1Introduction
This Document details how to configure the RL4512 CO2and Temperature Sensor Unit from
Ellab Monitoring Solutions Ltd for use in conjunction with the EMS application.
The RL4512 Unit is a Dual Channel Transmitter with channels for CO2and Temperature data
inputs from their respective sensors/probes.
The RL4512 Unit also has an on-board Data Logging facility. This facility can provide a data
backup capability in the event of a transmission or power failure or other interruption to the
flow of data from the Unit to EMS.
•Data is transmitted/uploaded to EMS from the Unit at defined Transmission Intervals,
either directly or via an SR2 Controller.
The current CO2and Temperature values, battery voltage and, optionally, the Alarm Status are
also displayed on the Unit’s LCD screen.
1.1 Pre-requisites
You will need the following to enable communication between EMS and the RL4512 Unit:
•Y055 USB lead.
•EMS application installed on a PC/Server.
•EMS Remote Management Tools
If the RL4512 Unit can be physically connected to the PC/Server with EMS installed or if
EMS is installed on a Virtual Machine (VM) or a Remote Server.
•Upgrade Disk
Installations running EMS Version 1.7.0 or lower must run this disk and follow the
instructions in the ReadMe.txt file before adding the Sensor Unit to EMS.
