Modular Radio Telemetry System
1.5
Connecting output Modules to the 210 Receiver
200 Series
A range of ‘200’ series output modules are available which can be plugged into the 210 Receiver via the four
IDC header boxes on the receiver. The selection of output module will be dependant on the application. Please
see DS200S-1 for a summary the available modules.
1.6
Connecting an Antenna
The 210Rx has a 200mm flying lead cable (50ohm) with a panel mount BNC socket provided to mount on an
enclosure. This cable may be extended however please note that typically there is a 50% range reduction
with every 3metres of coax cable used!
For increasing range performance a +3dB gain antenna is available. This is supplied with wall mounting
bracket and 2metres of coax cable, it plugs in directly to the 210Rx BNC connector.
1.7
Range
The antenna choice and position directly controls the system range. Keep it clear of other metal in the system.
The best position by far, is protruding from the top of the product. This is often not desirable for practical or
ergonomic reasons and thus a compromise may be needed. If an internal antenna must be used then try to
keep it away from other metal items, and in particular large ones like transformers, batteries and PCB tracks
and earth planes.
Note that the space around the antenna is as important as the antenna itself. All radio systems are dependant
on a radio signal being received through airspace.
The range quoted is the optimal in direct line of sight without obstacles and in good atmospheric conditions.
Range is affected by many things, for example local environmental conditions, atmospheric conditions,
interference from other radio transmitters. For evaluating the local environment please see our RF Meter
(DS006)
In very worse case applications the range quoted may be reduced to 30% of the optimal range stated.
1.8
Signal integrity
In systems where many encoders are in close proximity there may be occasions when, due to signal overlay
between encoders, it is difficult or impossible to guarantee system integrity. In such circumstances it is the
responsibility of the installer to ensure that the system performance is adequate for the purposes of the
installation.
