Power-Up Sequence

With the LDT-5500B Series Temperature Controller connected to an AC power
source, pressing the POWER switch will supply power to the instrument and start
the power up sequence.
During the power-up sequence, the following takes place.
For two seconds, all indicators light up, and all of the 7-segment displays indicate
"8". All lamps are then turned off for two seconds. Next, two versions of firmware
are displayed on the front panel: first version number displayed is mainboard, the
second is the front panel. After this, the sensor positions is displayed for two
seconds. After the power-up sequence, the unit is configured to the state it was in
when the power was last shut off (except for the display mode which defaults to
the control mode).

The LDT-5500B may be controlled by PC using USB. The USB Type B connector
is located on the rear panel above the sensor select switch. See the figure below.
Please install the USB driver from the CD included in the shipping kit prior to
