The Offset+ and Offset

functions allow you to conﬁgure an offset value, which allows an easy way to switch cameras. To conﬁgure the Offset+

and Offset

functions, complete the following steps:

1. Assign the Offset+ function to a user-deﬁnable control key on the CM9760-KBD keyboard. Refer to the Setting the Control Keys Function

section of the CM9760-KBD Keyboard Installation/Operation manual for instructions. Select Offset+ from the list of functions.

2. Assign an Offset+ value (using the deﬁne number icon) to the user-deﬁnable control key. To switch to a new camera, this value will be

added to the camera number that the operator is viewing.

Example: If the Offset+ value is 1000, then when the operator is viewing Camera 1, pressing the Offset+ key will switch to Camera 1001.

(The new value must be a valid camera number; if not, the camera does not switch.)

3. Assign the Offset

function to a user-deﬁnable control key on the CM9760-KBD keyboard. Refer to the Setting the Control Keys Function

section of the CM9760-KBD Keyboard Installation/Operation manual for instructions. Select Offset

from the list of functions.

4. Assign an Offset

value (using the deﬁne number icon) to the user-deﬁnable control key. To switch to a new camera, this value will be

subtracted from the camera number that the operator is viewing.

Example: If the Offset

value is 200, then when the operator is viewing Camera 1000, pressing the Offset- key will switch to Camera 800.

(The new value must be a valid camera number; if not, the camera does not switch.)

If your system uses an optional analog connection between the Endura camera (through the Endura encoder) and the matrix switcher, you can

use the alternate cameras feature as an easy way to switch from live analog video to digital recorded video.

When a system is installed with an analog connection, you need to deﬁne the following camera logical numbers in the CM9700-MGR:

•Matrix Camera: This corresponds to the analog signal. For example, if you connect the ﬁrst Endura camera (through the Endura encoder)

to the ﬁrst input on the matrix switcher, the physical number is 1 and you might assign logical number 1 to this camera deﬁnition.

•Endura Camera: This corresponds to the digital signal, available through the Endura network and the CM9700MDD-EVS. As an example,

you might want to assign logical number 5001 to the ﬁrst Endura camera.

Using these examples, you would be able to view video from the ﬁrst Endura camera by selecting either logical number 1 (for the analog

signal) or logical number 5001 (for the digital signal).

1. Once you have added the Endura cameras to the matrix system conﬁguration, click one of the matrix cameras, such as logical camera

number 1, from the example described above.

2. Click the Alternate Cameras ﬁeld in the camera property box. The Alternate Cameras dialog box opens.
