Class 3&4

• RJ-45, connector cable. Standart connector for ethernet. The oldder xports are needed 3.3v data beside 3.3v power. So what we can do is, put a 3.3v diode band on it facing above the ground.
• IPv6 is a new network layer that expands IP numbers as we use today.
• RS232 operates on voltage levels between -5v to -12v to create logic 1 and 5v-12v to create logic 0. But since our chip runs on 5v at most, we need an interface to connect TTL with RS232. We use MAX3223 chip for that. In PicBasic we use SEROUT2 16468 because of that where USB handles this command by itself.
• Xport operates on TTL levels, thus it does speak with TTL and inverted. Check before it you are getting 3.3v to the xport connector. We don’t want to waste our xport. Gateway for NYU:128.122.151.1.
• so we need an usb to ethernet to connect the xport and setup. We can do it couple of ways, using arduino without its Uc, or using Max3223. Netmask should be 8 bits, change telnet config password to N, transmit of Uc is transmit of USB device.
• channel 1 is serial port on the device. -> I/F mode refers to what we have in zterm N1/8. Its called special function registers, space of memory that controls preferences through special functions.
• Flow control - zterm, we check off the float control. I’m sending data, you are processing data and you’re overwhelmed by the amount of it, so you say, “no I don’t want no more data.”
• Port no is 10001, connectmode is what xport tells us when we connect to it. D4-> We use D4 for it.
• Remote IP is remote ip if we want to connect xport to remote host, remote port is the remote port. Discon Mode is default, flushMode flushes serial buffer. DisConnTime could be handy in times where you want to save energy. It disconnects your xport when in idle for certain amount of time.
• SendChar 1 (00) default.
• By using control right square bracket and Q and return. -> We can disconnect from Xport after we connect it. -Should try this!
• C 128.122.253.189/80 -> Command for connecting to xport.
• Loopback addres, in order to use we need a listener callled, to listen that port. Loopback happens in the xport if we use 127.0.0.1 but we need to connect to the IP address of the macbook. We use ethernet cable instead of Airport to connect to the server. It is less secured because it is wired, it is more safe.
• So remembering what he did in the class, he ran an processing application of a chatserver running on the macbook. That said, he tried to connect to it serially through an xport.
• C 128.122.151.128/10002 To serially connect to the xport.
• If you want to access your xport preferences through a web interface, you can use your assigned ip address on the browser.
• There is a small application written in Arduino which connects it to xport. This program returns 3 bytes in return, character, return feed and new line feed. If we change the Serial.println(inByte, DEC); we can return ASCII values.
• We are aware that technology is affecting our lives in positive and negative ways, that said, if we are aware of it, we can position ourselves on it better than the people who are not aware of it, we can question what we want to change about it, what we can change about it.
• Mostly the whole technology is mediated, We developed manners about phone when it is invented, we developed new manners when answer machines arrived, but we still haven’t developed manners about the technology that is here, coming. We should design next level of technology in the approach that we need to guide them how to give them(users) options. We do have agencies for most of everything. Those information agencies sometimes works and sometimes doesn’t works.
• For next week, try to think about an information agency which involves in a risky situation and may misread your unintentional actions and what would you feel about it?
