RF-TRP-4BUTTON (SET)

Wireless Interface of Buttons (switches) to the BrightSign with Phoenix GPIO connector

Note: Antenna Included!

• 'LOCAL' Receiver (1.8 x 1.8 inches)
• Remote' Transmitter (1.75 x 2.6 inches)
• Compatible with all Brightsign models that have a GPIO port with Phoenix connector.
• Local Receiver is Powered by the BrightSign
• Remote Transmitter requires 3.3V external power (2.1mm jack provided)
• On board LED's to indicate Power and Processor running and state of GPIO I/O's
• Data communications using a RF module designed for High Reliability!
• Working Distance about 300 feet (100 meters)

This board set is used to 'remote' interface 1 to 4 buttons (switches) to control a BrightSign.

Order adapter TB12-DB15 for connection to legacy BrightSigns with DB15 GPIO connector

Fixed address.  Contact HMS Electronics 'Technical Support' if you require custom addresses due to close proximity of wireless sets!

Operation:

The 'Remote' unit begins transmitting when any GPIO pin on the remote board goes low (switch or 'button' closure).  It transmits continuously (every 20 milliseconds) the state of the GPIO pins as long as any pin in low.  When all GPIO pins are high, then the remote transmitter transmits 'all gpio off' 2 times.  Then the remote unit goes back to standby waiting for any GPIO to go low.

The 'Receiver' (connected to the BrightSign) drives 1 to 4 of the GPIO pins low corresponding to the transmitted 'GPIO byte' from the remote.  The receiver connects to a Phoenix terminal block (not provided) and plugs into the back of the BrightSign.

Note: The transmitter receiver 'TRP' modules have LED's to indicate the state of the module.  When transmitting the Remote unit 'Red LED' is on.  When receiving the 'Local' Green LED is on.

Note: For reliability the communication consists of 3 bytes.  Address, GPIO byte, Checksum.  This protocol improves reliability and provides for custom addressing if required.

Note: The 6 pins of the 'Local' board can be connected to a 6 pin or to a 12 pin Phoenix connector.  The upper GPIO's (4 thru 7) can be used if plugged in to the BrightSign connector in that manner.

Note: Order the phoenix connector seperately!

Important: Do not connect 5V to either transmitter or receiver.  The BrightSign supply 3.3V via the GPIO connection.
