3.1. Wireless Distribution Network The USR-C216 serial server can be configured either as a wireless STA or as an AP. So USR-C216 logically supports two wireless interfaces, one as STA, the other as an AP, and the other STA can connect to the wireless network through AP interface of the serial server. -
Page 13: Work As Sta
3.1.3.Work as AP+STA USR-C216 can support one AP interface and one STA interface simultaneously. After opening the AP+STA function, the STA and AP interfaces are available at the same time. The STA interface of the serial server is connected to the router and is connected to the server in the network through TCPB, and the AP interface can be connected by mobile phone / PAD (through TCPA). -

C216 supports search in-LAN. When C216 is connected to a wireless router, users can obtain the IP address of the serial server in C216's current LAN by sending UDP broadcasts to a fixed port to realize device search and communication. It can also directly connect C216's AP to send search instructions. Jinan USR IOT Technology Limited www.usriot.com... - Page 20 Note: Search tools and C216 must be in the same LAN. If multiple STAs are connected to a router, the computer running the search tool is also connected to that router. This search tool can search all the STA.
