Automatic Serial Data Collection


Automatic Serial Data CollectionAs more and more devices come equipped with some type of communication for data collection and monitoring, the amount of data that can be collected by a PC in a system is astounding. A problem arises, however, when multiple instruments or devices need access to the PC through the serial port, but only one port is available.
There are multiple options for expanding the capability of a port that was designed to communicate with only one device. You can add a separate serial port for each RS-232 device that you need to talk to. By adding serial ports, multiple devices can have their own dedicated port, often concurrently and at high speeds. The drawback is that separate serial ports may be expensive and require some effort to configure. There is also a practical limit on resources available inside the PC to allocate to Serial Ports.
Multiple devices can be tied together by converting the signal at each point to a multi-drop bus, like RS-485. This allows up to 32 devices on a single network without repeaters. The devices can also be connected up to 4000 feet away from the PC. The disadvantage is that each device must have its own unique address. Also, some protocol needs to be established to prevent more than one device at a time from sending data to the PC. Usually this is done by having the PC poll each device individually. This does not lend itself well to devices that send their data automatically, without being requested.
Using the 232BSS4 buffered Smart Switch is an excellent way to collect data from multiple devices utilizing RS-232 serial ports. Up to four instruments, card readers, or time clocks can be directly connected to the 232BSS4, providing access through a single serial port on your PC.
If you have more than four devices that are sending data, more than one 232BSS4 can be cascaded, allowing more ports to be added. The 232BSS4 buffers data from all ports at once, making it well suited for devices that will send a fixed amount of data at sporadic intervals, such as measurement instruments, security access card readers, barcode scanners, or time clocks. Below is an explanation of how best to utilize the 232BSS4 to connect these devices to your PC.>
232bss4_setup.gif
Figure 1
>Figure 1 shows a typical setup, with 16 devices sending information at random times to the PC. The switches at Level 2 receive the data and send it on to the Level 1 switch. The Level 1 switch buffers the data and sends it to the PC. Each of the switches will automatically send the data when it is available. If another port has access to the PC, the data will be buffered until a path is available.
Cascading in Automatic mode:
For best results in an automatic system, the 232BSS4s in the system should be set up the following way.
  • Set the switches to turn on the AutoSelect feature.
  • Set the Port Timer to 0
  • Set the Inactivity Timer on all of the switches to somewhere between 50 and 500 milliseconds, depending on the space between data packets and the response time required to each connected device.
  • If you need your software to identify which port sent the data, set up the port preamble on the Level 2 switches. Set each port to have a unique preamble. The preamble can be 1, 2, 3, or 4 characters long, and any characters can be used. The preamble will be added to the beginning of each new data packet arriving at the PC. The data collection software on the PC should be written to recognize this preamble as an address or identifier of the data source.
Cascading in Polled Mode
This configuration will also work with systems where the devices have to be polled for information. With the setup of Figure 1, the switches can be configured so that you still only have to send one set of switching characters. To do this, set the switches up in the following way:
  • Set the switch on Level 1 to broadcast to all slaves on startup.
  • Set the switch on Level 1 to AutoSelect mode, no preamble.
  • Set the switch on Level 1 for 0 Port Time
  • Set the switch on Level 1 for a short Inactivity Time. Somewhere around 5 milliseconds or so.
  • Set the switches on Level 2 for no AutoSelect.
  • Set the preamble on the Level 2 switches to be unique from each other. One suggestion is to use a 3 character command. Use the first character as a start of command character like STX. The second character could represent the address of the Level 2 switch you are going to. The third character is the command character.

I have an Hp Pavillion a170n System by can't


Go to Printers . Put curser over the Printer icon . Press Right button on mouse . Go to bottom of meue PROPERTIES> when open at top menue selct ports. Configure port. other approach deleat printer and reinstall new printer. during set up will ask what port. USB sometimes uses virtual printing Ports. Another aproach is if USB ..Just pull cable from computer and stick in some other USB port forcing computer to reload driver to that port.

Tv set up


The port you're looking for looks like this:

0ee3505.jpg

It's called an SVHS or stereo VHS output port, and with an SVHS cable should be able to be plugged into a cable box.

Note that this is a ONE WAY PORT - it takes a signal FROM the notebook, not TO the notebook. If you want to view television pictures on your notebook you will need further hardware. This port is only for viewing your computer output through a television or other device.

Port forwarding


hi there,
this is a basic step used to forward ports to your system.
Port Forwarding Steps for Routers 1. Log into your router. Usually the URL is http://192.168.1.1/, and enter the username , and the password . If you have never set a password, the password (which you should change) is admin. Consult the manual if you have never set up your router before or need to reset the password. 2. Click on the "Applications & Gaming" tab or Under Advanced, click Port Forwarding.
3. Click on the "Port Range Forward" tab .
4. In the "application" field, type "web" (if you are forwarding wb traffic on port 80) or "torrent" (if you are forwarding bittorrent traffic on port 40156). This is just a "nickname" so that you can recognize what you were trying to do when you come back to it.
5. In the "Start" field, enter: 80
6. In the "End" field, also enter: 80
7. Set "Protocol" to TCP. Web and Bittorrent servers use only TCP, so there's no reason fo forward UDP traffic too and create an unnecessary security risk.
8. In the "IP Address" field, enter: 192.168.1.11 or your system IP address.
9. Click "Save Settings." Forwarding should begin immediately.

sometimes the usb ports are not set to auto connect so you have to find them manually.. if you goto start then to my computer you will see all your ports and find the one that you are trying to use then right click on it and make sure the settings are set to run a disk once it's inserted..

you can also goto start then run, if using xp, and browse for that usb port that way too.. let me know if this helps at all, if not, i can try something else.. you can do a repair on your ports too but let's see if this helps.. good luck..d
