1. LIMITATIONS
a.
All the slave units must be the same size (4, 8 or 16 port)
b.
Up to 8 slave units may be connected to form a maximum system size of 128 ports (1x8 port master + 8x16 port slaves).
c.
Slave units must be added to the master unit in order (slave #1 to master's port 1, slave #2 to master's port 2, etc).
NOTE: Master Unit Port 1 (with an 8-port Slave Unit connected to it) will become ports 1-8 (1-4 for a 4-port slave, 1-16 for a 16-
port, etc.). Master Unit Port 2 (with a second 8-port Slave Unit connected) will become port numbers 9-16 (5-8 for a 4-port slave,
17-32 for a 16-port slave, etc.).
d.
All units must be powered OFF during configuration and interconnecting.
e.
For a Master Greater than 8 ports, only the first 8 ports may be configured for the Master/Slave option. The remaining ports
on the master are numbered from the last port of the last slave. Note: In a 1x32 Master w/8 1x8 slaves (8 slaves being the
maximum number allowed),ports 9-32 on the Master would become ports 65-88.
2. CONFIGURATION:
All units are configured using the 8-position switch (located on the front of each unit) according to the tables below (2-4):

3. CASCADED INSTALLATION
a. Configure each switch as per above tables before proceeding.
b. Perform steps 1 & 2 under INSTALLATION for each slave unit.
c. With a SUCEXT-xx cable, connect slave #1 monitor port to master's CPU-VID 1 port.
d. With a SUKINT/SUKEXT-xx-MM cable, connect slave #1 keybd port to master's key 1 port.
e. Repeat steps c. & d. for each additional slave unit, keep in mind that each slave will connect into the next
available master's port (i.e. slave #2 to master's vid-2 CPU & key-2, etc.)
f.
With a RMT extension cable, connect master's RMT out port to slave #1's RMT in port.
g. With another RMT extension cable, connect slave #1 RMT out port to slave #2's RMT in port.
h. Repeat step g. until all slave units are connected together.
i.
Repeat the installation section of the manual for any CPU's to be connected to the master.
NOTE: If you are using an optional wired remote, it will be connected to the master switches RMT IN port.
