Assembly.Outputs.ResetLines $G

Setting the I/O output lines.

.AutoEOD: The automatic output of the EOD (End of Determination) at the

end of the determination can be switched off. Thus, for example,

in conjunction with a Coulometer several determinations can be

performed in the same beaker. Before AutoEOD is switched on,

line 3 must be set to "OFF".

.SetLines: With $G, all lines are set.

.SetLines.LX: Set the line LX. "active" means setting of a static signal, "inac-

tive" means resetting of the signal, "pulse" means output of a

pulse of app. 150 ms, "OFF" means the line is not operated, see

also page 131.

Warnings:

If you have "AutoEOD" to "ON", an active line 3 is set to "inac-

tive" by the EOD pulse.

L6 is the line of the activate pulse. An active line 6 is set to "in-

active" by the activate pulse.

L5 is the error line. It is continuously controlled by the Coulom-

eter program and can therefore not be set freely.
