Models 8084/8084AD/8085 Closed Caption Encoder Manual
CMD FMT ERROR will also be displayed if the 8084(AD) receives a request
to delete an article that has not been defined. It will respond by
sending back an error code 'E4' to the control port.
OUT OF MEMORY If the 8084(AD) has no more article/XDS memory
available it will display this message on the front panel and
respond by sending back an error code 'E6'.
PARITY ERROR If there is a problem with the serial communications baud
rate, parity or word size the 8084(AD) will show this message on
the front panel.
ACCESS ERROR If one of the control ports tries control a data stream,
which is already being controlled by another port, or if the
control port has not been given access privilege to the data
stream, the 8084(AD) will respond by sending back an error
code 'E9'.
4.2.6 Command Differences Between Operating Modes (Legacy
Operation)
The 8084(AD) operates in one of two basic operating modes - Stream
mode or Field mode. Use the MODE menu item on the Engineering Menu
to select which operating mode is to be used.
When Stream mode is selected the 8084(AD) manipulates each data
stream independently of each other.
individual caption data streams can be passed through, removed, or
replaced with new data by the caption encoder. New caption data may
also be inserted into existing data streams. The commands available in
Stream mode are discussed in section 4.4.
When Field mode is selected the 8084(AD) manipulates caption data on a
field-wise basis. In Field mode, all the caption data in an entire field will be
passed, removed, or replaced with new data.
Some of the commands are common to both operating modes. These
commands are discussed in section 4.3.

Set Baud Rate

The caption encoder's serial remote control ports may be set to operate at
any standard baud rate from 1200 to 38400.
executed the new baud rate will become immediately active, and the
sending computer must immediately switch to the new rate. The new baud
rate is stored in non-volatile memory and will be restored when the unit is
powered up. The baud rate can also be set using the Engineering menu
BAUD RATE item. (See section 3.3.1)
