Real-Time Clock Battery
The CPE302 is shipped with a real time
clock (RTC) battery (IC690ACC001)
installed, with a pull-tab on the battery.
The pull tab should be removed before
installing the CPE302.
There are no diagnostics or 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 and time 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.

Ethernet Port
The embedded Ethernet interface supports communications with the
Machine Edition programming software using the proprietary SRTP
protocol. The CPE302 CPU provides two SRTP server connections.
The embedded Ethernet interface has one RJ-45 Ethernet port that
automatically senses the data rate (10 Mbps or 100 Mbps), duplex status
(half or full duplex), and cabling arrangement (straight through or
crossover) of the attached link.
