NOTE: The XMCP and XFP connectors on the controller can be interchanged without electrical
damage. However, neither the Front Panel nor the pendant will work properly unless they are
plugged into the correct connector.
Remote Pendant Usage
Customers can build an extension cable to place the pendant in a remote location. The exten-
sion cable must conform to the following specifications:
Wire Size: must be larger than 26 AWG.
l
Connectors: must be 15-pin, standard D-sub male and female.
l
Maximum cable length is 10 meters.

3.6 Connecting User-Supplied Digital I/O Equipment
The controller contains two options for connecting Inputs and Outputs (I/O). I/O can be hard-
wired to the XDIO and/or Controller Area Network (CAN) connectors.
DeviceNet Connector
The DeviceNet connector on the controller is used to interface to a CAN using the DeviceNet
protocol. See Adept DeviceNet on page 85 for details.
XDIO Connector
The XDIO connector on the Adept SmartController EX motion controller is a 50-pin, standard
density D-Sub female connector (see SmartController EX Connectors and Indicators on page 27
for location). There are 12 inputs and 8 outputs, each optically isolated from the circuitry of the
controller. The signals are numbered 1001 through 1012 for the inputs and 1 through 8 for the
outputs. All the signals have independent source and ground connections. These inputs con-
tain the four high-speed inputs that are used by the system for interrupts and latching. The out-
puts, although independent, have a lower current rating of 100 mA compared to 700 mA for
the extended outputs on the sDIO module (described in sDIO Module on page 61). See the eV+
Language User's Guide for information on digital I/O programming.
The connector also provides 24 V pins for powering customer equipment. There are four 24 V
pins and four ground pins, which are limited to a total of 1 A of current. The source of the 24
V is the XDC connector on the front of the controller.
Input Signals
The XDIO connector handles input signals 1001 to 1012. Each channel has an input and a cor-
responding return line. See the following table for input specifications. The connector pin-outs
are shown in the table XDIO Digital I/O Connector Pin Assignments on page 48.

CAUTION: Do not modify the cable that is attached to the pendant. This
could cause unpredictable behavior from the robot system.
