458MHz PZT Telemetry System
X7306
This connection method provides a 20mA current loop link suitable for use with Baxall-type
equipment.
To ensure correct operation:
• Set the jumper on the transmitter PCB to the 20mA BAXEL setting.
• Set the jumpers on the receiver PCB to the BAXEL and 20mA settings.
• Connect 12VDC 500mA supplies to the Power Input terminals on both the transmitter and
receiver PCBs.
Mounting the Units
The Telemetry transmitter and receiver units are provided with unidirectional whip antennae. To
obtain optimum signal strength, the transmitter and receiver antennae should be unrestricted. For
instance, if the box is mounted onto a wall, where possible, the antenna should stand clear of the
wall.
• When the Telemetry system is being used in conjunction with the Microvision wireless video link
(or another similar system), the Telemetry unit should be placed no closer than 1 metre from the
Microvision antenna.
• The Telemetry unit should never be placed in the line of sight between the Microvision antennae.
• If the Telemetry and Microvision systems must be placed in close proximity, place the Telemetry
units above the Microvision boxes.
IMPORTANT: The telemetry transmitter should never be powered without the correct antennae
being fitted.
