The laser extensometer must be configured in order for the remote laser disable
function to operate; contact MTS for configuration information. A 5 V level must
be applied across pins 5 and 3 to turn the laser on. Removing the applied 5 V
level turns the laser off.

The serial input/output connects to the modular jack labeled Serial I/O Port
located on the controls side of the instrument. The Serial I/O Port modular jack
uses only 4 pins:

An accessory cable assembly (7.6 m [25 ft.], MTS part number

connection to the serial port of an IBM compatible PC; contact MTS for
additional information.
