36 • Using the DAS-1700 Series with DriverLINX
Digital Input Subsystem Signals
The Digital Input subsystem has one 4 or 8-bit digital input port and two control
inputs which DriverLINX models as 1-bit logical digital input ports. DriverLINX
maps these signals to Logical Channels as shown in the following table:
Port
4-bit digital input
External clock alias
External trigger alias
How DriverLINX maps digital input hardware channels to Logical Channels.
Digital Output Subsystem Signals
The Digital Output subsystem has a 4 or 8-bit digital output port and a group of
control signals that you can use as an output port. DriverLINX maps these signals to
Logical Channels as shown in the following tables:
Other Models
Port
4-bit digital output
5-bit digital output
How DriverLINX maps digital output hardware channels to Logical Channels of other models.
Counter/Timer Subsystem Signals
The Counter/Timer subsystem has one or two counter/timer channels for analog
input/output pacing. It also has an external clock source and a gate input that the
board can use with any Logical Channel. DriverLINX maps these signals as shown in
the following table:
Timer
Input Pacing Counter
Output Pacing Counter
(AO models only)
