Teledyne API Model 200AU NOX Analyzer Instruction Manual, 02293, Rev. F

Security Feature

The RS-232 port is often connected to a public telephone line which could compromise instrument security. If the LOGON feature is implemented, the port has the following attributes:

1.A password is required before the port will operate.

2.If the port is inactive for 1 hour, it will automatically LOGOFF.

3.Repeat attempts at logging on with incorrect passwords will cause subsequent logins (even with the correct password) to be disabled for 1 hour.

4.If not logged on, the only command that is active is the '?'.

5.The following messages will be given at logon.

LOG ON SUCCESSFUL

Correct password given

LOG ON FAILED

Password not given or incorrect

LOG OFF SUCCESSFUL

Logged off

The RS-232 LOGON feature must be enabled from the front panel by setting bit 4 of the RS232_MODE variable in the VARS menu, see Table 9-5. Once the feature is enabled, to logon type:

LOGON 940331

940331 is the default password. The password can be changed to any number from 0 to 999999 by the variable RS232_PASS. To change the password enter the command

V RS232_PASS=NNNNNN

which sets the password to the value NNNNNN.

Protocol of Port Communication

The RS-232 interface has two protocols of communication, because if the port is attached to a computer it needs to have different characteristics than if used interactively. Consequently, there are two primary styles of operation: terminal mode and computer mode.

When an operator is communicating with the analyzer via a terminal, the analyzer should be placed into TERMINAL MODE, which echoes keystrokes, allows editing of the command line using the backspace and escape keys, and allows recall of the previous command. When a host computer or data logger is connected to the analyzer, it should be placed into COMPUTER MODE, which does not echo characters received or allow the special editing keys. See Table 5-11 for relevant commands.
