Service Manual BSM-4100 4.7
ZB-800P interface and ECG/BP output circuits are provided on the board. These
circuits send out the analog signals with almost no delay. Especially, the ECG/BP
output circuit acquires ECG and BP analog signals from the ECG/RESP and multi-
parameter 1 sockets on the front panel. The ECG analog signal is directly sent to
the ECG/BP OUT socket without multiplexer. The BP analog signal is directly sent
to the ECG/BP OUT socket after the MP1 board receives the zeroing data from the
CPU on the DPU board. These analog signal outputs do not require any process
with CPUs on the MAIN board and CPU on the DPU board.
