HARC40 WITH USB Connection
As a result of ISA Board connections being phased out of
Computer design, an
external Interface with a USB
connection, has been developed for H-Link connection to
the CS-NET. This also makes the application more flexible
in that it can be connected to a portable computer enabling
a service engineer to monitor systems which are not
connected to a CS-NET software.
The Installation must be carried out as detailed below.
?
NOTE:
All cables must be shielded and at least 0,75 mm²
cross section. Maximum length is 1000 m.

USB connection cable.
Switch the computer on. Windows will automatically detect
that the Interface is connected and that the device
“HARCUSB” is available at the CD/CDROM. Windows will
automatically terminate the installation of the device.
Connect the CS-NET cable on the Interface to the H-Link
connection on any one of the indoor or Outdoor Units.
