Device Description
Supported treadmills and
ergometers
Supported devices connect to the MAC 1600 system via
the serial port labelled COMM A on the back of the unit.
The device can be controlled through this connection.
When a test phase changes, a signal is sent from the
system to the device to change speed, grade, or load, as
appropriate. Manual overrides of the device can also be
initiated from the MAC 1600 keyboard. See “Stress Test
Keys” on page 7-5 for more information.
Supported devices include:
T2000 and T2100
Trackmaster TMX425
Excalibur
Ergoline 900 / Variobike
eBike
Ergometers with remote
start
These devices also connect to the MAC 1600 system via
the serial port labelled COMM A on the back of the unit.
However, they are not controlled by the system. Instead,
when the device changes load, it signals the system, which
changes test stages accordingly.
Unsupported treadmills and
ergometers
Unsupported devices do not connect to the MAC 1600
system. Instead of signaling the device when a test phase
changes, the system notifies the operator, who manually
adjusts the device parameters.
Master Step This device does not connect to the MAC 1600 unit. The
system emits a tone to instruct the patient when to take a
step.
