Installation

It is recommended that a DRL2A Cold Start-up be performed when the unit is updated with a new program version. Refer to

Operating Mode Section 3.0 (DRL2A Cold Start-up and Changing The Line Card Number) for information.

After the cold start-up, check the configuration information listed in the Quick Reference Guide to make any required changes

for your particular application.

DRL2A Controls

Each DRL2A Module features 2 line cards. The LEDs and push buttons on the left side and the upper LCD are for Line Card

1. The LEDs and push buttons on the right side and the lower LCD are for Line Card 2.

Momentarily depressing and releasing a button will register as a single input or keystroke. Pressing and holding a button for

approximately 1 second will register as a repeating input or keystroke. For example, to quickly scroll through a list of items,

you press and hold the appropriate button, rather than pressing the button repetitively.
