(9) Teaching connector  
  The teaching interface connects IAI’s teaching pendant or a PC (PC 
software) to enable operation and setting of your equipment from the 
teaching pendant/PC. The physical interface consists of a RS232C 
system based on a 25-pin, D-sub connector. The signal level conforms to 
RS232C, and a desired baud rate (up to 115.2 kbps) can be selected 
depending on the program. RS232C communication is possible only when 
the mode switch (12) is set to the MANU position. 
You can also use an ANSI teaching pendant equipped with an ANSI-
compliant double-action enable switch. Whether the controller supports an 
ANSI teaching pendant or IAI’s standard teaching pendant can be set 
using the selector switch (8) provided above the teaching connector. (P 
type only) 
*  With a Q-type controller, connect the supplied dummy plug to the 
teaching connector in the AUTO mode.

Connection 
cable 
 Dedicated cable 
Power supply  5 VDC or 24 VDC  A multi-fuse (MF-R090) is installed to 
protect each line against short current (the 
fuse will trip with currents of between 1.1 
A and 2.2 A). 
Protocol X-SEL teaching 
protocol 
The connector supports the X-SEL-J/K 
teaching pendant interface protocol. 
Emergency-stop 
control 
Series emergency-
stop relay drive (24 
V) 
An emergency-stop relay drive line is 
provided in the interface connector. This 
line is connected in series with other 
emergency-stop contact. 
Two independent emergency-stop input 
circuits are provided as a redundant safety 
design. 
Enabling control Enable switch line 
(24 V) 
A line for connecting an enable switch is 
provided as an operator interlock. Two 
independent enable input circuits are 
provided as a redundant safety design. 
(12) Mode 
switch 
AUTO/MANU switch Whether or not the teaching pendant can 
be used is set by the AUTO/MANU mode 
switch. 
The controller establishes a handshake 
with the teaching pendant only when this 
switch is set to the MANU mode. Note, 
however, that the teaching pendant 
displays the monitor screen regardless of 
the AUTO/MANU setting.
