  • Q: Does the Neets Switching Relay - 4 protect the screen from the possibility of getting mains on both sides of the engine at the same time? (Mutual blocking)
    A: Yes, this feature is built into the hardware, if you use the dedicated screen connections.
  • Q: How do I easily adjust the end stops for the screen?
    A: You can use the test buttons to manoeuvre the screen up and down to ease the adjustment.
  • Q: Why are there odd cut-outs in the printed circuit board?
    A: They are used for cable ties to relieve the cables.
  • Q: How do I control the Neets Switching Relay - 4?
    A: The Neets Switching Relay - 4 can be controlled via RS-232, LAN or I/O ports.
  • Q: How do I update the firmware of Switching Relay - 4, if the firmware is newer than 3.6.3?
    A: Open Project Designer and press update to ensure you have the latest firmware downloaded, then connect the Switching Relay - 4 to a computer via USB, and then a box appears if there is a newer firmware than the one in the device.
  • Q: How do I update the firmware if the firmware is 3.6.2 or older? (Only relevant for products bought before August 2015)
    A: Connect the Switching Relay - 8 to a computer via USB, and the box should show as a drive in file explorer.

    Now swap the file on the drive with the newest firmware from our website. In the future, the relay will update automatically when connecting to Neets Project Designer. Be sure you have updated the Project Designer software before starting the process!
    Note: This can only be done form a computer running Windows 7!
  • Q: What is the default Baudrate of a 4-Relay?

    Baudrate: 19200
    Data bit: 8
    Stop bit: 1
    Parity: None
  • Q: What is the default LAN settings of an 4-Relay?

    DHCP: off
    LAN speed: 100 Full duplex
    TCP port: 5000
  • Q: How do I set the Neets Switching Relay - 4 IP address?
    A: This is done with the RS-232 on port 1 by sending the following command:
    NEUNIT=1,SETTINGS=LAN,IPADDRESS=192.168.1.100
    where the UNIT ID of your relay is 1, and 192.168.1.100 is the IP address you want to set.
    Remember to send a save command to save your settings for when the power is off.
    The save command is: NEUNIT=1,SAVE=TRUE
    See the protocol list in the manual for further network settings you can alter.
    means Carriage Return Hex=0D
  • Q: How does RS-232 loop-through work?
    A: Connect your control panel to the RS-232 port 1 and any sequence sent to this port with an id number different from itself will be retransmitted on port 2.
  • Q: What is the internal power supply for?
    A: You can use the PSU to power your Neets Control System, which will then make the PSU that comes with the control system obsolete.
  • Q: How can I tell if the Switching Relay 4 is the new improved version?
    A: Locate the serial number, new range are starting at 1732XXXXX and upwards.
