HPP-100 Hand-Held Programmer
Revision 3.3 3
System Preparation
When using the Hand-Held Programmer, all system programming is done through the Master
Reader. Before using the Hand-Held Programmer, perform the following system preparation and
verification steps to ensure your system is fully operational and ready for programming.
Applying Power to the Master Control Unit
If power is being applied to the Master Control Unit for the first time, perform the following checks.
• Verify all power and network communication wiring is correctly and securely connected to the
control units.
• Verify all option boards are correctly and securely connected to the control units.
• Verify all control unit addresses are set correctly, with a unique address for each control unit.
• If the optional LCD display is used, verify it is correctly and securely connected to the Master
Option Board on the Master Control Unit.
Once these checks are complete, apply power to the system. After several seconds of operation,
the network will begin to communicate, and the Network Activity LED (in the upper left corner of
the Master Control Unit’s option board) will pulse in rapid bursts followed by a short pause. If the
LED does not pulse, the network is not communicating. Turn all system power off and review the
above checklist.
If the system has the optional LCD display installed, it will briefly display the following message
when power is applied.
OB-xxx
MASTER
The upper field displays type of option board connected and the lower field displays the mode of
operation (Master, APB Master, or Reader Number).
When the unit completes its power-up sequence, the following message appears and remains on
the LCD display. This is the “system at work” screen.
