I've connected the USB to Serial adapter but it's on Com Port 5 (or higher) and your software only has Ports 1-4. This issue applies to the c\temp software only. This has been resolved with the new version of the MDAS-Pro software. If you do not have a copy of this software, please contact us.

Many new PCs (especially laptops) have USB ports but do not have the standard 9-pin serial ports found on older computers. This presents a problem because most of the GPS manufacturers don't make data cables that terminate with USB plugs. Unfortunately, we have noticed that the USB-Serial converters often cause computer crashes. We are working hard to resolve this problem.

USB to Serial Support - Use a direct/single USB to serial cable, and stay away from multi-port "hubs". Unplug the serial cable to the weather station when changing PC connections, like from serial jack to USB jack. Power down the weather station before connecting the serial cable.

Yes but you must purchase a USB to Serial converter. We have the IOGEAR USB to Serial Port Adapter Model GUC232A available under RIGblaster Accessories. All of the software was written for serial port control so it will not work directly with a USB port. With the USB to RS232 serial adapter you can add the function of a serial port to a computer that doesn't have one or doesn't have and extra one.

Yes, because the SignaLink doesn't require a connection to the computer's serial port! Unlike other interfaces, the SignaLink never requires a serial port connection. This is particularly handy if your computer doesn't happen to have one! In addition to simplifying your installation, this feature also reduces the likelihood of the computer's RF noise getting into your radio. It also eliminates serial port related transmit problems that plague other interfaces.

The serial port should be located on the back of your computer. An example of a serial port image is provided here.

A#8.9: This answer describes hooking up a terminal to the printer port. Hooking one up to the modem port will be similar except that .ttya should be used instead of .ttyb. On the hardware side, you will need a mini DIN 8 to DB25 printer cable. This should be connected from the IIgs' printer port to the port on the terminal that would normally be hooked to a modem. Next, you have to run a getty(8) over the printer port. Add this line to your /etc/inittab file: pp:23478:rest::/usr/sbin/getty 8bit.

A#8.15: This is usually caused by serial port configuration problems. Common symptoms may be: % copycat .ttyco .ttya Error opening tty .ttya, aborting. or % /usr/sbin/getty 8bit.38400 .ttya getty: .ttya: I/O error The first thing to check is that the following GNO serial port drivers exist: /dev/modem /dev/printer Next, ensure the following two lines are in your /etc/tty.config file, and that they are uncommented: modem 2 .ttya printer 1 .

Just connect the serial TxD (transmit-data) and SG (signal ground) lines to Backpack pins SER (serial) and GND (ground). These are standard header pins on the Backpack circuit board. The Backpack accepts either RS-232 levels or TTL/CMOS.

A - You can add a Serial Board or a Multi-Port Board (with serial ports) to add more serial ports to your PC which cost as very little . Or you could use a (Serial) Switch box to connect two devices to one serial port.

If you can spare even one hour a week, you will be able to start the process. This approach will take longer than if you throw yourself into it wholeheartedly; however, if you don't start, you will never get there.

Some unnamed clone cards have also been known to work, especially those that claim to be AST compatible. USB device support was added to FreeBSD 3.1. However, it is still in preliminary state and may not always work as of version 3.2. If you want to experiment with the USB keyboard support, follow the procedure described below. Add the following lines to your kernel configuration file, and rebuild the kernel.

For Unix, see a Usenet post by Mitch Chapman: http://groups.google.com/groups?selm=34A04430.CF9@ohioee.com

It's system-dependent. Under Unix, you typically open, read, and write a device file in /dev, and use the facilities of the terminal driver to adjust its characteristics. (See also questions 19.1 and 19.2.) Under MS-DOS, you can use the predefined stream stdaux, or a special file like COM1, or some primitive BIOS interrupts, or (if you require decent performance) any number of interrupt-driven serial I/O packages.

It allows the application to interface to the GPS receiver through the same interface (commands and logs) as an external controller would through a physical com port.

The serial port is a 9-pin D shaped connector, similar to the video connector except with less pins. Usually, there are two on a PC. One may possibly be in use by the mouse (mainly on older machines). They are also referred to as Com ports or Communications ports. They are identified in Windows as Com1, Com2 etc. Look in the device manager under "ports" and you will see if you have any set up - if not, you may have to enable them in you motherboard's bios via the CMOS setup utility.

Answer: Three serial ports are provided. One can be used for external control from a modem or other serial device. The other ports can connect to managed serial devices (such as routers, PCs, servers, or other RS-232 devices). Port 3 is the default control port. Ports 1 & 2 use the PC standard DTE pinout, with RXD on pin 2, and TXD on pin 3 of the male DB-9. Port 3 has TXD on pin 2, and RXD on pin 3 of the female DB-9. Port 3 offers hardware handshaking; ports 1 & 2 do not .

No, but it is much more convenient. Most ham radio sound card software can control your PTT via a serial port. If your software doesn't have serial control, unlikely, or you don't have a serial port connected, you can use all of the RIGblasters with your radio's VOX. In that mode the sound card audio is fed to your radio and your radio's VOX circuit will activate transmit.

The 10-pin header next to the dip switches is a 2nd serial port. You can hook this up to your PC's serial port (with a null modem), and get connectivity that way, utilizing the 'qtalk' app on the i-opener. This seems to support zmodem, but the i-opener doesn't seem to have the sz/rz binaries. If it did (or if you can find/FTP them), it might make an easy way to transfer files to/from your PC.
