CHAPTER 2 CONNECTION
2.1.4 Connection of external sense clips
The EP-784915GF-R is provided with 8 external sense clips that can trace signals of hardware on the target system
in real-time.
Since the external sense clips are directly connected to the HCT244 input buffer in the IE-784000-R, they are TTL-
level inputs.
Normally, there are 8 external sense clip input signal lines, but the signal line of external sense clip 1 can be used
as an outgoing trigger output signal line when an event occurs by setting the OUT command of the IE-784000-R (see
the IE-784000-R User’s Manual for details).
Cautions 1. Connect the external sense clips only to the TTL-level signal lines. If connected to signal lines
other than the TTL-level signal lines, they cannot detect high/low levels accurately, or the
sensor in the IE-784000-R may be destroyed depending on the voltage level.
2. When external sense clip 1 is used as an external trigger output, ensure that external sense
clip 1 is not connected with the signal output line. Erroneous connection may cause
malfunction.
