  • Page 4: What Is Chipper Check Ii (Ccii)

    What is Chipper Check II (CCII)? Chipper Check II is an advanced interface box that provides communication between the TV set being serviced and a personal computer. The interface converts the I C bus communication of the TV to serial communication used by the PC. With the Chipper Check software, the PC is able to control certain functions of the TV and perform some alignments.

  • Page 5: Chipper Check Ii Interface

    The new interface CCII and a modified CC incorporates the tri-level logic circuit and are backwards compatible. Chipper Check II Interface There are two types of interface boxes, the modified CF002 and CF003. A tri-level interface is the only one that is compatible with current chassis.
  • Page 6 The PS2 cable is connected between the interface box and adapter board. There are 3 adapter boards; two legacy adapters and one TECI1. The TECI1 board has many plugs and a switch. These plugs are for connecting different cables for the different chassis.
