CDS on the DA-15 Connector
CDS on the DA-15 Connector
A special version of the D-styleSmartMotor with the CDS CAN connector option allows CAN bus
network wiring through the DA-15 connector (15-pin D-sub I/O connector shown in the following
figure). This is an advantage when the M-style CAN connector is not desired. The D-style motor with
the CDS CAN connection option can be used as the terminating node. To enable this, a 120 ohm
terminating resistor (shunt) must be placed across pins 10 and 11. For details, see the following
figure.
NOTE:
Terminating resistors (shunts) must always be used at both ends of a CAN bus network.
Motor as Terminating Node
NOTES: A terminating resistor (shunt) is required at each end of the bus.
Bus must be multi-drop as shown,
not
a star network.
24V CAN bus power connection is
not
required at the motor.

Schematic for CDS Option, D-Style SmartMotor Used as Terminating Node
CDS on the 7W2 Connector (CDS7)
Alternatively, the CDS7 option on the D-style SmartMotor now allows CDS to be wired through pins 1
and 2 of the 7-pin D-Sub (7W2) connector as shown in the following figure. The wiring is accomplished
through the use of a single Add-A-Motor cable (PN: CBLSMCDS) that carries Power, RS-232, and CAN
bus to the next motor in the chain. This method allows pins 10 and 11 on the 15-pin D-sub connector
to be used as an easy terminating point on the last motor by simply placing a 120 Ohm terminating
resistor (shunt) across those pins OR
installing the Pass-Thru Terminator (PN:
CBLSM-TR120) on that
connector.
This design not only greatly simplifies motor installation, but also does the same for CAN bus
addressing. With CDS7, the SmartMotor is the first and only single-cable, point-to-point integrated
motor to have both motor-to-motor full communications and control capability, and only single-cable,
point-to-point for both power and communications in general.
