Sync – Two byte Sync word used to align data. Value is always 0xD391. Length – Packet Length in bytes, equal to the length of the Payload + 1. Node – Node Address. Composite Master/Slave ID. The Master ID is in the upper 4 bits and the Slave ID is in the lower 4 bits. For Discovery Mode, this byte is set to 00. Payload – The payload, 1 to 8 bytes. CRC – 16 bit CRC starting with the Length byte and ending with the last payload byte. UART Data Packet Protocol (Master Only) Any data sent to the adapter via the UART Rx line must adhere to the following protocol: 1 Byte 1 Byte 1 to 8 Bytes, variable Packet Length Slave ID Payload Length – Total length of the packet in bytes (Payload + 1). The upper 4 bits always contain the value 0xA0, and the lower 4 bits contain the byte length. Valid byte lengths are 0x01 through 0x08. SlaveID – Destination of packet. The upper 3 bits always contain the value 0xA0, and the lower 5 bits define the Slave ID. Valid values are 1 through 31. Payload – The payload, 1 to 8 bytes. UART Data Packet Protocol (Slave Only) Data that is sent out of the adapter via the UART Tx line is formatted as follows: 1 Byte 1 to 8 Bytes, variable Payload Length Payload Payload Length – Total length of the payload in bytes. Valid values are 1 though 8. Payload – The payload data. RF ACK Packet Protocol ( Sent by Masters, Received and Sent by Slaves) 1 Byte 1 Byte 1 Byte 1 Byte Packet Length Composite ID ACK Command Master’s ID Packet Length – Packet Length, always set to 0x03. Composite ID – The upper 4 bits contain the Master’s ID, and the lower 4 bits contain the Slave’s ID. ACK Command – Always the value 0xA9. Master’s ID - Master ID in lower 4 bits.

Discovery ID – Composite Discovery ID, set to 0x00 in current versions. Discovery Cmd – Discovery Command, always set to 0xAF. New Master ID – The new ID of the Master that the Slave must use. New Slave ID – The new ID that the Slave must use as its node address. New Channel – The new channel frequency that the Slave must use for all future reception (1 - 29). End User Programming In order for two or more adapters to communicate, one adapter must be set up as a Master and all others (1 through 31) must be configured as slaves. After a reset, all modules are locked in a special mode, waiting for Master/Slave programming. This mode is indicated by either Red or Green LEDs on, but not both. Pushing and releasing the button will toggle between Red and Green. STEP 1: Factory Reset Procedure 1) While Holding down the button, apply power to the adapter. 2) Continue to hold down the button for approximately 5 seconds, or until the both LEDs illuminate. 2) Release the button. The Red LED will be on and the Green LED goes off. STEP 2: Master/Slave Setup Procedure 1) Pressing and releasing the button will toggle the LEDs. To setup an adapter as a Master, press and release the button until the Green LED is on. To setup as a slave, press and release the button until the Red LED is on. 2) While the desired LED is on (Red=Slave, Master=Green), press and hold down the button for at least 5 seconds. 3) When both LEDs turn off, release the button. Both LEDs should now be on. STEP 3: Discovery Mode Procedure Discovery Mode links a single Master to one or more Slaves. Discovery Mode mjst be run immediately after the Master/Salve Setup Procedure is complete. To run Discovery Mode: 1) Press and release the button on the Master wireless adapter. Both the Red and Green LEDs will flash. 2) Within 30 seconds, press and release the button on the LEFTMOST Slave adapter. Both the Red and Green LEDs will flash. 3) After a few seconds, the Red LED will turn off and the Green LED will turn on at both adapters. To configure multiple slaves, it is important that the slaves be set up in sequence. The LEFT MOST RF module should be the FIRST Slave selected. To program additional slaves, press the button on the Master again, followed by the button on the next Slave, going from left to right until all slaves are programmed.
