Basic Functions Basic Functions Overview of Functions VISCA commands are the basis of camera control. Timing Chart As VISCA Command processing can only be carried out one time in a Vertical cycle, it takes the maximum 1V cycle time for an ACK/Completion to be returned. If the Command ACK/Completion communication time can be cut shorter than the1V cycle time, then every 1V cycle can receive a Command. General Commands Command RxD ACK Completion TxD Within 16.7msec(20msec*PAL) Query Commands Within 16.
Basic Functions Zoom The FCB-EX980S/EX980SP/EX980/EX980P employs a 26× optical zoom lens combined with a digital zoom function; this camera allows you to zoom up to 312×. • Optical 26×, f = 3.5 to 91 mm (F 1.6 to F 3.8) The horizontal angle of view is approximately 54.2 degrees (wide end) to 2.2 degrees (tele end). Digital Zoom enlarges the center of the subject by expanding each image in both the vertical and horizontal directions.
Basic Functions White Balance White Balance has the following modes, all of which can be set using VISCA Commands. • Auto White Balance This mode computes the white balance value output using color information from the entire screen. It outputs the proper value using the color temperature radiating from a black subject based on a range of values from 3000 to 7500K. This mode is the factory setting. • ATW Auto Tracing White balance (2000 to 10000 K) • Bright Variable Iris and Gain (Close to F1.
Basic Functions AE – Manual The shutter speed (22 steps), iris (18 steps) and gain (16 steps) can be set freely by the user. When switching from the Shutter Priority mode to the Bright mode, the shutter speed set in the Shutter Priority mode is maintained. AE – Bright The bright control function adjusts both gain and iris using an internal algorithm, according to a brightness level freely set by the user. Exposure is controlled by gain when dark, and by iris when bright.
Basic Functions Exposure Compensation Auto ICR Mode Exposure compensation is a function which offsets the internal reference brightness level used in the AE mode, by steps of 1.5 dB. Auto ICR Mode automatically switches the settings needed for attaching or removing the IR Cut Filter. With a set level of darkness, the IR Cut Filter is automatically disabled (ICR ON), and the infrared sensitivity is increased. With a set level of brightness, the IR Cut Filter is automatically enabled (ICR OFF).
Basic Functions Camera ID The ID can be set up to 65,536 (0000 to FFFF). As this will be memorized in the nonvolatile memory inside, data will be saved regardless of whether it has been backed up. Effect It consists of the following functions. • Neg. Art: Negative/Positive Reversal • Black White: Monochrome Image Others E-FLIP This function turns the video output from the camera upside down. Mirror image This function reverses the video output from the camera horizontally.
Basic Functions Title Display Synchronization methods The camera can be given a title containing up to 20 characters such as “ENTRANCE” or “LOBBY”. The position of the first character (horizontal, vertical) of the title, blinking state, and color can also be changed. Internal and external synchronization are available; VISCA Commands allow you to switch between them.
Basic Functions Privacy Zone Masking Function Features Privacy Zone masking protects private objects and areas such as house windows, entrances, and exits which are within the camera’s range of vision but not subject to surveillance. Privacy zone masking can be masked on the monitor to protect privacy. • Mask can be set on up to 24 places according to Pan/ Tilt positions. • Mask can be displayed on 8 places per screen simultaneously.

Basic Functions Grid Alarm Function Use the grid displayed on the screen to set mask positions (see the figure below). By executing the Center Line On command, only the x and y axes of the center are displayed. Grids lines disappear. This function instructs the camera to detect movement within the monitoring area and then send an alarm signal automatically. A High level signal is output when camera detects movement inside the monitoring area. A Low level signal is output when object stops moving.

Command List Command List VISCA1)/RS-232C Commands This Manual outlines an RS-232 control protocol and command list for certain Sony cameras from which control software can be developed. THIS CONTROL PROTOCOL AND COMMAND LIST IS PROVIDED BY SONY ON AN “AS-IS BASIS” WITHOUT WARRANTY OF ANY KIND. SONY DOES NOT WARRANT ANY PARTICULAR RESULT FROM THE USE OF THIS CONTROL PROTOCOL AND COMMAND LIST AND DISCLAIMS AND EXCLUDES ALL WARRANTIES.
Command List VISCA Communication Specifications assigned address 2 is 82H. In the command list, as the header is 8X, input the address of the camera at X. The header of the reply packet from the camera assigned address 1 is 90H. The packet from the camera assigned address 2 is A0H. Some of the commands for setting cameras can be sent to all devices at one time (broadcast). In the case of broadcast, the header should be hexadecimal 88H. When the terminator is FFH, it signifies the end of the packet.
Command List Responses for commands and inquiries Command execution cancel ● ACK message Returned by the FCB camera when it receives a command. No ACK message is returned for inquiries. To cancel a command which has already been sent, send the Cancel command as the next command. To cancel one of any two commands which have been sent, use the cancel message. ● Completion message Returned by the FCB camera when execution of commands or inquiries is completed.
Command List VISCA Device Setting Command Before starting control of the FCB camera, be sure to send the Address command and the IF_Clear command using the broadcast function. For VISCA network administration ● Address Sets an address of a peripheral device.
