CHAPTER
4
COMMISSIONING
This chapter provides procedures to perform initial configuration and testing of a
newly installed Data Collector Unit (DCU).
The first power-up of the DCU requires that certain configuration settings be
confirmed and possibly edited. Use the following the instructions to connect your
laptop to the DCU’s technician port and issue commands.
The DCU design does not support public IP addresses. The installer is expected to
supply a private IP address. For cellular, this requires the use of Aclara’s Private
Network (APN), or the utility can set up their own private network with a cellular
provider. Aclara’s Private Network is a part of the Aclara Wireless Network
(AWN).
N
OTES A newly installed DCU may or may not be left in a powered state by the
installer. It is safer to work on the DCU with the AC power supply
disconnected. If the main board is replaced in a DCU, you may need to
complete this procedure once again.
Tools Required
• A laptop with HyperTerminal (or equivalent)
• Interface cable (Aclara #070-9975E)
Connect to the Main Board
1. Turn off AC power.
2. Open the DCU.
3. Verify that the serial port on the laptop is set to:
• 115200 BAUD
• Data Bits = 8
• Stop Bit = 1
• Parity = None
• Flow control = None
4. Remove the door switch connection at the P-box.
