Thanks for the response. I just got back from a trip and see this message.
I did perform the test you mentioned in the email. I used the hyper
terminal program to determine that the problem is lack of echoed characters.
What is your advice on fixing this?
If it is not easy to fix, I would like to purchase either a new IR tower or
a RCX. Is there any new version of hardware or software going to be on the
market soon? If yes, is it worth the wait of buying the up coming new
version?
Thanks,
Wendy

Some advise and suggestions.
Post to 'lugnet.robotics' and not 'lugnet.off-topic.test'. You're likely to
get better response.
Are you sure your new batteries all work? Test them out as follows:
- Does the green LED briefly 'flash' on the serial tower during the
diagnostic test? If not, then 9V battery needs to be replaced.
- Does the RCX beep and display '1' in the LCD program slot when you turn it
on? If not, then RCX needs new batteries.
If tower and RCX are not properly pointed towards each other, communication
will not work. [I know this is obvious, but try some different
combinations]. In particular, make sure tower isn't set for long range
transmission (switch on front) and RCX is within a meter or so. I find short
range transmission setting on tower and RCX about 1.5 feet away works fine.
I'm not familiar with the download and test software that you have been
using but it sounds to me like problem might be in the tower. With the
serial tower, every outgoing byte is also echoed back to your PC where it is
discarded; I think this is a byproduct of IR transmission 'leaking' into the
IR receiver on the tower. A decent diagnostic routine would know this fact
and look for the echo-ed characters. If so, I would interpret "IR
Transmitter Fail" message as a lack of the echoed characters. A way to test
this is to use one of a PC "console" program to type characters on COM1 port
and look for echo of these characters.
Hope you get your system working.

| Wendy, Dick, I'm fighting the same issue on a RIS 1.5. I haven't resolved the problem yet but let me share what I've found. Character echo means only that you've connected to the IR tower. Using hyperterminal, I get perfect echoes, but I get them (...) (22 years ago, 10-Jan-03, to lugnet.robotics)
