two designs and placements according to
HS80G-L Main Board identifiers are:
A-1032-2: R-1924-0:
The connection and schematic diagrams referenced in the service documents are for the R-1924-0 board.
