Real-Time Clock Battery
The CPE305 is shipped with a real time
clock (RTC) battery (IC690ACC001)
installed, with a pull-tabon the battery.
The pulltabshould be removed before
installing the CPE305.
There are no diagnosticsor indicators to
monitor RTC battery status. The RTC
battery has an estimated life of 5 years
and must be replaced every 5 years on a
regular maintenance schedule. If the RTC
battery fails, the CPU date andtime is
reset to 12:00 AM, 01-10-2000 at startup.
The CPU operates normally with a failed
or missing RTC battery; only the initial
CPU Time-of-day (TOD) clock information
will be incorrect.
Figure 1: Real-Time Clock
Battery
Ethernet Port
The embedded Ethernetinterface supports communications withthe
Machine Edition programming software usingthe proprietary SRTP
protocol. The CPE305 CPU provides two SRTP server connections.
The embedded Ethernetinterface has one RJ-45Ethernetport that
automatically senses the data rate (10 Mbps or 100 Mbps), duplex status
(half or full duplex), andcabling arrangement (straight through or
crossover)of the attached link.

6 PACSystems™ RX3i Central Processing Unit IC695CPE305 GFK-2934B
Serial Port
The CPE305 provides one RS-232serial interfaceto external devices. This
port can be used for firmware upgrades. The port is electrically isolated. For
serial port pinassignments anddetailson serial communications, refer to
the PACSystems RX3i CPUReference Manual, GFK-2222.
The RS-232 port does not supply the 5 VDC power offered by other RX3i
and Series 90-30 CPUs.Cable IC693CBL316 must be used for RS-232 serial
connections to the CPE305.
RemovableData StorageDevices
(RDSDs)
The CPE305 provides the ability to transfer applications to and from an
RDSD (USB compatible device, such as a memory stick, smart phone, digital
cameraor MP3 device). Once the datais copied to the RDSD, it can be
written to other RX3i CPE305 CPUs with no programmer software needed.
The RDSD interface requires auser-supplied flashmemory devicethat
complies with the USB 2.0 Specification.
The USB port must be enabled in the RX3i configuration in order to transfer
data between theCPU andthe RDSD. The CPE305 is shipped with theRDSD
(USB)port enabled. Completedetailsof the use of RDSDsare foundin the
PACSystems RX3i CPU ReferenceManual,GFK-2222.

7 PACSystems™ RX3i Central Processing Unit IC695CPE305 GFK-2934B
Energy Pack
The CPE305 preserves user memory using an Energy Pack without theneed
to periodically replace batteries. TheIC695ACC400 Energy Pack powers the
CPU long enough for the CPU to writeits user memory contents to the
CPU’s non-volatile storage during asystem power loss. Installation of the
Energy Pack is found below.

HardwareInstallation
Initial Checks
Upon receiving your RX3i equipment, carefully inspect all shipping
containers for damage. If any part of the systemis damaged, notify the
carrier immediately. The damagedshipping container should be saved as
evidence for inspection by the carrier.
Asthe consignee, it is your responsibility to register a claimwith the carrier
for damage incurred duringshipment. Emerson Automation Solutions will
fully cooperate with you, however, should such action be necessary.
After unpackingthe RX3i equipment, record all serial numbers.Serial
numbersare requiredif you shouldneedto contact Customer Care during
the warranty period. All shipping containersand all packingmaterial should
be saved should it be necessaryto transport or ship any part of the system.
Verify that all components of the system have been received and that they
agree with your order. If the system received does not agree with your
order, contact Customer Care.
Installation Location
Thisproduct is intended for use with the RX3i system. Its components are
considered open equipment (having live electrical parts that may be
accessible to users)andmust be installed in anultimate enclosure that is
manufactured to provide safety. As aminimum, the enclosureshall provide
a degree of protection against solidobjects as small as 12 mm(e.g. fingers).
This equates to aNEMA/UL Type 1 enclosure or an IEC60529 IP20 rating
providing at least a pollutiondegree 2 environment. Fordetailsabout

ModuleInstallation
For initial startupand configuration of the CPE305, complete thefollowing
steps. For full detailson CPE305 operation, refer to the PACSystems RX3i
and CPU Reference Manual, GFK-2222.
1. Remove the pull-tabfromthe Real Time Clock(RTC) battery, located on
the backof the CPE305.
2. Remove power fromthe RX3i
rack and install the CPE305. The
CPE305 may be installed in any
slot in the RX3i Main rack, except
the highest-numberedslot or
slot 0.
3. Holdingthe module firmly, align
the module with the correct slot
and connector, then swingthe
module down until the module’s
connector engages the
backplane’s backplane connector.
Visually inspect the module to be
sure it is properly seated.
4. Insert the two provided M3x5 mm
machine screws through the
module’s bottom bracket into
Figure 2: Module Installation

13 PACSystems™ RX3i Central Processing Unit IC695CPE305 GFK-2934B
threadedholes in the bottom of the backplate andscrew them several
turns usinga #1 Phillips screwdriver. Tighten to 0.7 N-m (6 in-lbs.).
5. Mount the Energy Pack onthe left side of the module inslot 0of the rack
(typically a power supply).
a. Engage the Energy Pack’s mounting hooks (at the top) on the frame of
the leftmost module.
b.Rotate the bottomof the EnergyPackinto place, engagingthe bottom
hooks. The latch will snap into place.
c.Connect cable IC695CBL001fromthe connectoronthe bottom of the
Energy Pack to the correspondingconnectoron the bottom of CPE305.
6. If required, connect theCPE305 to the Ethernet network.
7. Apply power to the rack.
Note: When the EnergyPackis powered up for the firsttime,or is
in a system that has been powered downlong enough to
completely discharge the Energy Pack, it may require a few
seconds for it tocharge to its operating level. The CPU’s
STATUS LED will blink green during this time.
ModuleInitial Startup
You Will Need:
•PACSystems RX3i CPU Firmware 8.00 or later.
•PAC Machine Edition™configuration and programming software,
version 8.0 or later.
•An IC693CBL316 serial or Ethernetcable for connectingthe
computer running the PAC MachineEdition programmer to the
RX3i CPU.

14 PACSystems™ RX3i Central Processing Unit IC695CPE305 GFK-2934B
Initial Configuration
1. Using PAC Machine Edition (PME) software, configure the CPE305 in
an RX3i target.
Note: If you intend to use the module’s embedded Ethernet
interface, you will probably need toassign it a new IP
address. To configure the embeddedEthernet interfacein
Machine Edition, expandthe CPU slot to displaythe
Ethernet daughterboard. The Settings tab for the
embedded Ethernet module contains IP Address, Subnet
Maskand GatewayIP Address (see the followingdiagram).
Consult your networkadministratorfor thepropervalues
for these parameters.
Figure 3: Configuration of the Ethernet Port on CPE305

15 PACSystems™ RX3i Central Processing Unit IC695CPE305 GFK-2934B
2. Go online with the target and download the configuration. You can
use one of the followingmethods for the initial connectionto the
CPE305:
a. Using an IC693CBL316 cable, connect to the module’s RJ-25 RS-232
serial port to the programmer computer. Thecomputer must be
equipped with an RS-232 serial port with a standard AT-style nine-pin
male D-connector.
b. Connect to the module’s
Ethernet port,usingthe
factory-loaded IP address,
192.168.0.100.
Note:Thisaddress is intended only
for initial connection in order to
complete the configuration.
After the initial configuration
download, must be changed
before connecting to the
Ethernet network.When you
store a hardware configuration
with a different IP address, the
temporary IP address islost; it is
not restored by a Clear
operation.
c. Through the Ethernetconnection of an ETM001 in the same rack with
a known IP address configuration.
