is high. Next, the display must be addressed using a one byte hexadecimal value, the default to write to the
unit is 0x50, while read is 0x51. Then information can be sent
to the unit; even when reading, a command
must ?rst be sent to let the unit know what type of information
it is required to return. After each bit is sent,
the display will issue an ACK or NACK as described above. Finally, when communication is complete, the
transaction is ended by toggling the data line from low to high while the clock line is high. An example of
the use of this algorithm to write a simple “HELLO” message ca
n be seen in 3.

4.1.3 Serial Communication
In addition to being able to communicate via I2C the GLK12232-25-SM communicates natively through
the RS-232 protocol at at a default baud rate of 19,200 bps and
is capable of standard baud rates from 9600
to 115,200 bps. Furthermore the GLK12232-25-SM is also capable of reproducing any non-standard baud
rate in between using values entered into our baud rate generation algorithm and set through command 164
(0xA4). The display module communicates at standard voltage levels of -30V to +30V or at TTL levels of 0
to +5V by setting the
Protocol Select Jumpers
to TTL.
