Connection sequence
for cradle in network:
Set all cradles to the same baud rate (by
DIPswitch)
Only 1 cradle in the network will be
connected to the PC through one RS232
cable. On this cradle the DIPswitch for RS232
connection must be enabled. Through this
connection all cradles can communicate to
the PC.
A maximum of 16 cradles can be connected
in a network through RS485 cables. For the
cradles that are not directly connected to the
PC the DIPswitch for RS232 connection
must be set to off.
The first and the last cradle in the network
must have the termination resistors set by
dipswitch.
