Bc2000 (for the BCF2000 & BCR2000)

I am fairly new to MIDI and have been trying to have my BCR control my JX-8P.  I've read the various manuals, posts, and experimented a lot, but am having trouble getting the two connected.  I've probably missed something obvious and am hoping that someone can help.  I read the answer to a previous question about using a DAW to direct the synth to the BCR, but I'd like to be able to control my synth in stand-alone mode.

I have the BCR connected to my computer via USB.  The firmware is current at 1.10.  The connection to the JX is:

JX MIDI out > BCR MIDI in > BCR MIDI out > JX MIDI in

First, I downloaded the JX-8P profile from this site.  Using BC Manager, I sent the profile to the BCR.  After the send, my BCR lights changed on P-16 and P-32.  I believe this indicates a successful upload.  All the BC Manager testing indicated that the BCR was recognized and connected.

Next, I set the JX to receive on MIDI channel 16 and used P-16 on the BCR:

MIDI button on JX > edit slider to 16 > Write

However, the BCR does not seem to be communicating with the synth.  Turning knobs doesn't change the tone,  nor does the JX display change.  What have I missed?  Thanks in advance for your help.  Once I solve this, I feel that I can get my JV-1080 connected as well.
