LAYOUT OF THE BBV Tx1000 KEYPAD Connections Having mounted the base unit on the wall or in a rack, continue as follows: 1. Connect the keypad to 9-pin d socket marked "Keypad 1". 2. Connect a BNC cable from output M1 to the keypad, and connect the other keypad connection to Monitor 1. Terminate the cable at the monitor. 3. If the keypad is remotely sited from the base unit, connect the plug-mounted power supply to the keypad via the 2.1mm power connector. 4.
Camera Selection A camera may be selected onto the controlled monitor by pressing the relevant numbered key. Monitor Selection The monitor key has a red LED which is lit when the keypad is controlling the second monitor output. Pressing the monitor key toggles between the main monitor and the second monitor. Sequence Activation Pressing the sequence key will start the sequence on the MAIN monitor. The on-screen display changes from CAM XX to SEQ XX to indicate that the sequence is running.
KEYPAD FUNCTIONS Pan and Tilt Action: Press the relevant direction arrow(s) Lens Action There are six lens-function switches on the BBV Tx400 keypad. These are Iris Open, Iris Close, Focus Near, Focus Far, Zoom In and Zoom Out. Press and hold the relevant key until the desired picture is obtained. Note: If the key is pressed and held for longer than one second, High Speed Lens Action is activated. Inching is achieved by repeated quick presses of the key.
SELF TEST To activate the self test feature for any particular camera reciever, first select that receiver, then press the Program button and select Menu Option 2. The screen text will clear and Self Test will be activated . See the Rx Series Telemetry Receiver Installation Handbook for more details. ------------ IRIS LEVEL PROGRAM To preset the aperture of the iris, press Iris Open or Iris Close until the desired level is reached, then press Program and Option 3.
The remainder of this manual refers to features found only on the Rx400P receiver. PRESETS To select a pre-programmed preset, press the Preset key. On the screen, "Preset" will appear. While holding down the Preset key, select the desired preset number. ------------ To programme a preset, first position the camera using the Up/Down and Left/Right arrows. Then set Zoom and Focus. When satisfied with the position and the quality of the picture, press Program and select Option 1.
PATROL SETTINGS There are two patrol commands that can be started by the BBV Tx1000. They are activated by pressing the Patrol key and either Key 1 or Key 2. All other keys are ignored. Their function is to enable a string of presets to be selected in turn, switching between presets after a fixed period of time (nominally 30 seconds). Note: Once the nominal time period of 30 seconds has been altered, it cannot revert back.
To Programme a Time Period for a Patrol First, determine the time delay required from the table below: key 1 key 2 key 3 key 4 key 5 key 6 key 7 key 8 random, 0 to 100 seconds 12 seconds 24 seconds 36 seconds 48 seconds 60 seconds 72 seconds 84 seconds key 9 key 10 key 11 key 12 key 13 key 14 key 15 key 16 96 seconds 108 seconds 120 seconds 132 seconds 144 seconds 156 seconds 168 seconds 180 seconds SPARE OUTPUTS There are four spare outputs, which are momentary-action, for use as relay drivers.
Tx1000 Series Alarm Input Option WARNING: Only qualified persons should install this apparatus. It contains no user-serviceable parts. Alarm Inputs Alarms activate on opening of contacts. Connect each alarm pair to a volts free contact. 1 2 3 4 5 6 7 8 9 1 0 1 1 1 2 1 3 1 4 1 5 1 6 Normaly closed, opening for alarm.
ALARM CONTACTS Installer fitted keyswitch to control alarm package The alarm package may be enabled/disabled via a keyswitch fitted across alarm contacts pins 1 and 2. When the switch is closed the alarm package is disabled, opening the switch and the alarm package is active. This may be used to control the alarm package, i.e. enabled at night when the building is empty etc. Note that cutting the switch cable will activate the alarm package.
TWISTED PAIR OPTION The TWISTED PAIR option sends telemetry signals from the transmitter to the receiver. A video cable connection is still required. The normal reason for using a twisted pair option is to connect to a non-cable transmission system, fibre, microwave etc. The twisted pair output option provides a 20mA compatible output. 1200 baud 8 data bits 1 stop bit.
Additional information It is strongly recommended that this equipment is pre-built in the installer's workshop in advance, to ensure problem-free installation at the customer's premises. 1. The software version number is displayed for approx 2 seconds on first power up eg "VF" 2. The keypads should not be connected or disconnected from a "live" working unit, as this may damage the RS232 components. 3. A new menu item "15" now appears on pressing the program key.
