Once the sequence has been completed, the screen will revert to the number of cycles programmed originally. To begin
another cycle test, press UP or DOWN.
Travel indication and limit switch operation is the same as in Basic Mode.
6.5 PC Mode
The test stand may be controlled by a computer through the Series DC controller via serial communication. A list of
supported ASCII commands is provided below. All commands must be lowercase.
Note: Functions relating to distance measurement (indicated with an asterisk) are applicable only with the TSTM /
TSTMH stands.
a Request speed
b Set travel units to inches or revolutions
c Enter cycle mode
d Move down or CCW
e Set speed (ex. e10.00 = 10.00 in/min)
f Set cycles (ex. f0500 = 500 cycles)
g* Set lower travel limit (ex. g90.0 = 90 degrees)
h* Set upper travel limit (ex. h180.0 = 180 degrees)
i Set travel units to millimeters or degrees
j Set speed to maximum speed
k Set speed to minimum speed
l* Enter travel limit mode
m Enter manual mode
n* Transmit travel and torque readings
o Set speed to programmed speed
p** Request stand status**
q Request number of cycles completed
r Request number of cycles set
s Stop
t Reset cycle counter to zero
u Move up or CW
v* Request upper travel limit
w* Request lower travel limit
x* Request travel value
z* Reset travel to zero
*Applicable only to the TSTM / TSTMH test stands.
** The transmission of ASCII “p” will return the stand status.
The following are the return codes and their definitions.
Test stand status U = Moving up or CW
D = Moving down or CCW
S = Stopped
Operating mode C = cycle mode
L = limit mode
M = manual mode
Limit switch status UL = crosshead at upper limit
DL = crosshead at lower limit
Commands relating to Mark-10 force and torque gauges are NOT the same as indicated in the respective user’s guides.
A list of supported ASCII commands is provided below. All commands must be uppercase:
A Displays current unit
F Toggles between Normal and Data Collect modes
P Steps through Normal mode, Tension/CCW Peak mode, and Compression/CW Peak mode
R Zeroes the gauge (zeroes all modes)
S Sends currently selected mode (Normal, Tension/CCW Peak, Compression/CW Peak, or Data Collect)
U Steps through units
X or ? Sends currently displayed reading
Y Enables RS-232 output and sends continuous data stream when in Data Collect mode
Z Zeroes the currently selected mode
