3 JTAG Boundary Scan Cable
The UM232H USB-to-serial adapter must be connected to the JTAG port on the DLP LightCrafter 4500.
Connecting the two devices requires the use of a Molex 51021-0600 connector. The user can either
directly connect the header pins on the UM232H to the cable or create a board to host the UM232H. The
required pin connections are shown in
Table 1 and Figure 1 .
NOTE: Two separate pairs of pins must be connected together to supply power to the UM232H from
the computer's USB port.
