2.2.1
Light and Speaker Board
The Lights and Speaker board mates directly with the system controller. +24V DC power arrives from the
lower bay. The PCB features power regulators, an Audio amplifier, and a RGB Light driver.
2.2.2
USB Port Usage
Wi-Fi and Bluetooth USB dongles are two independent devices that are featured standard. As mentioned,
the third available port is a USB 3.0/2.0 connector that is for the EAS Sensor, covered next.
2.3
EAS Sensor
The TR4300 TX/RX transceiver is the electronics PCB system of a pulse-listen Electronic
Article Surveillance (EAS) detection system which utilizes targets that are applied to
merchandise. There are no jumpers on the TR4300. Like earlier “Evolve” main boards,
the TR4300 has an FPGA (field programmable gate array) with processor and memory
functions. There is a USB interface with the system controller. Metal Shields are equipped
(separate shields for Rx and Tx circuit sections). Check for tightness.
For the device to detect real alarm events and not trigger due to “phantoms,” the EAS
Sensor has electronic tuning and digital signal processing.
The tuning of the system is the Field Service Technician’s responsibility. The NEO
Installation Manual (CKP P/N 10078945) will provide instructions.
2.4
Remaining Hardware
The LED Board is a 24V DC / 60mA powered device with three individual LED colors
per LED. The varying voltages applied to the set of three LEDs will illuminate the overall
LED in the color of light to be produced. This control is achieved by the Light and
Speaker board, which gets the instructions from the controller where user settings can be
applied (i.e. change the default).
NEO also has a speaker which is quite different from earlier Checkpoint “Buzzers.”
(Piezoelectric transducers were formerly used, whereas this is a magnetically driven
voice-coil and pole-piece type loudspeaker.) It can play back an infinite range of acoustic
sounds. The frequency range is roughly 150 Hz to 20 kHz. More details on the audio
speaker are covered in Specifications below.
The wiring harnesses are all installed and tested at the time of manufacture.
Depending on application, the controller will utilize a different device than the standard
Wi-Fi antenna (USB device). At the time of installation or service visit for
reconfiguration, the Wi-Fi antenna can be replaced by a cell-modem module. There are 3
versions for FCC, EU and APAC specific regulatory approval. All devices provide the
same functionality of 4G LTE cellular data upload/download.
