RS485 Termination
If the Camera unit is installed using a RS485 based control system, care needs to
taken to ensure the RS485 bus is terminated properly to prevent erratic operation.
The maximum length of cable that be used on one cable section in 1.2Km. There is a
maximum number of 32 devices that can reside on a cable section. All devices must
be un-terminated, with the exception of the last unit which must have its RS485
termination set to
ON
(S2-8 ON)
CAT5 cable or any cable that meets or exceeds the requirements for EIA RS485 may
be used for RS485 telemetry control
Figure 11
Keyboard Operation
Where possible, manufacturer key sequences have been implemented to make the
control of the camera unit as close as possible to the “normal” telemetry system
implemented by the OEM manufacturer, i.e. presets and tours can be programmed
and recalled in the same way from the manufacturers control system.
Where it has not been possible to implement all of the Camera unit features with a
manufacturer’s protocol, the extra features can be accessed through the camera unit
on-screen-menu.
Note
– OE manufacturers may update software or protocols in their keyboards
without prior warning, This may change the way in which the Camera unit behaves in
relation to keyboard operation. The manufacturer accepts no responsibility for such
changes in OE Manufacturer software/protocols.
