1) CS I/O Port Configuration
An SC105 may be activated either by the Modem Enable signal or by a
Synchronous Device (SDC) address (7, 8, or 9).
If PakBus Networking is being used, SDC address 7 or 8 should be
selected.
Addressed Print Device is a mode that allows output from the datalogger
when it executes the P96 instruction.
2) RS-232 Port Configuration
RS-232 baud rate, data bits, and parity are configured here, as well as the
RS-232 Auto Power Down (APD) Mode. The APD mode should be left
enabled, unless the attached RS-232 device requires power from the
RS-232 lines.
The DTR and RTS Mode setting allows control over how these two lines
behave.
DTR is on pin 4 of the RS-232 connector; RTS is on pin 7.
