telemetry.
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 1-2-1 converter can be adjusted to select banks of cameras as follows:
When the 1-2-1 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.
i). Timing to the dome is critical, due to the nature of the dome protocol (half duplex command and
response commands). The dome will ignore any command sent before it has finished executing the
previous command; for example, a goto preset command sent whilst the dome is searching for another
preset, (e.g. multiple alarm occurrences in quick succession).
ii) Supported manual PTZ with manual focus which reverts back to auto focus on a pan/tilt or zoom.
iii) 64 preset positions are supported
iv) The AUTOPAN key is used to start patrol 2.
v) 2 preset patrols are provided and the preset positions in each patrol are programmable. Patrol 1 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. 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 a 10 second dwell at each
position. Programming is similar to 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.
vi) LEDS, LD2 flashes when commands are received for domes that lie outside of the 31 camera range set
by SW2, SW4/7 and SW4/8.
IMPORTANT: THE DOME WILL IGNORE ALL COMMANDS SENT FROM THE 1-2-1 CONVERTER
WHEN IT IS MOVING TO A PRESET POSITION UNTIL THE PRESET POSITION HAS BEEN REACHED.
THIS RELATES TO MANUAL PRESET OR DURING A PATROL.
