4. COMMUNICATIONS PROTOCOL

The Control System (CS) will initiate ALL communications with the ST100 except as noted
below. The ST100 will respond to CS commands within 20 milliseconds after complete receipt of
a command.

The ST100 will transmit data to the CS, without CS initiation, under the following three (3)
conditions:

a) Upon completion of Power Up of the ST100, it will transmit ASCII "P" + 00H. No

response from the CS is expected.

b) Upon detection of a key press or key release, the ST100 will transmit the current state of

the key switches - ASCII "S" + Data Byte. No response from the CS is expected. See
Switch Data Byte Chart below.

c) Upon detection of Shuttle Wheel motion, the ST100 will transmit ASCII "W" + ASCII

"Z" for clockwise motion, or ASCII "W" + ASCII "z" for counter-clockwise motion. No
response from the CS is expected.

5. COMMANDS

These commands are transmitted by the CS to the ST100. The ST100 will respond with ACK (40H), NAK
(80H) or the appropriate Status information.

LED ON/OFF: ASCII "L" + MSB LED Data Byte + LSB LED Byte
(See LED Data Byte Chart)

The ST100 will respond with ACK (40H) or NAK (80H). The LED Data Bytes
will determine the ON/OFF state of each LED.

KEYBOARD QUERY: ASCII "K"

The ST100 will respond with NAK (80H) or ASCII "K" + Switch Data Byte.
The Switch Data Byte represents the current status of the keypad. See Switch
Data Byte Chart below.

MESSAGE DISPLAY: ASCII "D" + ROW + 16 Character Message
ROW: "1" = top row of the display
"2" = bottom row of the display

16-Character Message will consist of 16 printable ASCII characters. The
message MUST contain 16 characters.

The ST100 will respond with ACK (40H) or NAK (80H).

SWITCH DATA BYTE: Pressed = 1 Not Pressed (Released)=0
Bit7= Switch #7 (Shift Key)
Bit6= Always 0
Bit5= Switch #6
Bit4= Switch #5
Bit3= Switch #4
Bit2= Switch #3
Bit1= Switch #2
Bit0= Switch #1

LED DATA BYTE: LED ON= 1 LED OFF= 0

Bit7= Don't Care
Bit6= Don't Care
Bit5= LED #6
Bit4= LED #5
Bit3= LED #4
Bit2= LED #3
Bit1= LED #2
Bit0= LED #1
