If a Manual Control Pendant is not connected to the secondary RS-232 port provided in this
connector, this serial interface can be accessed via a GPL procedure as device "/dev/com2" for
general communications purposes.
NOTE: Unlike the primary serial interface, this secondary serial interface does not
support flow control.The RS-485 port is used internally to communicate with the
gripper controller and is also be used for the Remote IO option. As such it has a
dedicated protocol and is not available for general use. See Table 5-2 for more
information.

Digital Input Signals
The standard PreciseFlex

400 robot provides one general-purpose optically isolated digital input
signal at the Facilities Panel (in addition to those signals that are available at the Gripper Control
Board). This line is accessed in the Phoenix 5-pin E-Stop connector and is connected to Digital
Input 3 in the controller. See Figure 5-22.
