Recent versions of the DM-33512 Digital Matrix boards used in TRX-NXT-
512x512 routers have additional input equalization for improved HD per-
formance; these boards are identified with “Pre-emphasis Added” stickers
on the J421 headers used to connect the two halves of the board. If these
stickers are present, and you are operating with Broadlinx 2.4 software or
newer, DIP switches S401-7 and S401-8 (on both boards) should be set to
On; if the stickers are not present, these switches should be set to Off. The
remaining six switches on S401 are always set to Off.
