Section 5
Installation and Set-Up
The Model U-1400 detector has no DIP switches or jumpers to configure. In order for the detector to operate, the
external EEPROM memory module shipped with the detector
MUST
be connected to the DB-15 Aux Port
connector on the front panel. Connect an appropriately wired harness to the 55 pin Primary Interface Connector on
the front panel and apply power to the detector. If the detector is not new from the factory, it may be advantageous
to reset the detector back to the factory defaults to avoid having to check every setting for every loop input
channel. To reset the detector to factory default, press all four pushbutton switches simultaneously for five
seconds. When all four pushbuttons are depressed, the display will start counting down from five (5). When the
countdown reaches zero (0), releasing the pushbuttons will reload the factory defaults and reset all loop input
channels. NOTE: Resetting the detector to factory default settings will clear any previously mapped output(s).
All operating parameters can be adjusted from the front panel. The detector continues to operate normally while it
is in the Program Mode. The value currently displayed is always the actual value being used. Example: If you are
changing the delay time, the time displayed at the instant that a vehicle entered the detection zone for that loop
input channel would be the value used for the delay timer.
Pressing the
FUNC
pushbutton enters the Program Mode. The
FUNC
pushbutton has an auto repeat function.
This allows quick navigation to the desired parameter. The
FUNC
pushbutton only moves forward through all of
the parameters. There is no way to move backwards through the parameters.
While viewing any parameter, pressing the
CHAN
pushbutton will display the same parameter in the next loop
input channel. The currently selected channel is indicated at the bottom of the LCD display. Pressing and holding
the
CHAN
pushbutton for one second will exit the Program Mode and return to the Normal Mode.
To change any detector setting, the password protection feature must be disabled. When viewing a setting, press
the
(UP) or
(DOWN) pushbutton to enter password entry mode. The LCD will display
PSd
to provide an
indication that a valid password must be entered before any detector setting can be changed. NOTE: Pressing the
CHAN
button for two seconds at any time will exit password entry mode. Press the
(UP) or
(DOWN)
pushbutton. The LCD display will change to
000
with the leftmost
0
flashing. Press the
(DOWN) pushbutton
to change the flashing digit to
9
. Press the
CHAN
pushbutton a second time to get the center
0
to flash. Press the
(UP) pushbutton to change the flashing digit to
1
. Press the
CHAN
pushbutton a third time to get the rightmost
0
to flash. Press the
(UP) pushbutton to change the flashing digit to
1
. Press the
FUNC
pushbutton to enter the
password. Detector settings can now be changed. Press the
FUNC
pushbutton to enter the password. Detector
settings can now be changed. Password protection can be re-enabled by pressing and holding the
CHAN
pushbutton for two seconds followed by pressing the
(UP) pushbutton twice. If no action is taken to re-enable
the password protection feature, it will be automatically re-enabled 15 minutes after changing any detector setting.
Pressing and holding either the
(UP) or
(DOWN) pushbutton will cause the value to change rapidly until the
pushbutton is released.
U-1400 Mounting Instructions
The Model U-1400 is shipped with two mounting brackets and six 10-
32 x 3/8˝ pan head machine screws that can
be used to mount the detector to a shelf or a wall. The left and right sides of the U-1400 each have three 10-32
threaded inserts that are used to secure the mounting brackets to the sides of the unit.
