Address: Enter the keyboard address. The address must match the address specified by the keyboard DIP switch settings.
Idle Disconnect (sec): (Optional) Enter the number of seconds of inactivity you want to elapse before VMX300(-E) closes the COM port
(direct serial connection) or the local port (IP connection). The port will open again automatically when a new
connection is established with the relay unit. Use the default value of 0 to indicate that the port should never be
closed while the driver is running.
Note that the following fields should not be changed:
Poll Interval (sec): This field is reserved for future development.
Connection Attempts: This field is used for troubleshooting and should specify the default value of 3.
Attempt Interval (sec): This field is used for troubleshooting and should specify the default value of 30.
Comm Timeout (msec): This field is used for troubleshooting and should specify the default value of 1000.

USING THE KBD300A LOGICAL MAPPING FEATUREWhen operating a KBD300A keyboard, a user must use camera numbers and monitor numbers to control these cameras and monitors. Since the
VMX300(-E) system is based on device names, you must use the “Enable the device number” field in the Edit Local Settings dialog box to assign
a number for each device. However, no two device numbers in the VMX300(-E) system can be the same (for example, you cannot use device num-
ber 1 for both a monitor and a camera).
To provide system operators with a simple numbering scheme, such as one that would allow the operator to observe “Camera 1” on “Monitor 1”,
use the KBD300A logical mapping feature.
The KBD300A logical mapping feature allows an operator to control devices using numbers mapped to a specific keyboard. For example, if an
operator could switch “Camera 1” to “Monitor 1,” “Camera 2” to “Monitor 2,” and so on.
