Supported protocols Bosch/Philips
For RS-485 and BiPhase are implemented 4 different protocols, which are defined for the output data.
Input protocol is detected automatically.
Fixed-Start-Stop (optocode 0x02) – The protocol sends START and STOP commands, with no
information about the speed of movement. Commands used in old type PTZ telemetry receivers and
heads.
Fixed-Repetive (optocode 0x04) – The protocol sending only the START command at intervals up to
every 50ms (20Hz), with no information about the speed of rotation. Commands used in old type PTZ
telemetry receivers and heads. This protocol does not support Iris Close and Iris Open commands.
Variable-Start-Stop (optocode 0x05) - The protocol sending START and STOP commands, including
information about the speed of rotation. Commands used in new type PTZ telemetry receivers and
speed-dome cameras. Often also used in cameras from other manufacturers with support of Bosch or
Philips code.
Variable-Start-Stop (optocode 0x08) - The protocol sending only the START command at intervals up
to every 50ms (20Hz), with information about the speed of movement. Mainly used in cameras using the
Speed-Dome Bosch. It is not recommended to radio transmission and LAN network using the LAN to
RS-485 converters.
Commands (optocode 0x07) – Special commands: Presets, Auxilary ON/OFF commands. Compatible
with all systems.
