ATEN CS-102 - Manual (Page 6)

Three Stage Installation
Adding a third stage enables one CPU Switch (the first stage CS-104 or CS-106) to control computers directly or indirectly
via cascaded CPU Switches (the second and third stage CS-102, CS-104 or CS-106). The number of PCs under control is
determined by the configuration.
Fig. C
1. Set DIP switch 4 of the first stage CPU Switch to ON and all others off.
2. Computers may be connected to the first stage, the second stage, and the third stage CPU Switches. 5-pin DIN
connectors are for AT style keyboard sockets; 6-pin mini-DIN connectors are for PS/2style keyboard sockets.
3. Use either keyboard port per computer.
4. To connect the keyboard ports of two CPU Switches, use the 5-pin DIN ports only.
Note: 1. Add a power adapter if the CPU Switch works abnormally.
2. Neither the PC1 or PC2 port of a CS-102 or CS-122 can be connected to a CS-104 or CS-106.
3. For PS/2 users: You must connect a PS/2 mouse, because a serial mouse can not replace a PS/2 mouse. For
cascaded operation, connect PS/2 mouse ports of successive stages using a 6-pin mini-DIN male-to-male
cable.
