R450™MIU Wall and Pit Installation and Maintenance Guide 1
Chapter 1: Product Description
Overview
This section provides a general description of the Neptune R450™ Meter Interface Unit
(R450 MIU or MIU). The R450 MIU is a compact electronic device that collects meter
reading data from an encoder register. It then transmits the data for billing. The R450
MIU is designed for use with multiple types of approved encoder registers:
lNeptune ARB®III, IV, and V
lProRead™, ProCoder™, and E-CODER®
lSensus (Invensys) ECR®II and ECR®III
Before installing the R450 MIU, the encoder register must be wired correctly and
programmed to work with the MIU.
lWhen using a ProRead encoder register (Rev. E or earlier), the ProRead register
must be programmed for three-wire mode.
lIf using a new ProRead register (Rev. F or later), AutoDetect can recognize it, and it
does not need to be programmed.
lIf using an existing register, make sure all three wires are connected, and it is
programmed in three-wire mode.
Figure 1 – R450™ Wall and Pit MIU

To ensure that the ProRead™ register is programmed for three-wire mode, use the
ProRead programmer and its Radio Frequency (RF) / MIU 6, 8, or 10 ID Transport
Driver Interface (TDI) format. Do this using the ProRead receptacle before removing the
receptacle or three bare wires.
The R450 MIU is easy to install and requires a Federal Communications Commission
(FCC) license to operate. For information on obtaining an FCC license, refer to “FCC
Licensing,” in the ARB®N_SIGHT™ FixedBase New Customer Guide.
R450™ MIU Programming
You can upgrade and configure the MIU. At the factory, serial numbers are
programmed into the MIU. Each MIU has two unique serial numbers / identification
numbers (two IDs for compound units). Even numbers are for the single registers and
odd numbers are for a two-networked register unit. Custom serial numbers are not
available.
RF Protocol Error Detection
The RF protocol is comprised of a header, data packet, and an error detection
mechanism that reduces the erroneous data.
Low Battery RF Emissions
The MIU does not produce out-of-band emissions under low battery conditions.
