What Baud Rate and Port Settings Should I Use?

While the unit is capable of running at 57.6k baud on all internal serial ports, it is not necessary to run at
the fastest baud rate possible for most captioning operations. NTSC captions are encoded at a maximum
of 60 characters per second in each field. A serial port set to 1200 baud can transfer data at up to 120
characters per second including 7-bits of data, start, stop and parity bits. This is adequate for most
captioning applications since the communications overhead is generally very low.
Some older PC's do not function correctly at over 19.2k baud, especially when running under Windows.
Many PC's also have difficulties at 19.2k baud and above when using only the software (XON/XOFF) flow
control method. Try turning on hardware (CTS/RTS) flow control on your computer if the captioning software
supports it, and/or reducing your communications baud rate. Make sure that you alter your captioning
computer's serial port settings to match those of the caption encoder.

Captions are Not Being Encoded At All

If there is no option in the captioning/teleprompter software for the Evertz encoder, configure your software
to communicate with an EEG 270, EEG 370 or EEG 470 model Smart Encoder. The Evertz caption protocol
is compatible with these units.
Make sure that the caption encoder unit is set to the correct video type, 525-60 for component SD-SDI.
Check that the caption keyer is turned on.
Check your serial port communications settings. Make sure that these are identical between the caption
encoder and the attached captioning computer.
Check that the unit is receiving data from the serial port or modem.
Try enabling the built-in CEA-608 test message. If you still cannot see captions, then it is likely that
downstream equipment is corrupting the caption data, or your caption decoder is not functioning correctly.

Captions are Not Being Encoded Correctly

If there is no option in the captioning/teleprompter software for the Evertz encoder, configure your software
to communicate with an EEG 270, EEG 370 or EEG 470 model Smart Encoder. The Evertz caption protocol
is compatible with these units.
Make sure that the caption encoder unit is set to the correct video type, 525-60 for component NTSC.
Check your serial port communications settings. Make sure that these are identical between the caption
encoder and the attached captioning computer.
Check that the unit is receiving data from the serial port or modem.
If certain accented and special characters do not display correctly, this is likely the fault of the caption
decoder being used to display the captions. Some decoders do not support the entire character set for
captions.
Certain teleprompter software packages have been known to not encode accented characters correctly.
Please contact your software provider for possible updates before contacting Evertz technical support.
