Antenna Installation Instructions
The antenna interface of the single-channel edge intelligent terminal is an SMA female socket. Screw the SMA male connector of the matching antenna onto the sensor acquisition edge terminal antenna interface and ensure it is tightened to avoid affecting signal quality.
Antenna placement guidelines are as follows:
(1) Keep as far away as possible from large metal surfaces and the ground;
(2) Ensure the antenna has line-of-sight as much as possible;
(3) Minimize obstacles between antennas;
(4) Shorten the feed length between the antenna and the module as much as possible.
The effects of different antenna installation methods are shown in the diagram below.
Indicator Light Description
The IEP3000-6 series multi-channel thermocouple temperature acquisition terminal is typically used in complex external environments. To adapt to complex application environments and improve system stability, the IEP3000-6 multi-channel temperature acquisition terminal adopts advanced power technology. Users can power the terminal with a standard configured 24VDC/1A power adapter or directly supply DC 7V~30V to the acquisition terminal. When using an external power supply, the power must be stable (ripple less than 300mV and instantaneous voltage not exceeding 30V) and have a power rating above 10W. The temperature acquisition terminal provides four indicator lights: "Power", "RUN", "COM". The indicator statuses are as follows:
