C) Getting garbage text or lines not refreshing on Crestron Touch panels:

If you are using an X-Series processor, you are most likely overflowing the buffer (255 Bytes) that

goes with the internal serial port. It is HIGHLY recommended that you use a 2 series processor. If

this is not possible, you may find some improvement by using a CNX-COM2 card.

D) The text is being drawn slowly on the touch screens:

If there are a lot of touch panels attached to one control processor then make sure you are using an

“Indirect Text Broadcast” to send the serial data out to the touch panels. This does a broadcast of

serial text to all of the touch panels instead of sending each line to each touch panel individually.

**NOTE: This will not work with more than one AudioReQuest since the join numbers are used for

both units. The only fix in this case is to use different joins for each AudioReQuest and duplicate the

pages on the touchpanel.

E) When I go into the ARQ pages on my touch panel nothing happens:

1. Verify that you are pulsing the START-SERIAL-COMMUNICATIONS signal when you select the

ARQ from your source page

2. Try to navigate on the panel. Occasionally after a program or touch panel is loaded, the indirect

text doesn’t update automatically.
