Hello, new member here. I’m old school, 70 years old. But still building things. I bought two 2ch -REM to control 2 linear actuators. If I hold the buttons on both remotes neither actuator moves, release one and the other will move. I must be able to move each actuator at the same time. I tried using a separate battery, rather than wiring both actuators to 1 battery. This project is a rubber tracked machine powered by a 25hp gas engine and driven by 2 hydro-gears. The actuators run the hydros , pulling less than 5 amps. Thanks for any help. Richard
Hello @staffman49 !
Great to see you here. I did some research and I just found this video tutorial. Also, I’ll leave you the datasheet showing how the connections should be.
Hope this could help you! 
I have two of the 2CH-REM hooked up but can not control both actuators at the same time. I even tried a separate battery for one side. If both remote are pressed at the same time, nothing moves, must release button from one remote before other remote will work. Look under remotemowers.com then go to remote control conversion kit. This is how I need mine to work but I hate to pay over $900.00 for it. Thanks for any help. Richard
