ABOUT 6FX1113-0AE02 :
The communication board CS21 is the new version of the CS2 board. The board is designed, in
conjunction with the communication board CS11, to link from two to four board racks SR1 or SR5 of
the Simadyn D system. Therefore a fast parallel link is possible via the C-bus. The data transfer can
therefore only be carried out by processor boards with a C-bus connection (PM12, PM13, PM16).
The CS21 board contains the driver which switches the addresses, data and control signals on the
CS11 board memory.
A daisy chain arbitration is enforced between the communication boards CS11 and CS21 in order to
prevent accessing to the dual port RAM by more than one rack. A permanent request signal may be
generated in order to transmit several data blocks successively. No other processor board is
permitted access to the dual port RAM while this signal is set.
The rack containing the CS21 board is designated the slave in the system. The basic clock rate, the
time clock interrupt and the external interrupt are received from the CS11. Therefore this rack can be
synchronized by the master rack.
The memory area of the dual port RAM lies within the special peripheral area (40000H - 6FFFFH).
The start address is defined by the compiler. Accessing the chip select logic and the memory is
carried out via a programmable address decoder (PAD).
The connection between the boards CS11 and CS21 is made via a 50 pin cable. The control signals,
addresses and data are transferred via differential bus drivers and receivers in order to improve
security against signal corruption.
