Two RDU40 connected to the same REX
If two RDU40 are to be installed to the same REX one of them has to be
"slave" while the other is "master". The slave cannot be configured or
controlled individually but follows the master. Only the LCD-contrast can
be individually controlled at the slave.
To make an RDU40 work as a slave it is necessary to move the jumper at
the RDU40 cover to position 2 according to Figure 1-1.
