INDOOR UNIT FIRMWARE UPGRADE NOTICE
MDR Version 2 hardware Indoor Units are identified as having 200+ serial numbers, Outdoor Units
have 250+ serial numbers.
If upgrading Indoor Units to use V2.02+ IU firmware, upgrade the IU firmware on BOTH sides of
the RF Link.
Note that firmware upgrades of Version 1 Indoor Unit hardware do not require setting up of the
PCB Issue in the MIB i.e. mdrmteIndoorUnitPCBrevision element. Upgrade to IU firmware Version
2+ of Version 1 hardware will NOT give improved RSSI functionality. This is only achieved with
Version 2 hardware or modified version 1 hardware.
As a standard setting for mdrmteIndoorUnitPCBrevision, use MIB selection Issue_2. HOWEVER,
if an appropriate Indoor PCB modification (made at the factory) has been made to allow Full
Duplex Ethernet operation, the Issue_2_Mod_A selection option in the MIB MUST be used.
