774 Oven Sample Processor, Instructions for use

Control commands:
CTL:Rm : START Gerät1
starts
Titrino
CTL:Rm : ***********1**
advance impulse / ENTER
Scanning via remote lines:
SCN:Rm : ****1000
waits for end of titration (EOD-impulse)
SCN:Rm : *****010
waits for 'cond. ok'
In principle it is possible to use an additional RS232 connection to auto-
matically load a particular method in the Titrino while a sequence is being
processed. Please refer to the example of the remote connection given for
the 756 Coulometer on the previous page.
774 Oven Sample Processor — 796 Titroprocessor
for volumetric KF titrations
If connected to a 774 Oven Sample Processor the 796 Titroprocessor takes
over the functions of the control instrument itself (Master). The communica-
tion between the 774 Oven Sample Processor and the 796 Titroprocessor
can be solved in any manner.
If a remote connection is used (6.2141.020 cable) the input and output lines
0…7 can be used as required. However, it is then not possible to start a
774 Oven Sample Processor method. See page 79ff for the communication
commands.
A serial RS232 connection between the 796 Titroprocessor and the 774
Oven Sample Processor has the advantage that the Titroprocessor as con-
trol unit can access all internal functions except starting or loading a
method in the 774 Oven Sample Processor. Please refer to the description
of the Metrohm remote language and the 774 remote control tree on page
98ff.
