8.1.8 General Purpose Output On (254 86 [gpo #])
note that ON means that the output is pulled low.
8.1.9 General Purpose Output Off (254 87 [gpo #])
OFF allows the output to "float". For G2 OFF pulls the output to +5V.

The change in address is immediate. This address is 0x50 by default, and is reset temporarily back to that
value when the ’manual over-ride’ jumper is used on power up.

a 1-byte hex value. Values for various modules at the time of this publication are as follows;
8.1.12 Set RS-232 Port Speed (254 57 [speed])
ately. [speed] is a single byte specifying the desired port speed. Valid speeds are shown in the table below.
The display can be manually reset to 19,200 baud in the event of an error during transmission (including
transmitting a value not listed below) by setting the ’manual over-ride’ jumper on the display controller
board during power up. This command is ignored until this jumper is removed again.
