  1. Orchaidman: FYI, (DevMike if stepping on toes, please advise) LOR uses the RS-485 Serial protocol system, they opted for Cat5 cable and ends because they where 1) easy for the user to get parts for custom cables, and 2) the board connectors are "off the shelf". 3) the twisted pair in cat5 is the perfect mate to RS485. RS-485, like I said, is a Serial communication system HOWEVER, it is very different from the common RS-232 (On most older computers). RS-232 uses a multi wire control system to deliver and receive data, Tx/Rx CTS, RTS, Ground, and V+ (5v) many people discard the CTS and RTS, and use only the basic 4 wires, BUT, RS-232 has a limit of cable length of a mere 150 feet (thereabouts), where as RS-485 (with correct cable termination resistors (120 ohm, each end) can EASILY do 4000 feet ! on twisted pair !!! There in lies the HUGE difference in the two RS standards. RS-485 uses common mode "DIFFERENTIAL PAIR" (2 wires), it can be used on normal 4 wire telephone cord, BUT, if it is NOT twisted pair, (the silver cord with the wires side by side is a good example of NOT twisted pair) it gets "spastic" around 200 feet, the twisted pair in Cat5 cable is the other half of the robust and very reliable communication system of RS-485. Rather than using the 232 standard of dots and dashes on a 5 volt signal level, 485 uses 12 volt differential signalling BETWEEN the pair (the out/in of the system uses a floating reference and the two wires swap voltages to indicate digital data. because the twisted pair acts as a common mode filter system, the entire cable "ACTS" as if it was a shielded cable (when you twist the wires, they form a pseudo-shield for the opposite wire in the pair) RS-485 is used in Industry for huge machine sensors and control, for data loggers & time keeping system. In cars the "CANABUS" data system is a 2 wire RS-485 system (even though the industry does NOT want people to know that). RS-485 is one of the most robust signal transfer methods I have seen or dealt with in my 50+ years in electronics. Greg Manning
  2. Totally Understand, offer still stands.
  3. JR, sorry for your Loss, if there is anything I/we can do, please let us know. Greg/Judy
  4. DevMike... IF I only had the money.....
  5. OK, I guess I should Clarify my requirements.... My display is narrow and WIDE (some 400 feet worth), and running servo dogs, just isn't practical. I want an ONLY 3 wire connection system (+,D and -), other than than the lights on the moving part (THAT will still be in CTB-16's) By using a MC-6850 UART, as the "Output section" and addressable MC14469 dip switch addressable uarts, I can run a receiver wherever I need, along that 400 some odd feet of display. the 14469's can be had for under 5 bucks a piece. a latch IC, and a D to A for timing pulse width to the servo, or I could go larger cheaper Steppers with a Stepper motor driver. as some of the props I want to move are quite heavy and large.
  6. Greetings All, hope everyone got what they wanted at the Sale yesterday. I am working on a interface system, that would produce movable props using the same protocol (RS-485) as LOR does, for the lightshow, Think of it this way. it is a simple X and Y axis control system so you could move say as an example, a wireframe deer head, or a spot light (like they do in concerts). Just wondering if there is other people that would find this of interest, or am I the only one. Replies, very welcome. Greg
  7. Almost sounds like you are talking vacuum tube amplifiers or something...
  8. Control the kids going into a show.... :)
  9. FWIW, Linux 19.1 cinnamon, with the Tessa desktop, running an older version of Windoze XP in a virtual box, is rock solid, the Linux is state of the art, and dam FAST, and windoze XP is a great version (IMHO) better than 10 any flavor, Linux, is FREE............... Greg Manning
  10. Jerry.. Sorry to hear about your Accident, Remember though, ANY show, small , large, or somewhere in between , IS A GOOD THING !! It's the fact that that one is done, NOT the size of it !!! Keep up the great work ! Greg Manning
  11. did a quick check.. everything else I'm following, I\m the last post, so that would make sense, as to why I' ony gett the 4 words one... DUH !
  12. LOL, ARE you saying the people that own a WTCPR and a WTCPN are old ??? LMAO !! guess I fall into that category... (even have the DE-soldering head adapted to the WTCPN). Greg 不不不不不
  13. only notifications I've been getting are for the "continue the story in four words", here in the coffee shop, nothing else.
