MDR2400 and MDR5800 User Manual 2 2.1 TECHNICAL DESCRIPTION System Overview An MDR digital radio link (DRL) consists of a pair of MDR radio stations. MDR5800 OR MDR2400 OU MDR IDU User Data MDR5800 OR MDR2400 OU MDR IDU User Data The MDR radio stations consists of two main parts: • An Outdoor Unit operating in the 2.4GHz or 5.8 GHz ISM frequency bands. The Outdoor Unit provides the radio transceiver functionality by accepting radio link data from the Indoor Unit and converting it to the 2.
MDR2400 and MDR5800 User Manual The MDR5800 Outdoor Units operate in the 5.725 GHz to 5.850 GHz ISM frequency band. The MDR5800 has predefined frequency channel plans (termed A, B, C and D). The MDR2400 Outdoor Units operate in the 2.400 GHz to 2.4835 GHz ISM frequency band. The MDR2400 has predefined frequency channel plans (termed A, B and D). 2.2.1.
MDR2400 and MDR5800 User Manual 2.2.1.3 MDR2400 FCC Compliant Frequency Channels for the U.S. only In countries where FCC compliance is required, only the following frequencies may be used: Low band outdoor unit – 2412MHz to 2426MHz, High band outdoor unit – 2458MHz. Use frequency plan D (variable frequency) to set the outdoor unit. LOW BAND TRANSMIT DL 2412 DL 2426 HIGH BAND TRANSMIT DH 2458 Frequency (MHz) Figure 3. MDR2400 FCC Compliant Frequency Channels for the U.S.
MDR2400 and MDR5800 User Manual Frequency Channel Plan D Frequency plan D allows independent control of transmit and receive frequencies. This enables a very flexible frequency plan and can be used to overcome interference in the 2.4GHz and 5.8 GHz ISM bands. The frequencies that can be used in the lower or upper sub-bands can be selected in 1 MHz increments. Performance degradation can be expected when operating using channel plan D mode and the chosen frequencies are close to the sub-band edges i.e.

MDR2400 and MDR5800 User Manual 10 APPENDIX B: MANAGEMENT OF THE MDR2400 AND MDR5800 All management of the MDR product is implemented using SNMP (Simple Network Management Protocol), an open standard. The MDR product can be managed by: 1. Standard SNMP managers such as HP OpenView or SNMPc i.e. there is Open Network Management compatibility. 2.
MDR2400 and MDR5800 User Manual There are three principle requirements to use SNMP with the MDR Radio Stations. 1. A Management Station that runs a SNMP Management Software package that is installed on a networked or stand-alone PC that can be connected to an Indoor Unit either using a serial connection or an Ethernet connection. From the Management station, the agents within the MDR Indoor Units can be configured or polled for information. 2.
