Evertz does not recommend altering the jumper settings for port A, as it may
make in-field reprogramming very difficult for the user.
IMPORTANT INSTALLATION NOTICE: For a reliable telephone connection to
the modem in this caption encoder, a direct telephone line must be used.

Serial Port / Modem Connections

PORT A: A 9-pin male 'D' connector for connection to a computer with
captioning or XDS control software.
Engineering menus are used to set the correct baud rate, word
size and parity for use with your captioning software.
section 3.3) This port is also used to update the firmware in the
Closed Caption Encoder. (See section 5.4)
As configured from the factory, the pinout of this connector is
designed so that you can use a readily-available "null modem"
cable to connect to your computer via RS-232 port. Jumper
settings inside the unit may alter this pinout, and reconfigure for
RS-422 communications. Please refer to Figure 2-8 and Figure
2-9 for typical port pinouts and connections to a computer.
PORT B, C: These 9 pin male 'D' connectors may be used for connection
to computers with captioning or XDS control software. The front
panel Engineering menus are used to set the correct baud rate,
word size and parity for use with your captioning software. (See
section 3.3)

typical port pinouts and connections to a computer.
MODEM D, E: These RJ11 jacks are used to connect the internal modems
to the telephone line, so that computers at other locations that
are running captioning or XDS control software can connect to
the 8084(AD). Use of the MODEM E port requires the 8084-
MDM2 option to be installed in your unit. If the option is not
installed, this RJ11 jack will not be connected internally. The
front panel Engineering menus are used to set the correct baud
rate, word size and parity for use with your captioning software.
