Test Box.

The Test Box allows the user to test Remote and Controller batteries under load
as well as test Remote Arm/Fire functions, and test Remote receivers. The Test
Box also serves as the programming interface between a computer and a RFD
Unit.

TEST BOX DESCRIPTIONS.

Antenna / Battery Charger Connector:

The Test Box has an Antenna/Battery Charger connector like the Remotes and
Controller. Installing an antenna from the system onto the antenna connector
turns on the Test Box. The Test Box has an internal battery pack that must be
recharged using the system battery charger.

Probe:

166x Series Test Box

12/19/01 Ver 1.4

Battery Test - Standby

The Test Box has a probe that plugs into the Remote or Controller under test.
The Test box communicates to the Unit under test through the probe and by
using a radio transmitter that is internal to the Test Box. The two leads coming
off the probe are for connecting to the Remote binding posts. The firing voltage
of the Remote will be measured through these connections.

Serial Connection:

A serial cable connects the Test Box to a computer serial port operating at 1200
baud. The serial cable must be connected to a computer when the Test Box is
being used to program Controller and Remote Units. The serial cable may also
be used when the Test Box is in the test mode. While in the test mode, the Test
Box transmits the information displayed on the Test Box screen out the serial
cable. A terminal program such as Hyper Terminal may be set up to capture this
information to a file. The file can then be saved and printed.

TEST BOX OPERATION.

Test Box Messages

When the Test Box is turned on, the following message is displayed.

The “166x Series” part of the message

identifies the system types that the Test Box is designed to operate with.
“12/19/01” is the date of the Test Box firmware. “Ver 1.4” is the version of the

Test Box firmware.
Plugging the Test Box probe into the Test Box Antenna Connector puts the Test
Box into a self-test mode. In this mode, the Test Box loads its own internal
battery and then displays the loaded battery voltage along with the low battery
threshold point.
