SerialInRecord
Reads incoming serial data on a COM port and stores the data in a destination
variable.
Syntax
SerialInRecord(COMPort, Dest, BeginWord, NBytes, EndWord,
NBytesReturned, LoadNAN)
SerialOpen
Sets up a datalogger port for communication with a non-PakBus device.
Syntax
SerialOpen(ComPort, BaudRate, Format, TXDelay, BufferSize)
SerialOut
Transmits a string over a datalogger communication port.
Syntax
SerialOut(ComPort, OutString, WaitString, NumberTries,
TimeOut)
SerialOutBlock
Send binary data out a communication port. Supports transparent serial talk-
through.
Syntax
SerialOutBlock(ComPort, Expression, NumberBytes)

PakBus is a proprietary networking communication protocol designed to optimize
communications between Campbell Scientific dataloggers and peripherals.
PakBus features auto-discovery and self-healing. Following is a list of CRBasic
instructions that control PakBus processes. Some PakBus instructions specify a
PakBus address (PakBusAddr) or a COM port (ComPort). PakBusAddr can be a
CRBasic variable. ComPort is a constant. ComPort arguments are as follows:
• ComRS232
• ComME
• Com310
• ComSDC7
• ComSDC8
• ComSDC10
