CONNECTING THE
HUB
[SiNET™ HUB 444]
All connections between the PC, the hub and the Si™ drives are
made using four wire cables with RJ11 connectors. These are the
same cords used to connect a telephone or modem to the wall jack.
A small black "modular adapter" that allows the RJ11 cable to
connect to the serial port on your PC is also required. A modular
adapter is included with each Si™ drive.
Longer cables can be used but do not exceed 50 feet.
Note: never connect the
HUB
[SiNET™ HUB 444]
to a telephone
outlet or to the modem port of your PC.
Note: if making your own cables, make sure that the ends
are terminated just like a telephone cord, as shown below.
Not following this procedure can seriously damage the
hub, the drives, or your PC. If in doubt, purchased cables are
highly recommended.
