    (The EZL-80c serial port has a 1-kbytes reception buffer and 512 bytes transmission buffer.) The serial port hardware flow control of EZL-80c is implemented RTR(ready to receive)/CTS (clear to send) protocol. The RTS port (RTR is called RTS in EZL-80c for convenience) is an output port that becomes „active low‟...

    At position „C‟ the counterpart sends a signal that it is ready to receive data. At this time, EZL-80c has any data to send, it sends the data to the user‟s processor. At position „D‟ EZL-80c sends a signal that it is ready to receive data. Now both the parties send and receive data.

    4. WIRELESS LAN CONFIGURATION 4.1. The Types of Wireless LAN 4.1.1. Infrastructure The infrastructure is a network connection mode that allows communication between wireless LAN devices or between the wireless LAN and the wired LAN (Ethernet) through the Access Point (AP). When a network type is set to infrastructure, communication with wired LAN via AP is possible, which allows both wired and wireless Internet communications.

  • Page 16: Configuration Parameters For Wireless Lan

    Configuration Parameters For wireless LAN 4.2. 4.2.1. Service Set Identifier (SSID) When configuring a network, the user can configure different networks using different Aps. In this case, the SSID is used to differentiate one network from another. In other words, when configuring an infrastructure network, the user can make communication with the AP which he/she wants to communicate with by setting the SSID of the desired AP in the ezTCP.

If a network-attached ezTCP is detected, the following message will be displayed. If a message pops up indicating that there is no response from ezTCP, check that the power is turned on and the cable is connected correctly, then try pressing [PROBE] or [READ] button.
