3.2 Configuration

730 Sample Changer, Introduction

33.2.2.4 .4 RS232 Interface

Either a printer (for protocolling the changer settings and methods)

or a personal computer (for controlling the changer) can be con-

nected to the RS232 Interface. Furthermore, other Metrohm in-

struments (via Metrohm remote control language) and possibly

other foreign instruments can be accessed via this interface. The

transfer parameters required, which must be adjusted according to

the instrument which is being connected, are the following:

Baud Rate, Data Bit, Stop Bit, Parity and Handshake

For data communication with PC's, Metrohm and foreign instru-

ments, the parameter 'send to: IBM' must be set. The remaining

parameters should keep the standard value or be adapted to the

settings of the peripheral instrument used.

For connecting a printer, see page 25.

With 'RS control: ON' the reception of data can be switched on

and off. If the remote control is switched off, data cannot be re-

ceived any more, but reports can still be printed.

33.2.2.5 .5 Locking Keyboard Functions

Certain domains of the user dialog can be made inaccessible to

the novice user by locking particular keys. For example, the inad-

vertent overwriting of a method or even the changing of parame-

ters can be prevented in this way.

The menu 'keyboard options' for the corresponding functions is

opened by holding down the <CONFIG> key while turning on the

changer. Alternatively, a reset can be executed by pressing

<CLEAR> and then the <CONFIG> key within 0.4 seconds. This

menu is also accessible when the entire keyboard has been

locked.

The individual key domains that can be locked are the following:

1 2 ... 38 39 40 41 42 43 44 45 46 47 48 ... 194 195
