Connection
with external devices and systems is made easier using serial communication.
Examples of external devices are printers,
access systems, alarm systems, or video
equipment. Furthermore, serial communication offers a wider variety of uses
than simple relay triggers from external equipment. For example, some external
systems may capture and analyze serial messages to determine the best action.
Serial communication offers many
benefits like extended system capabilities and minimized connection costs.
- Collection of logged items.
- Connection
to an external modem.
- Direct remote control of external systems.
-
Connect to an alarm monitoring point.
Connecting Door Controllers Together
There are many methods for
connecting door controllers together in a system. With increasing awareness and
use of TCP/IP technology, networking controllers using this technology provide
advantages in speed, distance between controllers, and the number of
controllers within the overall system.
Reducing Installation Costs
By using a serial connection hardware connection costs are
minimized, while initial system configuration costs may be a bit higher.
