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 XDS encoder.
6.1.5 I see "BUFFER OVERFLOW" or "PARITY BAD" messages on
the front panel.
Please refer to the previous question, 6.1.4 "What baud rate and port
settings should I use?"
6.1.6

How do I check the logic levels and pinouts of the serial ports?

The logic levels (RS-232 or RS-422) can be checked from the front panel
without removing the XDS encoder from service. Instructions are provided
under 5.5.3 "Viewing Firmware and PLD Revision Levels". Since ports B
and C only have two possible pinouts (with 8058 submodule), the logic
level setting and pinout are generally synonymous. The only way to verify
the pinout of port A is to remove the top cover and examine the locations of
the jumpers in jumper block J9.
6.1.7

How do I check the status of my power supplies?

Power supply status can only be monitored on XDS encoders with an 8058
submodule and dual power supplies. Refer to 5.5.3 "Viewing Firmware and
PLD Revision Levels"
6.1.8

Captions are not being encoded at all.

The 8083XDS-AD only encodes XDS and Text Article information. The
8083XDS-AD does not encode Closed Captioning. Please refer to the
Evertz Closed Caption Encoder line to find a product suitable for your
application.
