M E S H A N D B R I D G E Chapter N O D E S Mesh/Bridge Nodes This chapter describes the hardware features of Mesh/Bridge nodes. S ensicast Mesh nodes can function either as network coordinators or as sensing/actuating nodes. As a coordinator, the Mesh node automatically configures itself into a wireless mesh network with primary and secondary redundant connections. As a node, the Mesh node wirelessly transmits data from third-party sensors and receives control commands for device actuation.
M E S H A N D B R I D G E N O D E S Power Supply The power supply is a 120VAC/60Hz in, 6V DC out adapter that is used as the primary power source for the Mesh/Bridge node. Serial Cable The serial cable includes a stereo jack on one end and a standard DB9 connector on the other end. The stereo jack can be plugged into the node, while the DB9 connector can be plugged into a PC serial port. Note The serial cable is an option on the Mesh node; it is standard on the Bridge node. www.sensicast.
M E S H A N D B R I D G E N O D E S Physical Interface The physical interface includes the housing, mounting options, switches, connectors, LEDs, and other features. A number of key features are described in the sections below. Front- Cover Closed Figure 2-1 shows the front of a Mesh node and a Bridge node with their covers closed. FIGURE 2-1: FRONT OF MESH NODE (PURPLE)/BRIDGE NODE (ORANGE)- COVER CLOSED.
M E S H A N D B R I D G E N O D E S Front- Cover Open Figure 2-2 shows the front of a Mesh/Bridge node with its cover open. FIGURE 2-2: FRONT OF MESH/BRIDGE NODE- COVER OPEN. As shown in Figure 2-2, features on the inside of a Mesh/Bridge node include the battery well, the battery connector, and the power switch. www.sensicast.
M E S H A N D B R I D G E N O D E S Back Figure 2-3 shows the back of a Mesh/Bridge node. FIGURE 2-3: BACK OF MESH/BRIDGE NODE. As shown in Figure 2-3, the main features on the back of a Mesh/Bridge node are the power switch and rear power access. There is a barcode label on the back of a Mesh/Bridge node. This label contains the node ID and the association key for the node. The association key is entered into the database when the node is added to the network.
M E S H A N D B R I D G E N O D E S Electrical Interface The electrical interface includes internal and external connectors, as described below. Internal Connector Figure 2-4 shows the internal electrical interface for the Mesh/Bridge node. FIGURE 2-4: INSIDE OF MESH/BRIDGE NODE SHOWING INTERNAL ELECTRICAL INTERFACE. The internal connector is a two-position screw terminal used to connect DC power from the rear of the device.
M E S H A N D B R I D G E N O D E S External Connectors Figure 2-5 shows the external electrical interface for the Mesh node and the Bridge node. FIGURE 2-5: FRONT OF MESH NODE AND BRIDGE NODE SHOWING EXTERNAL ELECTRICAL INTERFACE. External connectors include a DC IN, a stereo jack, and two different screw terminals. www.sensicast.
M E S H A N D B R I D G E N O D E S DC IN The DC IN is a barrel connector designed to accept the connector on the Sensicast 6V DC power supply. The center conductor is positive; the outer conductor is ground. Note Be careful not to insert the power connector into the serial jack. Stereo Jack 10101 The 10101 stereo jack is designed to accept the stereo plug on Sensicast serial cable. Note The serial cable is an option on the Mesh node; it is standard on the Bridge node. www.sensicast.
M E S H A N D B R I D G E N O D E S Screw Terminal A Screw Terminal A is a two-position screw terminal that is used to provide power out. The voltage is the node’s supply voltage (nominally 3V). The terminal marked with a “+” sign is the positive voltage out; the other is ground. The node’s microprocessor can instead use Screw Terminal A as the output of a normally open (Form A) solid-state relay. When used as a relay, the maximum voltage that can be applied to the terminal is 18V.
M E S H A N D B R I D G E N O D E S Hardware Operation: What to Do/What to Avoid The following sections describe some tips for hardware operation, including information about what not to do when using the Mesh/Bridge node. Opening/Closing Node Cover To open the node, loosen the screw in the center of the unit and tilt the cover up. The cover is hinged along the top. To close the lid, first fit the top of the cover over the top edge of the base to form a hinge, then swing the lid down into place.
M E S H A N D B R I D G E N O D E S Resetting the Mesh/Bridge Node To reset the circuitry, turn the node off, wait for 3 seconds, and turn the node on again. Mounting the Mesh/Bridge Node Use the enclosed #4 wood screws to mount the node using one or both of the mounting holes. The unit may also be attached using adhesives or double sided tape, allowing for the fact that the device weighs 4.5 ounces.
M E S H A N D B R I D G E N O D E S Serial Connection To use a serial connection with the Mesh/Bridge node, insert the stereo plug end of the Sensicast serial cable into the connector on the front of the node marked “10101”. Connect the DB9 connector to your DTE serial device (e.g., a personal computer). The signals are RS232 levels. Note The serial cable is an option on the Mesh node; it is standard on the Bridge node.
O A S / E M S Chapter N O D E S OAS/EMS Nodes This chapter describes the hardware features of OAS/EMS nodes. S ensicast Object Alarm System (OAS)/Environmental Monitoring System (EMS) nodes report accurate, real-time data on touch, temperature, and humidity to a central management application. OAS/EMS nodes are user-configurable, allowing the user to adjust remotely the desired data transmission interval for specific applications.
O A S / E M S N O D E S Touch Sensors One or two touch sensors can be attached to the node. Figure 3-1 shows a Sensicast touch sensor. FIGURE 3-1: SENSICAST TOUCH SENSOR. Note Touch sensors are an option for OAS nodes only. www.sensicast.
O A S / E M S N O D E S Physical Interface The physical interface includes the housing, mounting options, switches, connectors, LEDs, and other features. A number of key features are described in the sections below. Front- Cover Closed Figure 3-2 shows the front of an OAS node and an EMS node with their covers closed. FIGURE 3-2: FRONT OF OAS NODE (RED)/EMS NODE (BROWN)- COVER CLOSED.
O A S / E M S N O D E S Front- Cover Open Figure 3-3 shows the front of an OAS/EMS node with its cover open. FIGURE 3-3: FRONT OF OAS/EMS NODE- COVER OPEN. As shown in Figure 3-3, features on the inside of an OAS/EMS node include the battery well, the battery connector, and the power switch. www.sensicast.
O A S / E M S N O D E S Back Figure 3-4 shows the back of an OAS/EMS node. FIGURE 3-4: BACK OF OAS/EMS NODE. As shown in Figure 3-4, the main feature on the back of an OAS/EMS node is the power switch. There is a barcode label on the back of an OAS/EMS node. This label contains the node ID and the association key for the node. The association key is entered into the database when the node is added to the network. When a node asks permission to join the network, it sends its node ID to the host.
O A S / E M S N O D E S Electrical Interface Figure 3-5 shows the electrical interface for the OAS node and the EMS node. FIGURE 3-5: FRONT OF OAS NODE AND EMS NODE SHOWING ELECTRICAL INTERFACE. Each of the electrical interface connectors is a two-position screw terminal. www.sensicast.
O A S / E M S N O D E S OUT The terminals labeled “OUT” are the two terminals of a normally open (Form A) solid-state relay under the control of the node’s microprocessor. The maximum voltage that can be applied to either of the terminals is 18V. The maximum load the relay can conduct is 100mA. The maximum resistance when closed is 35 ohms. IN AUX The terminals labeled “AUX” are designed to connect to either normally open (Form A) or normally closed (Form B) dry contact sensors.
O A S / E M S N O D E S Hardware Operation: What to Do/What to Avoid The following sections describe some tips for hardware operation, including information about what not to do when using the Mesh/Bridge node.
