EMULATOR COMMUNICATIONS WITH THE PC AND TARGET
The MPLAB REAL ICE in-circuit emulator system consists of these items:
? Emulator pod with indicator lights, push buttons and a logic probe connector
? USB cable to connect a PC to the emulator pod and power the pod
? Driver board and modular cable(s) to connect the emulator pod to an ICE header
or target board

The emulator communicates with the PC and is powered through the USB cable.
The emulator communicates with the target through the configurations discussed in the
following sections.
CAUTION
Do not connect the hardware before installing the software and USB drivers. Also, do
not change hardware connections when the pod or target is powered.
2.3.1
Standard Communication
The emulator system can be configured to use standard communication for both
programming and debugging functions. This 6-pin connection is the same one used by
other Microchip in-circuit debuggers.
The standard driver board is plugged into the emulator pod to configure the system for
communication with the target. The modular cable can be either (1) inserted into a
matching socket at the target, where the target device is on the target board
(Figure 2-2), or (2) inserted into a standard adapter/header board combo (available as
a Processor Pak), which in then plugged into the target board (Figure 2-3).
Note:
Older header boards used a 6-pin (RJ-11) connector instead of an 8-pin
connector, so these headers may be connected directly to the emulator.
For more on standard communication, see Chapter 12. “Hardware Specification” .
