DTS RX3 Operating Instructions Manual

OPERATING INSTRUCTIONS - DTS RX3 THREE CHANNEL RECEIVER

General Operation:

a) The 3 channel receiver will operate with a 12 to 24V AC or DC supply. The relay
contacts are rated at 1A/125VAC or 1A/30VDC and are intended for signal switching
only.

b) The receiver memory will hold 31 remote transmitter keys in combination between the
3 channels, with or without full code hopping decryption.

c) Relay operation is indicated by the Red channel LED. Momentary or latching mode is
selected by the channel option jumper (jumper link fitted for latching / not fitted, for
momentary mode).

Adding a Transmitter Key to the receiver:

1. Press and release the “Learn” push button to cycle through the output channels until
the required channel is selected (indicated by the red channel LED). The Green RX

LED will be on, indicating that the “Learn” mode is active. The “Learn mode is
enabled for only 5 seconds. The receiver will exit “Learn” mode if there is no activity

within this period.

2. With the required channel selected, press and release the remote transmitter’s push
button. The receiver will cancel “Learn” mode if the remote transmitter key is already
programmed into the receiver memory. On reception of a valid key, the red channel
LED indicator will switch off and the steady green RX LED will change to rapid
flashing. A further press and release of the remote transmitters push button is
required to validate the key entry (minimizes the possibility of inadvertently
programming unwanted keys).

3. Successful entry and programming is indicated by one of the following methods:

a) Two simultaneous flashes of the selected channel red LED and the green RX
LED Indicating that a non registered key has been successfully entered and will
be decoded without code hopping decryption but with serial number decoding
only.

b) Three simultaneous flashes of the red and green LED indicating that a
registered key has been successfully entered and will be decoded with full code
hopping decryption and synchronization.

Removing a Transmitter Key:

1. Press and hold down the “Learn” push button and release immediately after 5
seconds when the green LED turns on. The green LED indicates that the “Erase next

key” mode has been activated. Press and release the required remote transmitter

push button to erase that key. Successful erasure is indicated by all the LED’s

turning on for 1 second.

2. The “Erase next key” mode will self cancel after 5 seconds if no remote transmitter
key has been received or will cancel immediately if the received remote transmitter
key is not in the receivers memory. Repeat step 1 for erasing additional keys.

Total memory erasure:

1. Press and hold down the “Learn” push button. After 5 seconds the green RX LED will
switch on. Continue holding the push button for a further 5 seconds and release

when all the LED’s start flashing. All LED’s will pulse together 5 times indicating total

erasure of the receivers memory

General Indications:

a) A self test procedure is performed when the receiver power supply is connected.

Successful initialization is indicated by 1 short flash of all LED’s. 5 short flashes will

indicate that the receiver’s memory is totally erased.
b) Rapid flashing of the red LED while adding a new transmitter key indicates that the

receivers memory is full (31 keys stored). If this 32nd key is saved, the user must be
aware that the 1st key saved will be discarded. Additional new keys saved will discard
older keys on a “first in / first out” cyclic basis.

c) Rapid flashing of the green RX LED when the remote transmitter push button is
pressed indicates that the remote transmitter battery is low.

Note:

The indications and operation of the DTS RX1 Single channel version receiver is the
same as above.
