Overview
This chapter provides comprehensive information about the EthernetBlaster
communications cable, including the following:
■ EthernetBlaster Hardware Connections
■ 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 V
CC(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).
