RS485 Star Card Manual V14 4Feb04.doc Page 22/29
CBC SMD20, STAR MD2000, SANYO VCC9200P from BBV telemetry.
Connect dome DATA+ to Converter TRA and dome DATA- to Converter TRB.
Set the dome address using the DIL switch to match the number of the camera input of
the TX1500. Ensure that the dome at the end of a daisy chained RS485 run has the
RS485 terminated and the intermediate domes have the RS485 de-terminated.
This type of dome can be addressed from 1 – 31. To allow use of more that 31 domes on
a Tx1500 system the converter can be adjusted to select banks of cameras as follows:
Camera Range SW2/7 SW2/8
1 – 31 OFF OFF (This is the default setting)
32 – 62 ON OFF
63 – 93 OFF ON
94 – 124 ON ON
When the converter is set for camera range 32 – 62, the dome connected into video
input 32 must have the address set for 1 and video input 33 must have the address set to
2 etc up to video input 62 with the address set to 31. Multiple Starcard/Converter must be
used when controlling more that 31 cameras with SW2/7 and SW/8 set appropriately.
i) Because of the nature of the dome protocol which uses half duplex command and
response commands timing to the dome is critical. If a command is sent to the dome
before it has finished executing the previous command, the new command is ignore!!!
Even if this is another goto preset command whilst the dome is searching for another
preset, say if get multiple alarm occurrences in quick succession. This would appear that
the controller hasn't sent the command to the dome... not the case.
ii) The converter is limited to control ONE dome at a time because of this timing. A
lockout period prevents other cameras on a single starcard from being controlled until 5
seconds after the last command has been sent to the current camera.
THIS INCLUDES PRESET COMMANDS...
iii) Supported manual ptz with manual focus which reverts back to auto focus on a pan/tilt
or zoom.
iv) 64 preset positions are supported
v) The AUTOPAN key is used to start patrol 2.
vi) 2 preset patrols are provided and the preset positions in each patrol are
programmable. Patrol 1 is has a fixed full speed movement to each preset and a dwell of
10 seconds. To define patrol 1, first PROGRAM 65 PRESET, followed by GOTO preset
for each of the presets to be patrolled. Up to 64 presets can be programmed. Obviously
each preset position must be programmed prior to defining the patrol. To end the
definition PROGRAM 66 PRESET.
Patrol 2 has a fixed slow speed movement between preset positions and again a 10
second dwell at each position. Programming follows the same idea as patrol 1.
PROGRAM 67 PRESET to start definition, goto preset ... followed by PROGRAM 68
PRESET to end the definition. Patrol 2 can also be started by pressing the AUTOPAN
key.
vii) LEDS, LD3 flashes when commands are received for domes that lie outside of the 31
camera range set by SW2/7 and SW2/8.
IMPORTANT... IF THE DOME IS MOVING TO A PRESET POSITION THE DOME WILL
IGNORE ALL COMMANDS THAT ARE SENT FROM THE CONVERTER UNTIL THE
PRESET POSITION HAS BEEN REACHED. THIS RELATES TO MANUAL PRESET OR
DURING A PATROL.
