M120 Module User Guide Introduction The M120 is a battery operated module designed for automated gas meter reading. The M120 is capable of recording gas consumption data from residential gas meters. It has a 2-way radio that is compatible with electric meters, routers, and mesh extenders for relaying sensor data to the utility. Federal Communication Commission (FCC) Compliance Notice This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: 1. This device may not cause harmful interference, and 2. This device must accept any interference received, including interference that may cause undesired operation. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: 1. Reorient or relocate the receiving antenna. 2. Increase the separation between the equipment and receiver. 3. Consult Landis+Gyr or an experienced radio technician for help. U WARNING: Changes or modifications to this device not expressly approved by Landis+Gyr will void the equipment warranty. User Guide 98-1718 Rev AA 3

Landis+Gyr M120 Module User Guide • 9.6 kbps: -112 dBm • 19.2 kbps: -110 dBm • 38.4 kbps: -108 dBm • 115.2 kbps: -101 dBm • Max Input Power, No Damage: 10 dBm Functional Description The M120 is a wireless battery endpoint for the application of automatic gas meter reading. The primary function of the module is to record pulses that represent measurement of gas consumption, and then deliver the data to the utility for processing. The block diagram below demonstrates this operation. Figure 1. Operation Block Diagram The module is designed to record pulses from a Form-C type pulse initiator. The pulse initiator is a sensor board that measures gas volume flow and relays the measurement to the M120 in the form of electrical pulses. The radio has two operating modes, frequency hopping and single channel. The frequency hopping mode is the normal operating mode for network communication. The single channel mode is a low power mode, and is primarily used for field diagnostic purposes. User Guide 98-1718 Rev AA 5
