1.5 Connecting output Modules to the 210 Receiver

The receiver has 16 outputs. These are connected to the relay output module via a ribbon cable.

The outputs are presented according to the following table.

1.6 Relay Outputs

Each output relay provides an isolated switch. Connections are Common (COM), Normally Open (NO),

Normally Closed (NC).

2 Antenna and Range

2.1 Antenna

The system includes an antenna. It is situated within the enclosure (to save penetrating the enclosure)

If the range is inadequate then it may be necessary to mount the antenna protruding from the enclosure. This

may be easily fitted using the provided panel mount BNC socket. The antenna 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 BNC connector.

2.2 Range

The antenna choice and position directly controls the system range. Keep it clear of other metal in the system.

The best position 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.

2.3 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.
