Remarks
With BT220-1:
tive when you print out the diagnostic memory.
The BT220-1 in this case automatically changes the interface parameters.
After the printing process the parameters necessary for communication with
the PS 5000 (19200 bits/s; 8 data bits; even parity; 1 stop-bit) are set again.
Communication with a peripheral unit is only possible when
-
the connection cable is correctly wired (inc. any necessary Handshake
leads),
-
the interface parameter settings of both units are identical.
In the following description we assume that the BT220 is in the message dis-
play mode (see chapter 5.1, page 5-2).
