one of the connector, normally where the

Loop in communication cable.
Port 1 (Com 1) is used as communication

The cable is marked with "Hardware halt"
at the end with the loop. The mark is on the
cable or with a yellow sticker on the

software transfer procedure may not be
possible.
The communication cable is shown on the
spare part CD, pages M302.
