1. Before You Start

The Y412 is designed for fast deployment with minimal setup. In most projects, you only need to complete four steps:

  1. Confirm the model and channel count (22, 44, or 88).
  2. Connect power and antenna.
  3. Set the channel (DIP switches 1 to 5, identical within the same communication group).
  4. Set the operating mode (momentary / latching + unidirectional / bidirectional + master / slave).

2. 3-Minute Quick Start

Step 1: Power On and Basic Check

  • The POWER LED should stay on.
  • Any lit RSSI LED indicates that a wireless link has been established.
  • The red OUT LEDs show the output status of each channel.

Step 2: Keep the Channel Setting the Same

  • DIP switches 1 to 5 must match on Device A and Device B.
  • It is recommended to validate the default channel first, then change it if required by the site.

Step 3: Select the Operating Mode

  • First decide the master/slave role: only one master is allowed in each network.
  • Then decide the control direction: unidirectional feedback or bidirectional follow.
  • Finally decide the output action: momentary or latching.

Step 4: Verify with Local Push-Buttons

  • Press a local key on one device and check whether the corresponding OUT LED changes on the remote device.
  • Validate one channel first, then test the remaining channels.

3. DIP Switches and Modes

3.1 DIP Switch Definition

  • 1 to 5: channel setting (32 channels total)
  • 6: momentary / latching
  • 7: unidirectional / bidirectional
  • 8: slave / master

3.2 Typical Mode Examples

3.3 Mode Description

  • Bidirectional follow: both master and slave can trigger the remote output.
  • Unidirectional feedback: the master typically drives the slave, while the slave returns output status feedback.
  • Latching: each short press toggles the output state on or off.
  • Momentary: the output stays on only while the input is active.

4. Typical Wiring

4.1 Power Wiring

  • DC version: V+ / V- / PE
  • AC version: L / N / PE

4.2 Digital Input Wiring

Supports 2-wire switches, 3-wire switches, and 3-wire sensors.

Scenario A: Remote Start/Stop Control

  • Mode: Unidirectional + Latching
  • Use case: pumps, fans, and lighting circuits
  • Benefit: local push-button action and remote output state remain easy to understand

Scenario B: Press-and-Hold Operation

  • Mode: Unidirectional + Momentary
  • Use case: loads that should operate only while the button is pressed
  • Benefit: reduces the risk of unintended maintained output

Scenario C: Two-Way Mutual Control

  • Mode: Bidirectional + Latching
  • Use case: controlling the same type of equipment from two separate locations
  • Benefit: both ends can operate as a control point

6. Troubleshooting

  • Check whether DIP switches 1 to 5 are exactly the same.
  • Check whether there is only one master in the network.
  • Check whether the antenna is tightened and whether any RSSI LED is on.

2. Input Changes but Output Does Not Switch

  • Check whether the device is in momentary or latching mode.
  • Check whether the load is wired correctly to DO COM and DO NO.
  • Check whether the channel indicator LED turns on.

3. The System Works but Disconnects Occasionally

  • Increase antenna height and reduce obstacles.
  • Switch to a range-priority configuration.
  • Enable timeout reset through the host-side configuration tool if needed.

4. More Advanced Settings Are Required

  • Use the configuration tool through RS485 or serial communication to read and write parameters.
