Crestron e-control Database Manager SW-DBM

42 •• Demos Installation & Reference Guide — DOC. 5823

• A compiled control system program file which uses serial RS-232

communications (demo?COM.bin file); derived from the above by

commenting off the Virtual COM port; ready to upload to such a control system.

• A compiled control system program file which uses EtherNet communications

(demo?TCP.bin file); derived from the above by commenting off the serial

COM port; ready to upload to such a control system.

The supplied SIMPL and VT Pro-e files may require conversion prior to compiling

and uploading if your target touchpanel is not one of those mentioned above.

Conversion is a simple matter using VT Pro-e.

Before attempting to run the demos, use the File | Configuration File… command

to make sure the server is using the configuration file named above.

Demo 1 Database Browsing and Maintenance

This demo illustrates browsing a table with the ability to add, delete, and update

records. To enable database maintenance operations, you must check the Edit

symbols checkbox in the Scroller Signal Block Definition window.

The scroller in the demo has six rows, and lists Crestron offices around the world.

When the user picks row n, a Pickn signal is sent to the server, which sends the

corresponding datafields to the touchscreen.

Selecting a data field displays a virtual keyboard that lets you enter new information

for that field. Clicking OK on the keyboard when finished typing closes the

keyboard, enters the text the user typed in the datafield on the touchscreen and sends

a WriteField signal to the server that updates the database record. (In a future

release, the table will not be updated until the server receives an UpdateRec signal.)

Selecting the Add a new record button sends a NewRec signal to the server,

which creates a new empty database record. Add information by selecting each data

field and using the keyboard to update the blank datafields.

Selecting a record and pressing Delete this record sends a DeleteRec signal to the

server and deletes the row from the database table.

Demo 1 SIMPL Windows Program

Two items need to be added to the control system in the Configuration Manager in

SIMPL Windows. From the Control Systems folder in the Device Library select

CNMSX-AV; and also add a two-way serial driver to a COM port on the CNXCOM-

6 board from the Serial Drivers (General) folder (or add a Virtual Communication

Port from the Ethernet Control Modules folder and a driver as above).

In the Programming Manager, the other blocks are added to the system from the

Logic Symbols folder in the Symbol Library. Interlock and Set/Reset Latch are

selected from the Memory folder. Intersystem Communications w/offset is selected

from the System Control folder.

Demo 1 VT Pro-e Program

The first page of demo 1 gives you the choice of starting the demo or returning to the

main menu.
