Phone lines are connected to the back of the unit using modular jacks. Input and output ports are provided for wiring systems using either 2 wire connections (RJ11 > 1 phone line per phone cord) or 4 wire connections (RJ14 > 2 phone lines on one phone cord). If the wiring coming into your building does not terminate in modular jacks, contact your telephone vendor to add modular connections.

The supplied six foot, 9 pin serial cable connects the unit to an available serial port on the computer. If the computer has a 25 pin serial port, a 9 to 25 pin adapter can be purchased at any computer or Radio Shack store. Additional monitoring units are connected to one another using the same type cable. Please refer to page 13 for more information on connecting multiple units.
