Command Summary
9 Definitions
ASCII: American standard code for information interchange used to give standardized numeric codes
to alphanumeric characters.
BPS:
Bits per second, a measure of transmission speed.
Byte: An unsigned data packet that is eight bits long.
DOW: Dallas One-Wire protocol, similar to I
2
C, provides reduced data rates at a greater distance. One
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.
GPO: General purpose output, used to control peripheral devices from a display.
GUI:
Graphical user interface.
Hexadecimal: A base 16 number system utilizing symbols 0 through F to represent the values 0-15.
I
2
C:
Inter-integrated circuit protocol uses clock and data lines to communicate short distances at
slow speeds from a master to up to 128 addressable slave devices. A display is a slave device.
Integer: An unsigned data packet that is thirty-two bits long, in little Endian format.
LSB:
Least significant bit or byte in a transmission, the rightmost when read.
MSB: Most significant bit or byte in a transmission, the leftmost when read.
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:
Serial data line used to transfer data in I
2
C protocol. This open drain line should be pulled high
through a resistor. Nominal values are between 1K and 10K Ω.
SCL:
Serial clock line used to designate data bits in I
2
C protocol. This open drain line should be pulled
high through a resistor. Nominal values are between 1K and 10K Ω.
Short: An unsigned data packet that is sixteen bits long, in little Endian format.
TTL:
Transistor-transistor logic applied to serial protocol. Low level is 0V while high logic is 5V.
