Setting up the SDC 8200 system
Interconnecting the SDC 8200 system components
Depending on the expansion stage of your system, you have to:
yinterconnect the consoles (all expansion stages),
yinterconnect the central units (expansion stage 3),
yconnect a PC to the “master” central unit if the system is to be PC con- trolled.
Interconnecting the consoles
To interconnect the consoles via the system cables:
Connect the black RJ 45 plug of the system cable to the OUT socket of the console.
Connect the grey RJ 45 plug of the system cable to the IN socket of the console.
Note!
You can interconnect up to 20 consoles in one cable string.
Connecting a cable string to the central unit
After having interconnected the consoles, connect the cable strings to the central unit. You can connect up to six cable strings to a single central unit. To connect a cable string to the central unit:
Connect the black RJ 45 plug of the system cable to one of the RJ 45
sockets labelled PORT 1 to PORT 6 of the central unit.
Connect the grey RJ 45 plug of the system cable to the IN socket of the first console of a cable string.
Initialize the consoles as described in the section “Turning on the cen- tral unit for the first time” on page 27.
Interconnecting several central units in master/slave mode (SDC 8200 CU central units only)
You can only interconnect SDC 8200 CU central units. The length of the sys- tem cables between the SDC 8200 CU central units must not exceed 10 m. If you wish to interconnect several SDC 8200 CU central units, we recom- mend mounting the central units into a rack.
To interconnect several SDC 8200 CU central units:
At the first central unit, connect the black RJ 45 plug of the system
cable to the MASTER OUT socket .
If the SLAVE IN socket of a central unit is not connected, this central unit automatically becomes the “master”.
Connect the grey RJ 45 plug of the system cable connected to the “mas- ter” to the SLAVE IN socket of the second central unit.
If the SLAVE IN socket of a central unit is connected, this central unit automatically becomes a “slave”.
To connect additional “slaves”, connect the SLAVE OUT socket of the first “slave” to the SLAVE IN socket of the following “slave”, and so on.
