1. General Incoming Data

Byte 1 | Byte 2 | Byte 3 | Byte 4 | Byte 5 | Byte 6 | Byte 7 | Bytes 8-32
Constant | Keys 0-4 | Keys 16-20 | Keys 32-36 | Keys 48-52 | Unit ID (0-255) | Program Switch Position | Reserved
2 | D1 | D2 | D3 | D4 | <data> | Swpos | value

D1: for all bits 0 for key up, 1 for key down. Bit 1=Key 0, Bit 2=Key 1, Bit 3=Key 2, Bit 4=Key 3, Bit 5=Key 4, Bits 6-8=0 always.
D2: for all bits 0 for key up, 1 for key down. Bit 1=Key 16, Bit 2=Key 17, Bit 3=Key 18, Bit 4=Key 19, Bit 5=Key 20, Bits 6-8=0 always.
D3: for all bits 0 for key up, 1 for key down. Bit 1=Key 32, Bit 2=Key 33, Bit 3=Key 34, Bit 4=Key 35, Bit 5=Key 36, Bits 6-8=0 always.
D4: for all bits 0 for key up, 1 for key down. Bit 1=Key 48, Bit 2=Key 49, Bit 3=Key 50, Bit 4=Key 51, Bit 5=Key 52, Bits 6-8=0 always.
Swpos: Bits 1-3=0, bit 4=0 if program switch is down, 1 if program switch is up, Bit 5=1, Bits 6-8=0.

X-keys Desktop Output Report

The following types of output reports are available; Set LEDs, Set Unit ID, Set Key and Check Key. The Unit ID is a value between 0 and 255 which can be set and read. This number stays permanently in the device independent of computer. It is useful if more than one device of the same PID will be connected to the same computer in order to distinguish the devices uniquely. The Set Key and Check Key reports are for the dongle feature, non PC users please contact P. I. Engineering for further details.

1. Set LEDs

Byte 1 | Byte 2 | Byte 3 | Byte 4 | Byte 5 | Byte 6 | Byte 7 | Byte 8
Constant | LED Command | Constant | Constant | Constant | Constant | Constant | LED Control
2 | 186 | 0 | 0 | 0 | 0 | 0 | LED

LED: Bits 1-6=0, Bit 7=1 to turn on Green LED or 0 to turn off Green LED, Bit 8=1 to turn on Red LED or 0 to turn off Red LED.

2. Set Unit ID*

Byte 1 | Byte 2 | Byte 3 | Byte 4 | Byte 5 | Byte 6 | Byte 7 | Byte 8
Constant | Unit ID Command | Unit ID (0-255) | Constant | Constant | Constant | Constant | Constant
2 | 189 | value | 0 | 0 | 0 | 0 | 0

*Make sure the programming switch is set before sending the WriteData() command in order to permanently write the unit ID to the eeprom.
