## GAMMA62T LoRa Telemetry Module 

## Transmit Mode 

## GAMMA62 module configured as a transmitter 

When configured as a transmitter the GAMMA62 module will automatically default to low power sleep mode. A change on any input(s) will cause the GAMMA62 to wake, read all inputs and initiate RF transmission, (multiple input changes may take place simultaneously). Maximum switching frequency is dependent on the LORA[TM][mode in which the GAMMA62 is ] operating see Configuring a GAMMA62 module for more information on LORA[TM] modes. 

“No Volt” Digital inputs: High impedance inputs, LVCMOS/LVTTL compatible, 5V tolerant. Can be connected directly to CMOS/TTL logic or switch inputs connected to 0V or VCC. 

## Transmitter application circuit example 

## Description: 

This example shows a GAMMA62 module configured as a transmitter with all 10 inputs connected. Each input to be connected to GND to activate. 

Application example: 

Example showing 1 transmitter paired to 3 receivers - I/O used is arbitrary.

## Receive Mode 

## GAMMA62 module configured as a receiver 

When configured as a receiver the GAMMA62 module will remain in listening mode. When a valid RF Transmission is received it will: 

1. Flash the onboard LED. 

2. Action output changes.  Each output will follow the status of its associated (paired) transmitter input. 

3. Send back an RF Acknowledge if requested. 

Digital outputs: 

Active high LVCMOS/LVTTL compatible outputs. Can be connected directly to CMOS/TTL logic or drive. 

## Receiver example application circuit 

## Description: 

This example shows a GAMMA62 module configured as a receiver with all 10 outputs connected. The external learn switch and LED are also not fitted in this example. 

## Application example: 

Example showing 4 transmitters paired to one single receiver - I/O used is arbitrary.

## Transceiver Mode 

## GAMMA62 module configured as a transceiver 

When configured as a transceiver the GAMMA62 assigns its I/O lines; 1-4 as outputs and 5-8 as inputs (as shown below). 

“ no volt” Digital Inputs: High impedance inputs, LVCMOS/LVTTL compatible, 5V tolerant. Can be connected directly to CMOS/TTL logic or switch inputs connected to 0V or VCC. 

Outputs are active high LVCMOS/LVTTL compatible and can be connected directly to CMOS/TTL logic or drive. A change on the input will cause the GAMMA to wake, read all inputs and initiate RF transmission.

## Application example: 

The below example shows two GAMMA62 modules paired in both directions.

## Parallel to Serial Mode 

When an I/O on a GAMMA62 module is activated the module will send data. 

All GAMMA62 modules within range and configured in Transceiver mode; will output the data via their TX pins. 

Note that if a GAMMA62 Module is paired with another module, when an RF command is received to update the digital outputs. The GAMMA62 module will also output a serial data string showing output status.

## Pairing Procedure 

A GAMMA62T that is set to Receive can “learn” another GAMMA62T that is transmitting or any other compatible  RF Transmitter,  to create a remote Control system. 

Each receiving GAMMA62 can learn and store upto 32 Transmitter pairings. 

One pairing is defined as either a one PIN learn or one Module learn. To Select Pin/Learn mode see later section. 

## PIN Learn 

## MODULE Learn 

User select an individual output Pin to pair with an individual transmitter input. 

This procedure automatically assigns all Transmitter inputs to GAMMA62 outputs as follows

When Set to MODULE Learn. A single pairing process automatically assigns all Transmitter inputs to all Receiver outputs, 1-1,2-2, 3-3 etc. 

This consumes only one of the Receivers memory storage (out of 32) and provides a quicker pairing process. 

When PIN Learn is selected, an Individual Transmitter input is be paired with any one of the GAMMA62 Module Outputs thus creating more complex Transmitter / Receiver relationships 

For example Transmitter input 1 could be paired with a Receiver output 4, and Transmitter input 2 could be paired with another Receiver output 4, etc.

## Notes 

Selects the type of RF Modulation. This can be: 

## FM 

LoRa Modes 1 to 7 (Spread Spectrum) 

FM Modulation provides the fastest operation time from Transmit activation to Receiver output. 

LoRa Modulation provides a longer Operating range (Mode 7 is the longest), this however increases the propagation time from Transmit activation to Receiver output.

When Acknowledgment Request is activated, the transmitting GAMMA62 includes an acknowledgement request within each radio transmission. 

When the successful acknowledge signal is received back by the transmitting GAMMA62 module, the LED will briefly flash, if no acknowledge is received the LED will flash rapidly 5 times. 

NOTE : This will be after the transmitter has retried four times. 

Due to hardware limitation I/O 9 & 10 cannot provide the “Acknowledgment” feature 

RF Acknowledgment from Receiver - Warning! Whilst in theory if an RF signal can be transmitted one way then it can be returned, in practice occasionally the received acknowledgement many not penetrate as well as the GAMMA62 transmitted signal.

## Receiver Serial Data Output 

GAMMA62 in RX and TRX mode automatically outputs the serial number, button and battery status of any received compatible RF transmitter. This data may be fed directly to a microcontroller or RS232 type driver circuit which may then be fed directly to a PC serial port. Serial data is output on every packet receipt regardless of whether the Transmitter has been learnt or not. The serial data packet contains a learn bit to show if an encoder input is learnt. 

Serial data configuration 

Baud Rate: 19,200 Data bits: 8 Parity: none Stop bits: 1 Handshaking : none 

Serial data format: 

Serial number [SN1 SN2 SN3]: 

Made up of three 8-bit bytes where the most significant byte is transmitted first. 

SN1 SN2 SN3 IP1-8 IP9-16 TXV STAT RSSI CR LF 

10 bytes of serial data sent Line Feed - $0A (hex) Carriage Return - $0D (hex) RSSI 0 - 255 (hex) Learn status and low battery Tx battery voltage (if available) Input status on Tx 3 byte serial number 

Example:  12ABAA (hexadecimal) or 0001 0010 1010 1011 1010 1010 (binary). 

Tx inputs [IP1-8 IP9-16]: made up of two 8-bit bytes. 

The low order byte is sent first representing inputs 8 down to 1 where the MSB is input 8 and the LSB is input 1. The high order byte is sent next representing inputs 16 down to 9 where the MSB is input 16 and the LSB is input 9. 

A bit at state 1 represents an encoder input as active. Using this method inputs can be multiplexed giving maximum versatility. Example:  00000000 00010000 Shows input 13 active. 10000000 00000000 Shows input 8 active 10000001 10000000 Shows inputs 16, 8 and 1 active 

Learn status and low battery: One 8 bit byte: Bit0 shows low battery on Tx - where 1 = Low battery Bit1 shows learn status of Tx - where 1 = Learnt

## Range Considerations 

The antenna choice and position directly affects the system range, keep it clear of any large metal parts. The best position is protruding vertically from the top of the product. This is often not desirable for practical reasons and thus a compromise may be needed. Note that the space around the antenna is as important as the antenna itself, all radio systems are dependent on a radio signal being received through   airspace. 

The range quoted is the optimal in direct line of sight, without obstacles and in good atmospheric conditions. 

Range is affected by many things, for example local environmental conditions, atmospheric conditions, interference from other radio transmitters. For evaluating the local environment please see our RF meter (DS006) 

In very worse case applications the range quoted may be reduced dramatically below the optimal range stated.
