3 Using the Bus SAT/IN
Module
This chapter describes the recommended powerup procedure for the Bus SAT/IN module.
It also discusses how to configure the Bus SAT/IN module from Millennium software, as
well as how to troubleshoot the Bus SAT/IN module.
3.1 Powerup
When all connections are made, power up detectors and any devices connected to the
external event terminals. Refer to the installation guides for each device for powerup
procedures.
You connect the Bus SAT/IN power supply to a wall outlet or power strip.
Attention:
The Bus SAT/IN module and the power supply both do not have an ON/OFF
switch. Always disconnect the power cord at either the wall outlet or the power supply
before attaching or removing the 5-pin connector at the Bus SAT/IN module (see
Section 2.6, Connecting Power Supply.). Failure to do so may damage the unit.
Once the 5-pin connector is attached to the Bus SAT/IN module, do not remove it except to
service the module.
Bus SAT/IN module self tests
During powerup, the Bus SAT/IN module performs a series of self tests. During the
self-test sequence:
• Channel 1 and Channel 2 LEDs (Light Emitting Diodes) flash once.
• OK LED remains illuminated.
Successful powerup
If the powerup sequence is successful, the OK LED remains lit.
Powerup problems
If the OK LED does not light, check the Bus SAT/IN power supply connections.
