The Controller Board
The components of the controller board are listed below.
•
LEDs
—Used for a quick visual check on the status of various power
supplies, solenoids, and certain logic signals.
•
Connectors
— Route control signals to optics, microswitch, motors,
solenoids, and other components of the handler.
•
Pico fuses
—12 for the stepper motors (two per stepper driver circuit
and four for the traverse motor) and 24 for the dot matrix print head
wires (one fuse for each wire in the print head). Refer to the
schematic in Appendix C for the location of the pico fuses associated
with each motor.
The components of the controller board supply the following:
• Signals to activate the solenoids, the motors, and the labeler wires
• Control signals for the two RS-232C ports and the handler port
• EPROM that contains the handler system firmware
• EEPROM that stores nonvolatile handler parameters
• Circuitry for the optics, the display, and the keyboard
• Microprocessor and kernel logic control
Refer to Appendix C for the controller board schematic and layout.
Power Supplies
Four power supply assemblies are located in the body of the 2500. See
Figure 5-4. These supplies operate off the handler’s single AC input.

Dot Matrix Label
Printer
The dot matrix label printer (also simply referred to as labeler) uses a
2 x 12-wire, in-line dot matrix print head to print labels. The labels are on
a roll of label liner that is threaded through the labeler assembly from a
label supply reel. The labeler can print a maximum of three lines of text
on a label.
The label drive motor is the second motor mounted behind the labeler
assembly plate. It provides the drive to turn two rollers that advance the
liner through the labeler system. The black pinch roller snaps into
position to assist the label advance roller to get a firm grip on the label
liner. The timing of the label advance roller has to be precise so it can
accurately place the label on the device and ensure even spacing between
the printed characters on the label.
The 2500 lets you choose the position of the label on the device. In order
to accomplish this, the labeler must know the location of the labels on the
liner and must be able to advance the label so it contacts the device at the
correct time. On the front of the labeler assembly plate, the ADC optic
roller assembly detects the leading edge of the label. The highly sensitive
ADC optic emitter/collector pair reads the level of light that passes
through the combined label and liner during label calibration. This light
reading, called the ADC optic value, is the reference used to compare to
the higher level of light detected when only the liner passes through the
optic. This reading allows the labeler to synchronize to the leading edge
of the labels.
Character Sizes
The labeler can produce six font sizes, measured in characters per inch
(CPI). The six font sizes are listed below.
• Normal Fonts: 18, 20, and 26 CPI
• Short Font: 26 CPI
• Tall Fonts: 12, 16
