Installing the MERLIN Identifier System
Connecting a PC
Instead of the Printer
A PC running asynchronous communications software can be
used instead of a serial printer to capture Caller ID information
from the MERLIN Identifier Control Unit. If you are using an
Administrative PC, the same PC can be used if it has a free serial
port or you install a switch box.
The PC can be situated in the same room as the MERLIN
Identifier Control Unit or located in another room. If you want to
locate the PC in another room, you will need to install a jack near
the MERLIN Identifier Control Unit and another jack near the PC,
and run an inside wire between the two jacks before using the
procedure that follows.
To connect a PC to the MERLIN Identifier Control Unit, follow the
steps below:
1.

and switch off the PC.

Controller Serial Port Only” to the MERLIN Identifier Control
Unit port labeled “Serial Printer.”
Connect one of the following adapters to the PC’s serial port:
