Hi,sir

The sys light is down,you can see whether there is a ttl interface on the board.If not, you can only contact sales team for repair.

yes theres a ttl light blinking on the interface equivalent to the boards

Have you tried dario's suggestions?If the problem persists,you need usb-ttl cable,this is the manual:https://www.openvox.cn/pub/misc/tools/Flash%20Voxstack%20Gateway%20Board%20with%20USB-TTL%20cable.pdf,you can add my skype: live:.cid.40c135e80b21dc4 to talk.
