Monark 831 E
11
Printer
The 831 E Ergometer interfaces to several optional
devices. A parallel interfaced printer may be attached
to provide written reports.
The terminal or the computer attaches both via a serial
cable to the 9-pin interface connector located on the
front of the ergometer. Attach a printer if available to
the parallel port on the front.
If the instrument is a terminal or printer, the system
may need to be set-up. Verify that the System set-up
have been set to enable automatic printout. If it has
been disabled, no output will reach the device until
it has been enabled. Also, the baud rate selected by
the interface cable must match that of the device. If
the device is a printer, proper paper loading and unit
selection must be completed prior to operation (refer
to printer instruction manual).
The automatic printout length is a preset to eleven
inch pages for standard fanfold or zee-fold paper. At
the top of the each page, a header designating the
columns is printed.
The time period between the printing of each line
may be set as desired, from 0 (continuous output) to
255 seconds in one second increments. The standard
setting is 15 seconds between printouts. This provides
reasonable documentation while not wasting large
quantities of paper.
Analogue control
The work load of the Ergometer can be controlled
by external devices such as an analogue ECG device
(must be between 2 and 4 volts to operate properly).
For settings, see the manual for the terminal and
manual for the software.
