Product overview
The Linsn CN901 is an RJ45 signal repeater for extending the control link between an LED sending card and receiving card. The V1.1 manual describes a typical 100 m extension per relaying card and identifies two signal indicators plus a power indicator.

Plan the cable run
The 100 m figure is described as a usual extension, not a guaranteed result for every cable route. Check cable quality, connectors and the sending/receiving hardware, then test the complete link at the required distance.
The manual does not state a maximum cascade count, total link distance or weather-protection rating. Confirm those requirements for the intended installation instead of multiplying the typical extension into an unlimited link.


Frequently asked questions
1. What does CN901 do?
It relays the LED control signal to extend the link between sending and receiving cards. It is not a video source or an LED pixel-capacity upgrade.
2. How much distance can one CN901 add?
The manual says one relaying card usually extends the link by 100 m. Actual performance should be checked with the installed cable and endpoints.
3. What do the three CN901 LEDs indicate?
LED1 corresponds to the nearer network port, LED2 to the farther port, and LED3 indicates power.
4. How many CN901 repeaters can be cascaded?
The linked V1.1 manual does not specify a cascade limit. Confirm the supported topology and total distance before planning multiple repeaters.
