1.5 CP -1: S ta n d a rd P ro c e s s o r Mo d u le
The CP-1 standard processor module provides all processing, I/O scan, logic, control and
communications functions required in any of the RTU configurations that may be adopted. This
module has two independent serial ports; one of which, port 2 (P2) may be software configured for
RS232C or RS485 circuit interfaces. Port 1 is fixed at RS232C.
In addition this module is available in two memory configurations. The standard configuration is 256K
of FLASH MEMORY for the storage of all operating code and selected system parameters, and 256K
of battery backed static RAM for all configuration and event storage data. This memory configuration
is ordered as CP-1-0. An optional extended memory configuration adds 512K of static RAM and is
ordered as CP-1-2. The extended memory configuration is only required in very large systems
employing many field RTUs which report back to a master RTU - all data being held in the master
RTU.
The RAM battery in earlier production units is enabled at shipping time by the factory. Later production
units allow the user to enable the battery by a link at the rear of the module - see figure below.

Two groups of four (4) LEDs show the status of ports 1 and 2. Each port has TXD, RXD, RTS and CD
LEDs in a vertical group. A green LED at the top of the face plate is ON when the module is operating
correctly. This module consumes power from the +5 VDC bus on the backplane. The module can be
installed in any I/O slot of a 6 or 12 slot backplane in a system. Up to two processor modules can be
installed in an RTU system. For example these two may reside anywhere in one, two, three or four
backplane systems.
