Input/output, or I/O, refers to the communication between an information processing system (such as a computer running Symphony), and the outside world (possibly a human, or another information processing system such as an access control system).
Inputs are the signals or data received by Symphony, and outputs are the signals or data sent from it. Alarm inputs include Video Motion Detection from network cameras and external I/O devices. To set up rules for I/O devices, see Rules.
Symphony supports ADAM, Phoenix, Axis Camera I/O, and PSA devices.

1. Log into the server. Click Devices>Hardware.
2. Click the Add button for one of the hardware devices.
3. Depending on the I/O device type selected, various fields are displayed. The main options typically are:
IP address - If an IP-based I/O device is configured, enter the IP Address of the device.
Module - Select an Advantech model (6050, 6060, 6066) from the drop-down list.
Registry Entry/Controller Number - For Phoenix. Field populated by default.
COM Port and Baud Rate - If an I/O device is connected to the serial connection of the server, you must configure the COM Port address and Baud Rate properly.
4. Failover enabled: Specify whether the device will automatically move to a redundant server under a failover condition.
If Failover is enabled, this device can move to another server in the farm during failover.
If not enabled, then the device cannot be moved. Any device that requires access to resources available only on a single server (for example, COM port, special SDK or drivers) is unmovable.
5. In Symphony client, activate (or deactivate) each output as necessary in the Camera Tree by right-clicking on the hardware name and selecting Change IO State.
