Meter Control Unit: GLS-EM-MCU Introduction The GLS-EM-MCU is an Ethernet-based power metering control unit, designed to log overall electricity usage in real time. It measures and tracks actual energy consumption by attaching to the incoming electrical service and branch circuits. The GLS-EM-MCU also works in unison with the GLS-EM-CTI and GLS-EM-CT to provide more detailed data by tracking individual branch circuits in a home or office.
Real-time and Logged Data Inherent to the GLS-EM-MCU is the ability to provide both real-time and logged power usage data. Real-time data can be used on touch screens or lobby displays to show instantaneous usage.

Crestron Green Light Power Meter Control Unit Crestron GLS-EM-MCU If additional GLS-EM-MCU devices are to be added, repeat step 1 for each device. Each GLS-EM-MCU is assigned a different IP ID number as it is added. If necessary, double click a device to open the “Device Settings” window and change the IP ID, as shown in the following illustration.
GLS-EM-MCU Crestron Toolbox The USB port on the GLS-EM-MCU connects to the USB port on the PC via the included Type A to Type B USB cable: Use the Address Book in Crestron Toolbox to create an entry using the expected communication protocol (USB).
SIMPL Windows or Crestron Toolbox. Firmware Check the Crestron Web site to find the latest firmware. (New users may be required to register to obtain access to certain areas of the site, including the FTP site.) Upgrade GLS-EM-MCU firmware via Crestron Toolbox.
The current transformer calibration code is a 21 character string that is stored within the GLS-EM-MCU. The code is placed on the label of the GLS-EM-CT and must be entered into the current transformer calibration field of the GLS Energy Meter Configuration Tool.
