1.3.1.1 PakBus Protocol/Direct RS-232 Connection
When using the PakBus protocol, the AVW200() instruction in CRBasic
supports an AVW200 connected to a datalogger via a cable attached to the
AVW200’s RS-232 port. You can run the datalogger AVW200() instruction in
either the pipeline or sequential mode. This instruction is contained in the
following datalogger operating systems:
• CR800std.06 or greater
• CR1000std.15 or greater
• CR3000std.08 or greater
Multiplexers can be controlled by either the AVW200 or the datalogger.
Read more! You can find Quick Start Guides in Section 3, AVW200()
instruction description in Section 6.1, and programming examples in
Section 7.
1.3.1.2 PakBus Protocol/Wireless Connection
An AVW206, AVW211, or AVW216 interface can transmit data to a
corresponding spread spectrum radio that is attached to the datalogger. The
AVW200() instruction in CRBasic supports these wireless interfaces. You can
run the AVW200() instruction in either the pipeline or sequential mode. This
instruction is contained in the following datalogger operating systems:
• CR800std.06 or greater
• CR1000std.15 or greater
• CR3000std.08 or greater
Multiplexers can be controlled by the wireless AVW200.

instruction description in Section 6.1, and a programming example in
Section 7.1.2.
1.3.1.3 PakBus Protocol/MD485 Communication
For situations where wireless communication is impractical, MD485 multidrop
modems may extend the distance between the AVW200 interfaces.
Multiplexers must be controlled by the AVW200.
Read more! Appendix I describes using MD485 modems with AVW200s.
1.3.1.4 SDI-12 Communication Mode
SDI-12 is the only option available for our CR5000, CR10X, and CR23X
dataloggers and non-Campbell Scientific dataloggers. Our CRBasic
dataloggers use the SDI12Recorder instruction and Edlog dataloggers (i.e.,
CR10X, CR23X) use Instruction 105. The SDI12Recorder instruction should
only be run in the sequential mode. When using SDI-12, multiplexers must be
controlled by the datalogger.
Read more! You can find a Quick Start Guide in Section 3.3.1,
SDI12Recorder instruction description in Section 6.2, and a programming
example in Section 7.5.
