Connection to PC
To connect a PC to the ergometer, use a 0-modem
cable (RS232) with a 9-pin D-sub female at each end.
If no RS232 serial port is available on the PC use a
USB serial adaptor to connect to an USB port.
Follow these steps to install the USB adaptor drivers:
Locate the USB adaptor. 1.
Inside the USB adaptor packaging, there is a mini-2.
CD.
Insert the mini-CD into the CD-ROM drive and 3.
install the driver software. If there is no CD drive
on your computer, driver software is available for
down from the website (http://www.vscom.de/
USB-CD).
Finalize the driver software installation by 4.
inserting the USB adaptor.
Install the Monark Software disk. 5.
Connect the USB Adapter to the Serial Cable and 6.

To control the ergometer use the PC software supplied
with the ergometer and which is common to the
models 831 E och 939 E, or other PC software made
for the Ergomedic 839 E.
From software version MEC3V11R14 and later
settings can be made from a PC in terminal mode
