MCR91512SS
12 Channel Receiver with 12 Open Collector Outputs| MCR91512R
12 Channel Receiver with 12 Relay Outputs
Description
The receivers use fast frequency hopping (FFH) to allow up to eight receivers
to be used in the same area. No interference or jamming will occur. The FFH
technology is usually used in very expensive equipment with military or
medical applications.
The receivers use a dual digital coding called Multicode Technology (MCR).
This MCR digital coding can be either the 12-way dipswitch or the encrypted
coding.
The 12-way dip switch allows for simple programming and involves the user
simply matching the 12-way dip switch on both the transmitter and receiver.
The encrypted coding is a randomly generated code that is programmed
wirelessly to the transmitter and receiver. The encrypted code is usually used
when more codes are required for high-security applications. See setup
instructions for more details on the dipswitch and encrypted coding.
The combination of FFH and MCR technology brings you a very sophisticated
receiver yet easy to use.
Connecting Elsema’s ANT915-SMA to the receiver’s SMA connector will increase
the operating range.
Different Modes for each Output
Modes are user selectable from the 4-way dip switch, shown below.
| DIP Switch Mode Settings
The output relay will respond in the following manner when receiving the
correct signal from a transmitter
---|---
| All OFF| “All Momentary”: Relay on, only while the correct signal Is
received
| 1 ON| “All Latching”: Outputs alternate at every correct incoming signal
| 2 ON| “Momentary & Latching”: Outputs 1-8 are momentary & 9-12 are latching
| 1 & 2
ON| “Security Latching on”: Outputs will be on until supply to the receiver is
momentarily interrupted
| 1 & 3
ON| “Momentary & Latching “: Outputs 1-4 are momentary & 5-12 are latching
| 2 & 3
ON| “Momentary & Latching “: Outputs 1-6 are momentary & 7-12 are latching
| 1, 2 & 3
ON| “Security Latching on”: Output 1 & 2 are security latching & 3-12 are
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 the next press of the transmitter
button.
Similar to switching “on” and “off” a light.
Security Latching – Output remains active until power to the receiver is
removed. Similar to security alarms and fire alarms. To activate the security
latching mode, a link needs to be soldered into the hole marked as latching.
Customized Software
Custom output modes can be programmed to do special functions. Call Elsa for
more details.

Antenna
The receiver has a 50-ohms SMA connector to allow a proper 915MHz antenna to
be connected. Elsa stocks the ANT915S-SMA suitable for connection to the
receiver. See the picture below.
Case
The C1217 case and QM100 mounting bracket can be used to enclose the
MCR91512SS receiver into a case.
The MCR91512R only needs the C1217 case since the board screws directly onto
the case screw studs.
The MCR91512SS or MCR91512R can be supplied without a case, this allows the
receiver to be integrated according to your needs.

Application Notes (MCR91512SS)
Care should be taken with the open collector outputs so that they are
protected from inductive loads. This is done by connecting diodes across your
DC inductive load. See diagram below
12-Way Dipswitch Setup Instructions
To program the transmitter to the receiver you simply match the transmitter
and receiver dipswitches. Do not use all dipswitches in the off position. This
sets the transmitter to encrypted coding. See encrypted coding instructions.
To avoid interference or jamming from other MCT series transmitters make sure
that the first 8 dip switches (Dipswitch 1 to 8) are different. The first 8
dipswitches select different frequencies.
Advanced Dipswitch Programming Features
This feature allows the user to configure very sophisticated systems by mixing
and matching different MCT transmitters to MCR receivers.
Dipswitches 9, 10, 11, and 12 will determine the position of the first channel
on the transmitter and receiver.
Other channels are automatically sequentially placed.
| Relay | DS9 | DS10 | DS11 | DS12 |
|---|---|---|---|---|
| Position 1 | 0 | 0 | 0 | 0 |
| Position 2 | 0 | 0 | 0 | 1 |
| Position 3 | 0 | 0 | 1 | 0 |
| Position 4 | 0 | 0 | 1 | 1 |
| Position 5 | 0 | 1 | 0 | 0 |
| Position 6 | 0 | 1 | 0 | 1 |
| Position 7 | 0 | 1 | 1 | 0 |
| Position 8 | 0 | 1 | 1 | 1 |
| Position 9 | 1 | 0 | 0 | 0 |
| Position 10 | 1 | 0 | 0 | 1 |
| Position 11 | 1 | 0 | 1 | 0 |
| Position 12 | 1 | 0 | 1 | 1 |
| Position 13 | 1 | 1 | 0 | 0 |
| Position 14 | 1 | 1 | 0 | 1 |
| Position 15 | 1 | 1 | 1 | 0 |
| Position 16 | 1 | 1 | 1 | 1 |
1 = Dip Switch in “On” position, 0 = Dip Switch in “Off’ position
Example:
Using a 4-channel MCR91504 receiver with a 1-channel MCT91501 transmitter.
If the MCR91504 has 0101 0100 1000 set to the 12-way dipswitch, this sets the
receiver’s first relay (Ch.1) to position 9 i.e. 1000. The other channel
addresses are sequentially placed.
This is shown in the table below:
| Relay Channel | Position | DS9 | DS 10 | DS 11 | DS 12 |
|---|---|---|---|---|---|
| 1 | 9 | 1 | 0 | 0 | 0 |
| 2 | 10 | 1 | 0 | 0 | 1 |
| 3 | 11 | 1 | 0 | 1 | 0 |
| 4 | 12 | 1 | 0 | 1 | |
| 5 | 13 | 1 | 1 | 0 | 0 |
| 6 | 14 | 1 | 1 | 0 | 1 |
| 7 | 15 | 1 | 1 | 1 | 0 |
| 8 | 16 | 1 | 1 | 1 | 1 |
To program a 1-button MCT91501 transmitter to receiver relay channel 4 you
need to set the transmitter’s dip switch to 0101 0100 1011.
To program a 2-button MCT91502 transmitter to receiver relay channels 2 and 3
you need to set the transmitter dip switch to 0101 0100 1001. The second
button on the transmitter automatically operates relay 3
This example is shown graphically below:
Encrypted Coding Setup Instructions
To change the transmitter and receiver to encrypted coding set all dipswitches
on the 12-way dipswitch to the off position. The encrypted code is a randomly
selected code out of 16 million different combinations.
The user can change the code by shorting out the Add/Delete pin on the
receiver. The orange LED comes on while the Add/ Delete pins are shorted, to
confirm the change of code was successful. If this is done all transmitters
and receivers need to be programmed again with the new code.
Any programming combination is possible, for example, transmitter to
transmitter, receiver to receiver, transmitter to receiver, or visa versa.
Programming Steps
-
Make sure all dip switches are in an off position on all transmitters and receivers.
-
Make sure power is connected to the receiver and transmitter.
-
If programming from a receiver, short out the Add/Delete pin to select a random code. The receiver’s orange LED comes on to confirm the change of code was successful. Do not do this step if you are adding extra transmitters to the receiver since already programmed units will be deleted.
-
Set one of the units, either receiver or transmitter, to broadcast its code. The broadcaster’s code will be programmed to the other units.
4a. To broadcast the code of the receiver, make sure all 12 dipswitches are off and then flick dip switch 12 on and then off. This is confirmed by the green LED is on for 10 seconds.
4b. To broadcast the transmitter code, hold down button 1 and flick dip switch 12 on and then off. This is confirmed by the green LED is on for 10 seconds. You can release button 1. -
While broadcasting the code press button 1 on a different transmitter or receiver for 1 second and then release the button. The orange LED will flash twice to confirm successful programming.
Broadcasting will be latched on for 10 seconds or stop if any dipswitch is
turned on.
If the orange LED did not flash twice try programming again but move closer to
the broadcasting unit.
During programming, all channels are channelized and programmed. That is,
button 1 to relay 1, button 2 to relay 2, button 3 to relay 3, etc.
This programming method allows a user to program an unlimited number of
transmitters to the receiver or vice versa. You can even program a transmitter
to a new transmitter. You do not need to get access to the receiver.
Many of the Multicode technology features are industry firsts, so take your time to read the manuals and let the technology take you away. Watch your competitors follow you
