If you experience problems that aren't covered below, it would be helpful to us and to your fellow pilots if you could email us with information on the problem, and on the cure or workaround if you have one.
Some people have reported having problems getting AOL's browser to perform the authentication procedure. So far, we have the following info on what works and what doesn't:
Microsoft Internet Explorer version 2.1 supplied with Compuserve version
2.5 on CD does not work. However, Netscape 3.0 using the same Compuserve
connection works well. Therefore, the problem seems to be the browser and
not Compuserve itself.
If you encounter this problem, try loading a later version of Hyper Terminal from the Hilgraeve site. We found "Private Edition" Version 2.0 to work. As of March 2001, version 6.1 is current, and it's still free.
When you start Hyperterminal, the globe on it's "splash screen" (startup screen) appears to rotate. If you don't see this effect, you must upgrade to a more recent version.
Additional Hyperterminal Hints
It is a good idea to copy your data files to your computer's hard disk. It appears that pauses caused by reading a floppy disk can sometimes cause problems.
If you have to change the baud rate in Hyperterminal, we have found that sometimes you will get "gibberish" on the computer screen after doing so. If you exit and re-enter Hyperterminal, it then works correctly. Once the computer and Argus are communicating, save the "connection" with its own icon and name. Then you will only have to click on that icon to re-establish the connection.
When you have established the Hyperterminal connection, the screen will show a series of characters which slowly gets longer. When this occurs, click on "Transfer" and then "Send File." Select 1K-Xmodem as the protocol and type the name or select using "Browse" the file to transfer, followed by Send. The transfer will proceed automatically from there.
If you have connected the computer to the Argus and appear to be receiving no response at all, there are three possible causes (apart from incorrect setup, covered elsewhere in this section).
1: Computer problem
2: Cable problem
3: Argus problem
It is possible to determine which with the aid of a paper clip (or other small metallic object such as a key). The goal is to establish a connection between the Argus and the computer with the cable. If the computer isn't sending, the cable isn't connecting, or the Argus isn't receiving, nothing works. Here's how you can tell where the problem lies:
Remove the cable from the computer's COMM PORT (usually 9-pin) connector, and, using a paper clip, short pin 2 and pin 3 of this connector together. (The pins are usually numbered in tiny print inside the connector.) While doing this, type characters on the computer keyboard. If you see the characters echoed on the computer screen when the short is present, and not echoed when the short is removed, then you are getting data in and out of the COMM terminal. If you don't get this behavior, then perhaps you are using the wrong COMM port, are having a problem with the Hyperterminal software, or suffering some other computer malfunction. As this is strictly a computer problem, there is little we at Eventide can do to help fix it.
If the computer passes the test, reconnect the cable at the computer end and remove it at the Argus end. Again using the paper clip, short the "tip" and the "ring" of the miniplug together. (The tip and the ring will be obvious. Be careful not to also short them to the "sleeve.") Type on the keyboard; you should see the same behavior as above. If the screen does echo without the cable and doesn't echo with the cable, you probably have a defective cable assembly. Call us and we'll exchange it.
Note that the cable can be a tight fit. Factory-supplied cables can be inserted properly. However if you are using a homemade cable, it is possible that it isn't being fully inserted. If it doesn't bottom in the Argus connector with a satisfying click, you may have to unscrew the barrel or otherwise get it to fit.
If you are getting data through the cable but the Argus still doesn't respond after going into the data transfer mode, double check that the baud rate and other parameters are correct, the Argus baud rate is set the same as the Hyperterminal, and that the "Hardware Handshake" parameter is set to NONE or OFF. Clean the cable plug that goes to the Argus, and insert and remove it a few times. If it still doesn't work, the Argus may be defective, in which case we will have to service it.
The software I use is ProComm Plus. I have a 3Com Palm V hooked into my laptop Com1 serial port. A user must "disable" the Palm V in order to update the Argus 5000. Otherwise, the computer looks for a "Hotsync" operation and does not recognize the Argus 5000 during a data base update.
To disable the Palm V, go to the Palm Desktop, click on HotSync, click on Setup, go to the General Tab and disable "Always available (put in Startup folder)" by clicking on "Available only when Palm Desktop is running."
This might save somebody else who uses a pocket organizer with their
laptop several hours of effort.
Once the transfer starts, it will normally run to completion. Most programs, including Hyperterminal, indicate transfer progress, including percentage complete, and show an error count of retransmitted packets. Normally there will be no transmission errors. If there are one or two it may indicate a slightly noisy connection but is no cause for concern. However, if you accumulate a large number of packet errors, the transfer may abort early or take longer than it should. If you have gotten to the point where this occurs, the problem is most likely hardware related-you've done everything right. Here are some things you might try:
