Control input
1 control input (KL8/ terminal 7 via optocoupler).
Presettable as programme change or event input.
... for programme change
Condition: Address 270 is set to "ext. signal".
A voltage of +7 to +27 Volt stops the actual programme (Adr.010) and
changes to the target programme (as preset in address 271).
0V (or open circuit) to +3 Volt returns system to the initial programme.
... as event input
Each positive signal edge initiates an immediate sample cycle. The condition
for this is that the selected active programme (as preset in address 010) is
set to "Event", (Setting up for programmes 1 to 6 is done in addresses 210,
220, 230, up to 260).
Interface (TTY
Primo-Bit)
To record sampling sequences and preset parameters.
Connect KL8/ terminal 8 (TXD) to pin 24 on the
Primo-Bit.
Connect KL8/ terminal 12 (+UTTY) to pin 17 on the
Primo-Bit.
