SS 4x4 Installation and Operation Manual
INSTALLATION
Connecting Two SS 4.4’s To A Single Computers Serial Port
Multiple SS 4.4’s may be cascaded serially to operate from the same serial port. The
first step is to assign unit ID’s to each SS 4.4. One suggestion is to assign unit ID 1
to the first SS 4.4 and unit ID 2 to the second switcher. The second step is to paral-
lel the serial ports of the SS 4.4’s. Plug the male end of the duplex modular adapter
into the supplied female (S9) DB-9 to RJ-11 adapter, then attach the supplied mod-
ular line cords into each of the duplex modular adapter receptacles (Radio Shack Cat
No. 279-0357) and the other ends into each SS 4.4 modular receptacles. See the dia-
gram below. NOTE: Three or more SS 4.4’s may be daisy chained by using the
above description and a Radio Shack Cat No. 279-0410, 5-jack modular adapter.
