Definitions
ASCII: American standard code for information interchange used to give standardized numeric codes
to alphanumeric characters.
BPS:
DOW: Dallas One-Wire protocol, similar to I
wire carries data, while two others supply power and ground. Matrix Orbital tests non-parasitic devices
only, those that do not draw power from the data line; however, some parasitic devices may work.
FFSTN: Double film super-twisted nematic in reference to an LCD. The addition of two layers of film
between the STN display and polarizer improves contrast.
GPO:
GUI:
Hexadecimal: A base 16 number system utilizing symbols 0 through F to represent the values 0-15.
I
slow speeds from a master to up to 128 addressable slave devices. A display is a slave device.
LSB:
MSB:
RS232: Recommended standard 232, a common serial protocol. A low level is -30V, a high is +30V.
RS422: Recommended standard 422, a more robust differential pair serial protocol.
SDA:
through a resistor. Nominal values are between 1K and 10K Ω.
SCL:
high through a resistor. Nominal values are between 1K and 10K Ω.
STN:
themselves in the same direction and pass light. In an excited state these crystals align to block light.
Super-twisted crystals move from 180 to 270 degrees between to increase contrast over TN models.

Bits per second, a measure of transmission speed.
General purpose output, used to control peripheral devices from a display.
Graphical user interface.
Inter-integrated circuit protocol uses clock and data lines to communicate short distances at
Least significant bit or byte in a transmission, the rightmost when read.
Most significant bit or byte in a transmission, the leftmost when read.
