4.1.3 Serial Communication
In addition to being able to communicate via I 2 C the communicates natively through the RS-232 proto-
col 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 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 com-
municates at standard voltage levels of -30V to +30V or at TTL levels of 0 to +5V by setting the Protocol
Select Jumpers to TTL.
