Powerful Software

Introduction 1-4
The 1256 provides extensive software capabilities, including:
•
Exclude Lists. Allows you to prevent simultaneous closure
of switches in a specified group. The switches are then
mutually exclusive.
•
Equate Lists. Reduces programming effort. When two or
more modules are on an equate list, they respond
simultaneously to a command sent to any of them.
•
External Trigger Input. Allows an external device to trigger
switching operations. The external device connects to the
External Trigger In connector.
•
External Trigger Output. Provides a pulse on the External
Trigger Out connector to trigger an external device, such as
a DMM, after the relay states have changed.
•
Scan Lists. Allows you to specify a sequence of relay
closures to step through in response to an external trigger
source. A scan list may include relays on one module or
multiple modules.
•
Programmable Delay. Allows you to specify the amount of
time delay from a relay state change to an external trigger
pulse.
•
Verification. Allows you to verify the status of all switches.
•
Path-Level Switching.

•
Power-Up Recall. Automatically recalls a complete
switching system configuration from non-volatile memory at
power-up.
•
Self-Test. Ensures that critical system components are
functioning correctly. This test executes automatically at
power-up.
