3.1 Set-up Menu Selections

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, 9, 10, or 11).

If PakBus Networking is being used, SDC address 7, 8, 10, or 11 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.

‘PC/PDA mode’: DTR and RTS are both driven to 5 V.

‘Modem mode’: DTR will be driven to +5 V when the CS I/O interface

is active for Modem Enable, SDC Address 9, and
Addressed Print Device configurations. When the
CS I/O is inactive, DTR will be 0 V.
