Configure EXM448-1 as slave

Hello.

For EXM448-1 you need to use @CSPRO instead of @PRODP. Configure the correct address (MAA) and slave functionality (SLA=1 or 2). You should use the same CRV/CTV at EXM448-1 side, but the difference is at connectors AT/AR at address stage 1. You should configure 0 at address stage 1 instead of partner address, as EXM448-1 operates as slave, e.g. AR='CHAN.0.1', AT='CHAN2.0.1'. General description about configuring SS52 as slave you can find at this manual, chapter 3.5.
