Autostart pulse control
In order to guarantee an unattended remote control of the 865 Dosimat
plus, the parameter "Autostart at power-on" can be activated. The instru-
ment thus starts the loaded method immediately after switching on and is
ready to receive and carry out dosing pulses. Pressing the [GO] key for
starting the method is therefore not necessary.
Manual interventions
Manual dosing is not possible with activated pulse control. The [GO] key
is deactivated. The [FILL] key triggers the filling of the cylinder and at the
same time finishes the method.
During a method run, modifying certain parameters is possible as it is in
manual dosing.
The instrument shows the "Hold" status during pulse control.
Deactivated parameters
Parameters which directly affect the dosing are inactive during pulse con-
trol operation. This includes:
￭ Dosing rate
￭ Dosing ramp
8.8 Remote control via an RS-232 connection
The 865 Dosimat plus can be remote controlled via an RS-232 connection.
For this, a 6.2148.030 RS-232/USB Box is necessary. Connect the
RS-232/USB Box to the USB interface of the instrument.
The RS-232/USB Box has two connectors for RS-232 devices. The RS-232
remote control only works via the RS-232/2 connector. The RS-232/1
connector is provided for a connection to a balance. Connect the
RS-232/2 connector of the RS-232/USB Box to a serial interface (COM1
or COM2, designated with the symbol IOIO) of a PC. Use a 6.2134.040
connection cable.
