![]() Again I have to thank Mike Hewett for reminding me of wirewrap. My original test bed connections were done with what is call "Dupont" wires. These are nothing more than wires with push on connectors on each end. Nice and easy to use but prone to coming loose. Good for prototyping. Mike showed me some of his work using wirewrap. When I started in the computer design business in 1970, wirewrap was still common and acceptable even for production work. Look here : National Advanced Systems. Mike used a hand wirewrap tool but I had a couple very old Gardner-Denver wirewrap guns. I dug them out and replaced the long dead rechargable battery with 2 D cells and I was off. I used the small green proto board from MPJA.com as a base. |

First, as a review, look
at the "Serial Ports" tab. You may have seen this before because this
is how to tell RTC which USB serial port to use for the Radio and RFID
detectors. This tab works just the way it worked back when it was the
only option possible. You can press the [Scan] button to find all of the available USB serial devices on your computer. Click on the [X] Enable button and use the up/down arrows in the spinners to set the port number. I still use a wired USB port for the Radio communications. I have developed RTCModemWiFi to do this over WiFi but the wired USB is simplier to use. In this window, I have selected COM11. This setup window also lets you choose a wired connection to the RFID tag detectors - but now the WiFi connection is a much better choice. Continue reading. |

Now if you are going to use WiFi, you have to have built up one or more of the ESP8266 devices described above. Click on the "Host IP Address" tab. Press the [Scan] button. If only one Ethernet interface is present on your computer, the IP address for that interface should appear in the drop down box. If it does not or if you have to select from several IP addresses, do that so that the correct IP address appears. The vast majority of home computers only have one Ethernet interface so it should rarely be necessary to make a selection. |

Now click on the "WiFi Ports" tab. Here is where we do the heavy lifting. If you have created one or more, RFID detectors, enable the RFID WiFi by clicking on the [X] Enablebutton next to it. You don't have to do any selection as the RTC program and the RFID detectors will find each other. RTC can communicate with up to 254 RFID detectors over WiFi. Note that WiFi routers usually have a limit on the number of WiFi devices that can connect. I have 8 tag detector ESP8266 on my layout so I had to make sure that my router could connect to 8 WiFi at the same time. You may have other devices also connected to WiFi (like printers, cell phones, etc) so you have to take this into account. |

If you are using ESP8266 based AIU Emulators. You have to enable them here. Click on the [X] Enable button. The IP address of 239.255.200.3 and port of 8890 should not be changed. I've included this window for information only - I don't think the AIU Emulator is ready for prime time yet. If you want to use it, send me an email. |
