2.7 Connecting to the Card
There are a total of seven connectors that can be used with the MC73110 Developer’s Kit card as follows:
Connector Name Function
J1 Power Provides operating power to the Developer’s Kit card.
J2 Motor feedback Inputs various motor-related signals.
J3 RS-485 Provides communication to/from the card when a
multi-drop RS485 is used.
J4 Motor Provides high voltage, high current connections to the
motor from the amplifier output.
J5 Remote switcher Inputs and outputs various signals for use with a
remote switching block.
J6 Host Inputs and outputs various non-motor command and
feedback signals to/from the Developer’s Kit card.
J7 Serial port Provides RS-232 communication to/from the card using
an on-card transceiver driver chip. This connector is
designed to interface without null-modem or other
changes to a DB-9 PC serial port.
Here is a summary of the connector types expected for these 7 connectors:
Connector Signal type # pins Type
J1 High power 2 Through-hole terminal block (screw connection)
J2 Low power 14 Side-facing single row shrouded header
digital & analog (1-in-line 0.100” pitch friction lock header)
J3 Low power digital 5 1-in-line 0.100” pitch header
J4 High power 3 Through-hole terminal block (screw connection)
J5 Low power 16 8 x 2 vertical header (2mm pitch)
digital & analog
J6 Low power 12 Side-facing single row shrouded header
digital & analog (1-in-line 0.100” pitch friction lock header)
J7 Low power digital 9 Side-facing D-sub 9 (Female)
2.7.1 Initial Setup
To initially set up the Developer’s Kit card for checkout and verification, four connectors must be used - J1
(Power), J2 (motor feedback), J4 (motor), and J7 (serial port). In addition, the host connector (J6) is frequently
used during testing after initial setup, in which case the serial port becomes optional. The signal connections for
these connectors are indicated in the following sections. For a complete description of all connectors see
section 5,
