MDR / ORION 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 MDR 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.
Table 12 indicates the compatibility between different indoor and outdoor unit
types. The IU firmware types required to provide the compatibility between
different hardware types are listed in.
NOTE Different indoor unit firmware versions may be required to provide
compatibility between different indoor and outdoor unit types.

Older versions (up to version 3.08) of the firmware are only suitable for MDR
indoor units and are identified by the following filename:
idu_x_xx.cvf, where the x_xx is the numeric version number.
Newer firmware versions (version 4 upwards) are identified by the following
filename:
abcddeeefghI_x_xx.cvf, where x_xx is the numeric version number of the
firmware. The other fields in the name has the following meaning:
a: M or O = Indoor Unit PCB (MDR or Orion)
b: C=100 X=10 Ethernet to OU (or - if both are supported)
c: 2=v2 framing 3=v3 framing structure (3 is programmable, 2 is used on
MDR)
dd: tt = 04=4 tribs 08=8 tribs E3, T3, etc
eee: 2.4 5.8 if it's specifically limited, not in name if not used
f: T or E for T1/E1 if it's specifically limited, not in name if not used
ghi: Reserved, not in number if not used
