Communications Cable

Specifications

OverviewEthernetBlasterHardwareConnections

This chapter provides comprehensive information about the EthernetBlaster communications cable, including the following:

■EthernetBlaster hardware connections

■Operating conditions

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 VCC(TARGET). See Table 3–1.
