3.5 TARGET COMMUNICATION CONNECTIONS
There are two driver boards available to closely match most application requirements.
The standard driver board can be used to connect to the myriad of demo boards and
applications that contain the RJ11 connector. The high-speed driver/receiver board
combination can be used for high-speed communications, for additional trace features,
for large (several feet) emulator-to-target distances and for noisy environments.
3.5.1 Standard Connector
Using the standard driver board, the MPLAB REAL ICE in-circuit emulator is connected
to the target device with the modular interface (six-conductor) cable. The pin number-
ing for the connector is shown from the bottom of the target PC board in Figure 3-6.

3.5.2 High-Speed/LVDS Connector
Using the high-speed driver/receiver board combination, the MPLAB REAL ICE in-cir-
cuit emulator is connected to the target device with an 8-pin interface. The pin number-
ing for the connector is shown from the top of the target PC board in Figure 3-7.
FIGURE 3-7: HIGH-SPEED CONNECTION AT TARGET
Note: Cable connections at the emulator and target are mirror images of each
other, i.e., pin 1 on one end of the cable is connected to pin 6 on the other
end of the cable. See Section 12.5.2.1 “Modular Cable Specification”.
