Connecting the Hub
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. You’ll also need a small black “modular
adaptor” that allows the RJ11 cable to connect to the serial port on your PC. A
modular adaptor is included with each Si™ drive.
You can use longer cables, up to 50 feet. Telephone line cords are easily available
at your local supermarket, discount or electronics store.
Note: never connect the SiNet hub to a telephone outlet or to the
modem port of your PC.
Note: if you decide to make your own cables, make sure that the ends
are terminated just like a telephone cord, as shown below. If you mess
this up, you could seriously damage the hub, your drives or your PC. If
in doubt, don’t make your own cables.

Sinking Circuits (NPN)
If your output devices prefer to sink current, then connect the “+” terminals to your
positive power supply, and the “-” terminals to your signals. If you are using a TTL
circuit to drive the hub inputs, connect the “+” terminals to your 5 volt bus. No
ground connection is needed. If you are using a PLC or proximity sensor, you’ll
need a power supply.
Sourcing circuits (PNP)
If your output devices can only source current (some PLC outputs are this way),
connect the “-” terminals to the ground of the DC power supply that powers your
output circuits. Then connect your signals to the “+” terminals.
Note: We refer to an input as being ON or CLOSED when current is
flowing through the input. A signal is OFF or OPEN when no current is
flowing. An input is OPEN when the “+” and “-” input terminals are at
the same voltage, or when the input is left unconnected.
Programmable Inputs
The Hub444 provides four digital inputs for external equipment such as sensors,
switches and other electronics. These inputs are optically isolated, and allow a
wide range of input voltages to be used. Each input gives you the option of using
sinking or sourcing signals.
A schematic diagram of the input circuit is shown below.
You must supply 5-24 volts DC to supply current to the LEDs on the input side of
the optoisolators. Most CMOS and open collector TTL devices are directly compat-
ible with this drive, as are typical PLC and proximity sensor outputs.
