8.3.7 Memory Q & A
Q: Can a user create a program too large to fit on the CPU: drive (>100k) and
have it run from the CRD: drive (memory card)?
A: The program does not run from the memory card. However, a very large
program (too large to fit on the CPU: drive) can be compiled into CR1000 main
memory from the card if the binary form of the compiled program does not
exceed the available main memory
(p. 370).

Telecommunications, in the context of CR1000 operation, is the movement of
information between the CR1000 and another computing device, usually a PC.
The information can be data, program, files, or control commands.
Telecommunication systems require three principal components: hardware, carrier
signal, and protocol. For example, a common way to communicate with the
CR1000 is with PC200W software by way of a PC COM port. In this example,
hardware are the PC COM port, CR1000 RS-232 port, and a serial cable. The
carrier signal is RS-232, and the protocol is PakBus
®
. Of these three, you will
most often be required to choose only the hardware, since carrier signal and
protocol are transparent in most applications.
Systems usually require a single type of hardware and carrier signal. Some
applications, however, require hybrid systems of two or more hardware and signal
carriers.
Contact a Campbell Scientific application engineer for assistance in configuring a
telecommunication system.
Synopses of software to support telecommunication devices and protocols are
found in the appendix Support Software
(p. 654). Of special note is Network
Planner
, a LoggerNet client designed to simplify the configuration of PakBus
telecommunication networks.
