ASCII interface
This section describes the ASCII interface of the Intesis, its configuration and functionality.
3.1 Description
The gateway can be connected to any
ASCII enabled
device using its EIA232 interface (DB9 connector DTE), EIA485
interface or TCP/IP (Ethernet connector) and offers through this interface the possibility of supervision and control of its
internal BACnet points using simple ASCII messages.
On receiving messages corresponding to write commands in its ASCII interface, the gateway sends the corresponding
write command message to the associated BACnet device.
When a new value for a point is received from BACnet, the corresponding ASCII message indicating the new value will
be sent through the ASCII interface, but only if the point is configured for sending this "spontaneous messages", if it is
not configured to do so, then the new value will be available to be polled in any moment from the ASCII enabled device
connected to this ASCII interface. This behaviour of sending or not through the ASCII interface the new values received
from BACnet is configurable individually per point in the gateway.
3.2 ASCII Serial
Serial communication for the ASCII communication can be configured to match the ASCII master device.
Only the RX, TX and GND lines of the EIA232 connector are used (TX/RX+ and TX/RX- for EIA485).
3.3 ASCII TCP
The TCP port to use can be configured (by default 5000 is used).
The IP address, subnet mask and default router address to use by Intesis can be also configured.
3.4 Address Map
The ASCII address map is fully configurable; any point in the Intesis can be freely configured with the desired internal
register address. Check the configuration tool manual for more information.
3.5 Points definition
Every point defined in the gateway has the following ASCII features associated to it, which can be configured:
