■ Operating conditions
EthernetBlaster
Hardware
Connections
The EthernetBlaster cable connects to an Ethernet cable with a RJ45 jack
to a 10/100Base-T Ethernet hub/switch (via a straight 8-wire data cable)
or a 10/100Base-T Ethernet port of a PC (via a crossover data cable).
Depending on your connection (remote or direct), data is downloaded
through the EthernetBlaster communications cable to the circuit board
via the connections discussed in this section.
Voltage Requirements
The EthernetBlaster VCC(TARGET) pin must be connected to a specific
voltage for the device being programmed. Connect pull-up resistors to
the same power supply as the EthernetBlaster V
CC(TARGET).
See Table 3–1.
