USER'S GUIDE
3.1
Exploring the PK-232 Program
This chapter shows you how to use your PK-232 in each of its operating modes, describes
the keyboard commands you'll use to "talk" to your PK-232, and the answers, prompts and
error messages you'll receive from your PK-232.
3.2
LED STATUS and Mode Indicators
Your PK-232's front-panel LEDs show you the operating mode and system status at any mo-
ment. Each LED is marked with an abbreviated name. Some LEDs have two name markings.
All markings referring to Packet operation are below the LEDs. All other mode markings are
above the LEDs. Starting at the upper left corner, scan your PK-232's front-panel as we re-
view the LEDs and their meanings.
