After setting up and adjusting the gate travel, everything works as expected. One significant issue I had to work thru with the support staff at Topens was the inconsistent operation of the TC196 WiFi Remote that works via your smartphone. Although my indoor setup is well within the 230 meters from the gate controls (mine is about 50 meters at the most), the operation was inconsistent. It may work one day and not that afternoon. After several exchanges with Topens support, they suggested an external antenna ( https://www.desertcart.com/dp/B094MW1YMV/) that has fixed the issue. One additional tip I would offer is when you are setting up the TC196, the "paring" sequence MUST be done as fast as possible. It appears the main board only has a few seconds to press the momentary switch on the main board, then press "A" on phone, have lights flash and press "A" on phone again. It took me multiple tries to get it programmed. Again, after solving the issues with the TC196, all the operations of the gate and related components appear to be working as expected. Thanks again to the support at Topens for assistance in getting everything working! Review: highly recommended - Works great and as described, highly recommended if need more than 8 remotes. ## Features - Safe Connectivity - TOPENS ERM12 External Receiver effectively receives signals from TOPENS wireless access devices, such as remote control and keypad. It transmits signals to the gate opener, triggering the gate to open or close. With advanced TOPENS code technology, ERM12 establishes a reliable and secure link between the gate opener and remote control devices. In addition, the external receiver can be used to extend the operating range of TOPENS wireless control accessories. - Pair up to 250 Remotes - Simple wire connection makes installation labor-saving. Just connect the ERM12 to the gate opener system. Program the M12 Remote Control (incl.) with ERM12 universal receiver, and then the M12 remote will make the gate operate between open-stop-close-stop-open. All TOPENS swing and sliding gate openers can be operated by the M12 remote. ERM12 rolling code external receiver can be programmed with up to 250 pcs TOPENS M12 remote control transmitters. - Wide Compability - Works with all TOPENS gate openers. It can be powered by the control board of the gate opener or by the external 9-24VDC power source. Kindly note that ERM12 receiver ONLY works with TOPENS wireless remote control accessories. - Clever Design - The external receiver is suitable for household, courtyard, farm, ranch, warehouse and other commercial / industrial sites. Weather resistant for all seasons of the year. Made of high-quality UV-resistant, flame-retardant and durable materials, the waterproof receiver works in bad weather conditions. Please note that the ERM12 external receiver works with the gate openers only, and does not support other door access control systems. - Customer Service and Technical Support - All the TOPENS products come with a 12-month war-ranty against defects, a 30-day exchange & return and excellent tech support.
