running or paused. Data will be lost as soon as the schedule is terminated.
k. Auxiliary Outputs #3 and #4 are available.
Escape (ESC)
Escape set up is similar to Avoidance with a single interval control timer to limit the duration of the negative
reinforcement when an animal fails to respond. Use the Additional Settings Menu to present a light or tone
stimulus concurrent with shock.
a. One or more acceptable response(s) may be selected to escape a negative stimulus of shock or air puff
stimulation.
b. Interval Control 1 determines the UCS interval. It may be set from 0.1 to 99.9 seconds in 0.1 second
increments
c. Counters are provided for all responses. Selected/Acceptable responses can only increment once in any
given trial and may be added together to obtain total escapes.
d. Counters are provided for presentations of shock and air puff stimulation as well as activations of the
shaping push button.
e. A trial count and escape counter are provided.
f. A response latency timer is provided with a resolution of 100 ms.. This timer resets at the beginning of
each trial so data must be recorded manually.
g. The shaping push button is used to start each trial. The red status light signals the UCS interval. The
shaping push button may also be used while the UCS timer is running to terminate a trial.
h. Outputs are turned OFF (except Auxiliary #3 & #4 if selected) and counters frozen between trials.
i. A single Reset pauses the schedule and turns selected outputs OFF. The green status light flashes while
the schedule is paused. Press Run to continue and Reset to terminate the schedule. Use the Down button
to reveal multiple data screens and the Up button to return to previous screens while the schedule is
running or paused. Data will be lost as soon as the schedule is terminated.
j. Auxiliary Outputs #3 and #4 are available.
Auxiliary Output Control
The Auxiliary outputs Aux. 1-4, located on the back panel, are controlled by four PhotoMOS solid state relays
used as switch closures for external devices. The 28 V DC power supply used with the 81335C control may
be accessed at the rear panel terminal strip and used to power auxiliary devices up to a maximum combined
load of 1 Amp.

Aux. 1 is wired in parallel with the Left Front Stimulus Light. The FR LF STIM LITE must be fully activated (Level
20) to use Auxiliary 1 to control an alternative stimulus.
Aux. 2 is wired in parallel with the Pellet Reinforcement output. The reward pulse time must be appropriate
to the alternative device connected to this relay.
Aux. 3 is turned on for approximately 50 ms with each “Acceptable Response” selected by the user. This output
was intended for the Step function on old mechanical cumulative recorders, but could be used for other
purposes as well.
Aux. 4 when selected is turned on for the duration of a schedule. This is appropriate for house lights, cubicle
fans, or other devices that need to run continuously while a schedule is active.
