Host/Communication Connections
A mini-USB-to-USB certified cable and a standard DB9 male-to-female cable should
be used to connect the dsPICDEM™ MCHV Development System to the host
computer.
The communication port connectors are listed in Table 2-2. Refer to Figure 2-5 for their
exact location.

COMMUNICATION PORT CONNECTORS
2.3.2.1
CONNECTION SEQUENCE
The recommended connection sequence is listed below. The user should ensure that
the following sequence is met before connecting the system to the mains, a motor and
a host computer.
1. Connect the motor terminals R, Y, and B (also known as RWB or 123 or ABC) to
the connection nodes M1, M2, and M3 (4, 5, and 6 in Figure 2-5), respectively.
2. Follow the next steps if position sensors are utilized to control the motor. If not,
proceed to step 3.
a) If the motor position is sensed with Hall Sensors, connect the terminals A, B,
and C to the connection nodes HA, HB, and HC (7, 8, and 9 in Figure 2-5),
respectively. Also, connect the positive te5V to the connection node
+5V and the ground terminal to the connection node GND (10 and 11 in
Figure 2-5).
b) If the motor position is sensed with a Quadrature Encoder, connect the ter-
minals phase A, phase B, and Index to the connection nodes HA, HB, and
HC (7, 8, and 9 in Figure 2-5), respectively.

Note:
Before making any connection, verify that the system is not powered and it
is fully discharged. The system is completed discharged when the red LED
D13 is OFF.
