Placing the telefax (option)
A digital telefax (Group 4) can be con-
nected to one of the ISDN outlets, or to
an ISDN bus for transfer at 64 kbps rate.
An analogue telefax (Group 3) should
be connected to the FAX (GR3) outlet,
providing up to 28.8 kbps transfer
speed.
Placing the PC (option)
A PC w/ISDN card can be con-
nected to one of the ISDN outlets,
or to an ISDN bus for 64 kbps rate
data communication for installation
up to 100 m away from the MCU.
With the PC connected to the USB/
RS-232/RS-422 port it can also be
used for control and configuration
of the Main Communication Unit.
This requires that the vtLite Marine
program accessible on the Nera F77 CD is installed.
Connection to the USB/RS-232/RS-422 port also allows
64 kbps data transmission.
