unregulated 12 volts. The output is limited to 600 mA current. A control port is used to operate the switch. Connect a wire from the control port to the switched 12 volt control port. When the port is set high, the 12 volts is turned on; when the port is low, the switched 12 volts is off (Section 8.12). OV1.2 CONNECTING POWER TO THE CR10X The CR10X can be powered by any 12VDC source. The green power connector is a plug in connector that allows the power supply to be easily disconnected without unscrewing the terminals. The Wiring Panel power connection is reverse polarity protected. See Section 14 for details on power supply connections. CAUTION: The metal surfaces of the CR10X Wiring Panel, and CR10KD Keyboard Display are at the same potential as power ground. To avoid shorting 12 volts to ground, connect the 12 volt lead first, then connect the ground lead. When primary power falls below 9.6 VDC for one millisecond, the CR10X stops executing its programs. The Low Voltage Counter (∗B window 9) is incremented by one each time the primary power falls below 9.6 VDC and E10 is displayed on the CR10KD. A double dash (--) in the 9th window of the ∗B mode indicates that the CR10X is currently in a low primary power mode. (Section 1.6) The datalogger program and stored data remain in memory, and the clock continues to keep time when power is disconnected. The clock and SRAM are powered by an internal lithium battery. OV2. MEMORY AND PROGRAMMING CONCEPTS OV2.1 INTERNAL MEMORY The standard CR10X has 128 K of Flash Electrically Erasable Programmable Read Only Memory (EEPROM) and 128 K Static Random Access Memory (SRAM). The Flash EEPROM stores the operating system and user programs. RAM is used for data and running the program. CR10X OVERVIEW Data Storage can be expanded with an optional Flash EEPROM (Figure OV2.1-1). The use of the Input, Intermediate, and Final Storage in the measurement and data processing sequence is shown in Figure OV2.1-2. The five areas of SRAM are: 1. System Memory - used for overhead tasks such as compiling programs, transferring data, etc. The user cannot access this memory. 2. Program Memory - available for user entered programs. 3. Input Storage - Input Storage holds the results of measurements or calculations. The ∗6 Mode is used to view Input Storage locations for checking current sensor readings or calculated values. Input Storage defaults to 28 locations. Additional locations can be assigned using the ∗A Mode. 4. Intermediate Storage - Certain Processing Instructions and most of the Output Processing Instructions maintain intermediate results in Intermediate Storage. Intermediate storage is automatically accessed by the instructions and cannot be accessed by the user. The default allocation is 64 locations. The number of locations can be changed using the ∗A Mode. 5. Final Storage - Final processed values are stored here for transfer to printer, solid state Storage Module or for retrieval via telecommunication links. Values are stored in Final Storage only by the Output Processing Instructions and only when the Output Flag is set in the user's program. Approximately 62,000 locations are allocated to Final Storage on power up. This number is reduced if Input or Intermediate Storage is increased. While the total size of these three areas remains constant, memory may be reallocated between the areas to accommodate different measurement and processing needs (∗A Mode, Section 1.5). OV-5

CR10X OVERVIEW

OV-5

unregulated 12 volts.

The output is limited to

600 mA current.

A control port is used to operate the switch.

Connect a wire from the control port to the

switched 12 volt control port.

When the port is

set high, the 12 volts is turned on; when the port

is low, the switched 12 volts is off (Section 8.12).

OV1.2

CONNECTING POWER TO THE CR10X

The CR10X can be powered by any 12VDC

source.

The green power connector is a plug in

connector that allows the power supply to be

easily disconnected without unscrewing the

terminals.

The Wiring Panel power connection

is reverse polarity protected.

See Section 14 for

details on power supply connections.

CAUTION

The metal surfaces of the

CR10X Wiring Panel, and CR10KD

Keyboard Display are at the same potential

as power ground.

To avoid shorting 12

volts to ground, connect the 12 volt lead

first, then connect the ground lead.

When primary power falls below 9.6 VDC for

one millisecond, the CR10X stops executing its

programs.

The Low Voltage Counter (

∗

window 9) is incremented by one each time the

primary power falls below 9.6 VDC and E10 is

displayed on the CR10KD.

A double dash (--) in

the 9th window of the

∗

B mode indicates that

the CR10X is currently in a low primary power

mode. (Section 1.6)

The datalogger program and stored data remain

in memory, and the clock continues to keep

time when power is disconnected.

The clock

and SRAM are powered by an internal lithium

battery.

MEMORY AND PROGRAMMING

CONCEPTS

OV2.1

INTERNAL MEMORY

The standard CR10X has 128 K of Flash

Electrically Erasable Programmable Read Only

Memory (EEPROM) and 128 K Static Random

Access Memory (SRAM).

The Flash EEPROM

stores the operating system and user programs.

RAM is used for data and running the program.

Data Storage can be expanded with an optional

Flash EEPROM (Figure OV2.1-1).

The use of

the Input, Intermediate, and Final Storage in the

measurement and data processing sequence is

shown in Figure OV2.1-2.

The five areas of

SRAM are:

System Memory

- used for overhead tasks

such as compiling programs, transferring

data, etc.

The user cannot access this

memory.

Program Memory

- available for user

entered programs.

Input Storage

- Input Storage holds the

results of measurements or calculations.

The

∗

6 Mode is used to view Input Storage

locations for checking current sensor

readings or calculated values.

Input

Storage defaults to 28 locations.

Additional

locations can be assigned using the

∗

Mode.

Intermediate Storage

- Certain Processing

Instructions and most of the Output

Processing Instructions maintain

intermediate results in Intermediate

Storage.

Intermediate storage is

automatically accessed by the instructions

and cannot be accessed by the user.

The

default allocation is 64 locations.

The

number of locations can be changed using

the

∗

A Mode.

Final Storage

- Final processed values are

stored here for transfer to printer, solid state

Storage Module or for retrieval via

telecommunication links.

Values are stored

in Final Storage only by the Output

Processing Instructions and only when the

Output Flag is set in the user’s program.

Approximately 62,000 locations are

allocated to Final Storage on power up.

This number is reduced if Input or

Intermediate Storage is increased.

While the total size of these three areas

remains constant, memory may be reallocated

between the areas to accommodate different

measurement and processing needs (

∗

A Mode,

Section 1.5).
