XIII. CryoTel® Serial Communications Command Reference
Control the CryoTel® GT with any terminal emulator program. A common choice is Hyperterminal, as it
is included with Windows, (Windows 7 users may need to download Hyperterminal). The connecting
cable for basic functionality is included.
Caution: Use of an external program, such as LabVIEW™, to establish closed loop control of the
cryocooler via serial communication, may cause controller malfunction. Manual set point adjustments
may be made as required without problem.
