Terry,

One of the reasons that the uninstall and clear out the program directory
may be needed now and then is that the many upgrades may miss deleting some
of the old parts for one reason or another. So the software will work with
'add on' packages like CATS, when it runs it loads what it finds. If
something had been left around over time, it could get loaded and interfere
with the newer correct parts.

At this point your descriptions and logs show the LocoBuffer is our major
suspect. Here is a clip from the manual about testing the LocoBuffer. Give
it a try and see if that helps to confirm it working or not.

6.1 Sanity Test

To perform a very basic LocoBuffer-USB sanity test perform the following

steps:

1. Unplug the LocoNetR cable. Disable the internal LocoNet terminator if

enabled. (remove any internal jumper at "Term")

2. Power up the LocoBuffer-USB by plugging it into the computer.

3. The lower green power LED should come on.

4. Plug in the LocoNetR cable. The upper green power LED should light.

5. Unplug the LocoNetR cable. The red activity light should blink briefly as

the cable is removed.

6. Restore the termination jumper to its original position if used.

If the lower green power LED does not light, be sure that the USB drivers

have been properly installed. The LocoBuffer-USB does not power up

until the drivers have properly enumerated. (installed and started up)

If the Rail Sync upper power LED does not light, or if the activity LED

does not blink when you unplug the LocoNetR cable, be sure that your

DCC command station is powered up, then check your LocoNetR wiring.

To further test the LocoBuffer-USB you may also perform the following

Loop Back test.

6.2 Loop Back Test

The LocoBuffer-USB input circuit and code actually reads from the unit's

LocoNetR output jack, so if you send a character it should be seen on the

input This test uses the free software available from the JMRI project to

watch the test commands. (www.jmri.org)

Steps:

1. Open the JMRI LocoNetR Monitor window.

2. Using a throttle send a speed change to a locomotive.

3. The set speed commands should appear in the LocoNetR monitor

window and the LocoBuffer-II activity LED should blink

4. Using JMRI send some commands (e.g. switch commands)

5. The commands should appear in the LocoNetR monitor window and the

LocoBuffer-II activity LED should blink

If there is no activity light when throttle commands are sent, check the

LocoNetR wiring. If there is no activity shown in the LocoNetR monitor

window, check that you have LocoBuffer-USB selected in the JMRI

preferences, or that you have LocoBuffer selected and are running at

57.6Kb. Check that you have the correct COM port selected.

Emailing RR-CirKits may be helpful and Dick and Karen are good with
responding to email.
