Digital I/O
The input and output signals for the PCI-ADC parallel ports and counter/timers
are strictly digital TTL levels with voltage limits of zero volts for a logic low
and +5 volts for a logic high. Voltages outside these limits may cause damage
to the card. The output current drive capability makes the card suitable for
connection to TTL logic type circuits. The PCI-ADC is compatible with most
types of TTL logic. Because the lines are TTL it is recommended that input
signal lines do not exceed 2 metres in length. Operation at longer lengths may
cause drive level problems.
Driving conventional relay coils is not recommended without external
protection even if the coil current required is less than the PCI-ADC can
provide. Relay coils are inductive and as such can generate large flyback
voltages when de-energised which will destroy the device outputs.
Counter / Timers
Input signals to two of the counter / timers may be taken from the I/O connector
by sacrificing two bits of one of the I/O ports and configuring them as inputs.
The counter timer inputs are then driven from these I/O lines through 270 ohm
series protection resistors. The counter / timers are permanently enabled.
