## Applications 

ZETAPLUS20 makes a radio data link easy. It has a simple interface using either SPI or UART (LV RS232) and provides a plug ‘n’ play RF comms to any application. 

With connection to power, comms and antenna, the user can start sending and receiving data immediately. No other external components are required. 

With a highly tuned on-board RF matching network ZETAPLUS20 outperforms other modules achieving range far in excess of its competitors for the given power output/power consumption. Specifications are stated from the module I/O (not the pin of the IC on the module).

## Using ZETAPLUS20 

Using ZETAPLUS20 is easy, communication can be  via SPI interface or UART (LVTTL). The module will automatically communicate to its host in the same way that it was addressed, i.e. if ZETAPLUS20 receives communications on its SPI interface, then it will reply on the SPI. If comms was last received on the UART interface then it will reply on the UART interface. 

Using SPI ,  to Transmit data  simply load the correct decimal byte values into the SPI TX register. When ZETAPLUS20 receives RF data from another ZETAPLUS20 module it will output this using SPI, the nIRQ line will be pulled low, this shows that data will be ready to be read from the SPI register to the host. 

Using UART (LVTTL) to Transmit load the correct decimal byte values into the UART TX register, When ZETAPLUS20 receives RF data from another ZETAPLUS module it will output the data via the UART-TX output pin of the module to the host.

## UART Configuration 

## UART Configuration: 

Baud rate: 19200, Data bits: 8, Parity: none, Stop bits: 1. 

Note: all UART I/O are at Low level and must not exceed 5V. If used at 5V using a level shift is advised. 

## UART RX (in) 

Data is received by ZETAPLUS20 on this pin. A 50ms timeout exists to avoid lock-up if not all required data bytes are received - in this scenario the packet would be aborted and no data sent. 

## UART TX (out) 

Data is output from this pin ZETAPLUS20. 

When in receive mode and an RF packet is received the data is automatically sent output on this pin.

## Ping-Pong (Walk test) 

Using two ZETAPLUS20 module a test signal can be sent to ‘Ping’ ‘Pong’ between the two providing a site check of signal strength for a specific application. 

In this mode one ZETAPLUS20 transmits a special ‘Ping’ signal, which is received by another ZETAPLUS20 module which outputs the message #RZYXWVUTSRQ (#R followed by the last 10 letters of the alphabet in reverse) to its host, and then automatically reply's back the ’Pong’ message. The originating ZETAPLUS20 module receives back the ‘Pong’ and outputs #T followed by the received Signal Strength Indication (RSSI) value. 

If no ‘Pong’ reply packet is received back from the receiver within 200ms the RSSI value will be 0. 

## Transmitter 

The example below sets the ZETAPLUS20 to transmit a ping signal. The transmitter will output every 200ms the RSSI value of a valid packet through its UART RX pin. 

## ATT#000 

## Channel number (byte value) 

The below screen shots shows a terminal window and the received data on the RX pin. The image shows the data packet that is output when a successful ping-pong takes place on the transmitter. The below image shows the values output by the transmitter during the walk test when no packet is received back from the receiver.

## Receiver 

To configure the ZETAPLUS20 into receiver mode for the ping-pong walk test, the following string needs to be input on the TX pin.

Channel number (byte value) 

10 byte payload (this is the only byte value that will force the ZETAPLUS20 into ping-pong) 

The image below shows a terminal window with a successful packet received, here you can see the HEX values for #RZYXWVUTSRQ (This being RSSI followed by the TEN BYTES and the #R showing receiver).

DS-ZETAPLUS20-a 

## ZETAPLUS20 RF Transceiver 

## Communication with the ZETAPLUS20 via SPI interface. 

Maximum SPI data rate: 1.4Mhz 

Data is sent over the SPI bus on the ZETAPLUS20 codec in standard SPI format using the correct command set. A 50ms timeout exists to avoid lock-up if not all requested data bytes are sent - in this scenario the packet would be aborted and no data sent. 

When in receive mode and an RF packet is received the U_IRQ pin will go low indicating SPI data is ready to be read. 

The following two pages show example timing diagrams for the SPI bus communication. 

## Selecting preferred communication method. 

Only one communication method can be used at a time. Switching from SPI to UART and vice versa is possible however please note that ZETAPLUS20 will respond using the comms that it was last addressed in. 

For example if you enable receive mode via SPI ZETAPLUS20 will revert to SPI communication from there on unless you access the device via UART ZETAPLUS20  will then revert to UART communication from then on. 

Note: SDI and SDO from the Master device not the ZETAPLUS 

Above is the first byte of SPI data following U_IRQ going low after an RF packet has been received. 

Sequence:- 

1. IRQ goes low indicating a packet has been received. 

2. Read byte over SPI bus. 

3. If IRQ remains low then more data is still available to read. Repeat line 2 above. 

The first two bytes read should be #R followed by the packet length & RSSI value then the packet data.
