Description

This receiver gives you four relay outputs with a contact rating of 8 amps at 240VAC. The relay mode can be set to momentary or latching.
The user can select 8 different narrow-band frequencies and program an unlimited number of transmitters to the receiver. With a narrow band FM 151MHz signal from the transmitter a line of sight operating range of 5000 meters is possible. The receiver uses a crystal oscillator circuit that ensures high-frequency stability allowing optimal performance in the receiving range.

Output Modes
Relay output on the receiver can function in either momentary or latching mode. By default the mode is set to momentary. Modes selectable from the 4-way dipswitch. Dipswitch 1 corresponds to relay channel 1 and dipswitch 2 corresponds to relay channel 2 and so on.

Factory Default = Momentary

• Momentary – Output is active for as long as the transmitter button is pressed.
• This is a standard mode on most automatic gates or garage door openers.
• Latching – Output remains active until next press of the transmitter button.
• Similar to switching “on” and “off” a light.

Customized Software

• Custom output modes can be programmed to do special functions. Contact Elsema for more details

Coding
The 12-way dip switch on the receiver sets the 12-bit unique code for the system. This has to be matched to that on the transmitter. Do not use the factory default code.
Apart from the 12-way dip switch, there is an additional 1 way dip switch :
This 1 way DIP switch on the right side of the 12-way dip switch denotes the channels. See the table below.
Generally to use a 4-channel Tx to 4-channel Rx to match all the 13 dip switches (12way + 1way just on the right side of the 12 way).
To use an 8-channel Tx to control 2 x four channel Rx match all the 12 dip switch and switch 13 “OFF” on the first Receiver and switch 13 “ON” on the second Rx.
To use 4 x single channel transmitter to control a 4-channel receiver, match all 13 dipswitches and change dip switch 14 & 15 on the transmitter as per below table.

Signal Strength Indicator
The 151MHz receivers have green signal strength LED’s on the board. The table below indicates the level of the valid transmitted signal.
