Internal Plug-in Sensor Connection (NDA…THS version)
If your display delivery includes internal plug-in temperature and humidity sensor (NDA…THS version)
insert the sensor device into the opening hole in the bottom side of display frame. To ensure proper
electrical connection the connector of the sensor must be inserted all the way in. The connector type is
3,5 mm Jack.
External Sensor Connection (NDA…TH version)
If you purchased external sensor “THS Sensor 52 12DC RS485” as an optional accessory, your display
includes input connector for this sensor.
External sensor has a 4-wire cable with EUROCLAMP connector already preinstalled. Plug this connector
into its corresponding connector “P1” (green color connector) located on the PCB board. All PCB
connectors are accessible on the back panel of large size LED display under a small door plate. The door
plate is secured by two screws which must be removed first. Once you remove the door plate, attach the
sensor cable connector into its corresponding PCB connector. Then insert and screw the door plate back
again. Use the slots in the door plate to route the cable. External temperature/humidity sensor is powered
directly from the large size LED display. No additional external power supply is necessary.
LAN Ethernet TCP/IP Communication Connection
LAN communication is performed via standard Ethernet TCP/IP protocol. Socket RJ45 is located on the
PCB board under a small cover door plate on the back panel of large size LED display. The door plate is
secured by two screws which must be removed first. Once you remove the door plate, attach the LAN
cable connector into its corresponding PCB connector. Then insert and screw the door plate back again.
Use the slots in the door plate to route the cable.
You can plug standard CAT5 type LAN cable from LAN network port (e.g. switch or hub) directly into this
socket. Please see table below for pinout description.
