Introduction

This Tech Note describes how to configure Crimson to support:
•BACnet MS/TP: Serial Communications (analog and binary (i.e., digital)
•BACnet UDP/IP or 802.3 (Raw): Ethernet Communications (analog and binary)

NOTE: Crimson is required and is only available to Windows 2000 or above users. Please update your version of Crimson to the latest, available online at: www.redlion.net.

BACnet MS/TP: Serial Communications

This section describes how to configure BACnet slave drivers within Crimson to support BACnet MS/TP: Serial Communications, for both analog data transfer and binary (digital) data transfer. Refer to steps1 thru 16 for configuring drivers for analog data transfer, and to steps 17 thru 26 for configuring drivers for binary data transfer.

Analog Data Transfer

1. Referring to Figure 1, go to the Navigation Pane and click on the Communications Port to be configured; RS485 Comms Port in this example.
2. Go to the Communications - RS-485 Comms Port window and under the Driver Selection heading select the Pick button, next to the Driver: field.
3. Go to the Driver Picker for Serial Port popup and under the Manufacturer heading select BACnet, and under the Driver heading select MS/TP Slave.

Figure 1.

4. Click OK.
5. Referring to Figure 2, configure the port settings to match the device with which the unit will be communicating:

a. The MAC Address: and Device ID: fields under the Configuration heading refer to the Red Lion device that is being programmed; 10 and 127, respectively, in this example.
b. The Max Instance: field is the number of each data type that can be auto-discovered on the network; 100 in this example.
c. The Object Properties settings are used to select how the exposed data items will be named during an auto discovery, as well as what extra information will be discovered. See each item’s bubble help for further information.
d. The Remote Management Password is used for the BACnet Reinitialize Device commands; both cold start and warm start are supported. The default value is "password".
