3.3.3. OPERATION
For initial operation the internal mode switches should be set as above with the security switches set to the OFF position.
The power to the Model 2000 is switched on, the main Model 2000 display will indicate a start up message. This will indicate
if the Model 2000 is capable of operating and has sufficient data or requires data and set-up to be initialised. Initialisation
and Set-up of a Model 2000 is achieved using the operating PC software for the Model 2000 in conjunction with an Infra red
communication adapter and the communication port on the front of the Model 2000. In its default mode the Model 2000
communication set-up is as follows:-
Comms id of 0
Baud rate of 38400
Most IrDa communication adapters will normally initially operate at the default baud rates of 9600.
Selected types of IrDa adapter can be set to operate at higher baud rates by using the Main Menu SYSTEM option (See
paragraph 2.3.10). The supported types are:-
BS Instruments Ltd Type 2000-3-070 Fixed baud rate of 38400 (See Figure 21 for details)
Parallax Research PRA 9500C Up to 115k baud
Once the PC system has been initialised and the operating software started, the Infra red adapter should be positioned
within 1-2 metre's from the Model 2000 communication port in direct line of sight. The instructions on the operating software
for setting up and programming should be followed.
As an alternative to the Infra Red Cable that has to be connected to a COM X port of the PC a USB terminated device is also
available.
BS Instruments Ltd Type 2000-3-075 Fixed baud rate of 38400
Use of this device requires appropriate Software Drivers to be installed on the operating PC. These are supplied with the
Cable complete with installation instructions. Model 2000 Units supplied after the end of 2004 will be equipped with a USB
type “A” connection on the front panel replacing the Infra Red Window. In this case connection to a PC is achieved by using
an A to A USB cable, this is supplied with the Model 2000. See figures 24 and 25 for details.
3.4. SOFTWARE INSTALLATION
If it becomes necessary to update or re-install the operating software inside the Model 2000 the mode switches should be set
as below. Explicit instructions for this function are given in a Technical Manual separate from this manual and should only
be carried out by personnel familiar with the function. Programming Boot mode:-
Switch No. ON OFF
1 Security 1 Off Security 1 On
2 Irda Infra Red or Front Panel USB

3.5. CALIBRATION
3.5.1. INPUT SIGNALS
3.5.1.1. DIGITAL INPUT SIGNALS
The Model 2000 Flow Computer does not require calibrating for any of the pulse inputs from meters as these inputs use a
digital format.
3.5.1.2. HART INPUT SIGNALS
The Hart pressure and temperature transmitters must be calibrated themselves in accordance with the manufacturers
instructions. The transmitters are connected to the Model 2000 in parallel as a multidrop system and each transmitter must
have a different address. It is essential that the transmitters have their addresses programmed and the burst mode
operation turned off before they are connected to the Model 2000. Use the Rosemount Smart Family Interface Model 268 to
programme and calibrate the transmitters referring to the Rosemount operating manuals for the programming procedures.
It is possible to Calibrate the Hart transmitters once they are in use these is done using the Calibrate Main menu option. This
menu item when selected will allow access to the Input parameters that will require calibration via the Keyboard and Display
of the Model 2000. When this menu item is selected the user will be prompted to enter a four digit numeric password, to gain
access to the calibration pages. It is possible to set-up a maximum of three different passwords and each of these passwords
can be set to allow access or not to the calibration pages, these passwords are the same as used in the EDIT mode.
In its factory default condition the three available passwords are 1111, 2222 and 3333.
