When using a computer/terminal to communicate
with the CR510 (Telecommunications remote
keyboard state) there are some keys available in
addition to those found on the CR10KD. Table
OV3.1-3 lists these keys.

OV3.2 USING COMPUTER WITH DATALOGGER
SUPPORT SOFTWARE
Direct datalogger communication programs in
the datalogger support software provide menu
selection of tools to perform the datalogger
functions (e.g., set clock, send program,
monitor measurements, and collect data). The
user also has the option of directly entering
keyboard commands via a built-in terminal
emulator (Section OV3.3).
When using the support software, the
computer's baud rate, port, and modem types
are specified and stored in a file for future use.
The simplest and most common interface is the
SC32A Optically Isolated RS232 Interface. The
SC32A converts and optically isolates the
voltages passing between the CR510 and the
external terminal device.
The SC12 Two Peripheral cable which comes
with the SC32A is used to connect the serial I/O
port of the CR510 to the 9 pin port of the SC32A
labeled "Datalogger". Connect the
"Terminal/Printer" port of the SC32A to the
serial port of the computer with a straight 25 pin
cable or, if the computer has a 9 pin serial port,
a standard 9 to 25 pin adapter cable.
OV3.3 ASCII TERMINAL OR COMPUTER WITH
TERMINAL EMULATOR
Devices which can be used to communicate
with the CR510 include standard ASCII
terminals and computers programmed to
function as a terminal emulator. See Section
6.7 for details.
To communicate with any device other than the
CR10KD, the CR510 enters its Telecom-
munications Mode and responds only to valid
telecommunications commands. Within the
Telecommunications Mode, there are 2 "states";
the Telecommunications Command state and the
Remote Keyboard state. Communication is
established in the Telecommunications command
state. One of the commands is to enter the
Remote Keyboard state (Section 5).
The Remote Keyboard state allows the
keyboard of the computer/terminal to act like
the CR10KD keyboard. Various datalogger
modes may be entered, including the mode in
which programs may be keyed in to the CR510
from the computer/terminal.
OV4. PROGRAMMING THE CR510
A datalogger program is created on a computer
using EDLOG or one of the programming aids
such as Short Cut. A program can also be
entered directly into the datalogger. Section
OV4.3 describes options for loading the
program into the CR510.
