Carrier transceivers are designed to be used only with certain antenna products. Other higher gain directional antennas may be purchased through an approved Carrier supplier. Contact Carrier for additional information. Installation onto a CCN Bus — Use the RS-232 to RS-485 converter to install transceivers directly onto an RS-485 network. An RS-232 to RS-485 converter and power supply is supplied with each transceiver. 1. Separate the RS-485 converter’s housing with a flat blade screw driver. 2. Install jumpers in all 5 terminals. 3. Wire the CCN (+) to screw terminal Pin 1, and CCN (-) to screw terminal Pin 2. See Fig. 2. 4. Cut the power plug off of the power cube 6 in. from the end. 5. Wire the ground wire of the power supply wire to screw terminal Pin 5 and the positive (wire with white line) to screw terminal Pin 6. See Fig 2. If a transceiver is used to connect directly to a computer, an RS-232 to RS-485 converter is not required. Only the 9-pin cable (supplied) is used. 12 3 5 4 6 78 910 x x x x x CCN (+) V (+)V (GND) RED CCN (-) BLACK LEGEND CCN — Carrier Comfort Network GND — Ground (-) NOTES: 1. Install end of line termination jumpers between 1 and 2, 3 and 4 if unit is used with the RS-485 network. 2. Install jumpers between 5 and 6, 7 and 8, 9 and 10 to use the converter in a CCN 2 wire set up. Fig. 2 — Converter Detail NETWORK TOPOLOGY The Carrier transceivers support the Broadcast Network topology. Each transceiver can be configured via its Configuration Manager to work this topology. The transceiver’s Configuration Manager controls how the transceiver transmits and receives data as connected to the device. (See Fig. 3-5.) Wireless communication signals can be adversely affected by physical and/or electrical interference. Carrier wireless transceivers should NOT be installed in applications where temporary loss of communications cannot be tolerated by the control system. Suitable applications include equipment monitoring, alarm monitoring, control overrides and temporary service connections. Networks — Wireless data connectivity applications require a wide range of networking options. The network topologies consist of more than two transceivers and may have a PC to host a network of devices. The PC or network devices are each physically attached to a transceiver. WIRELESS SERVICE TOOL — The wireless Service Tool setup allows a CCN service technician to install, commission, and troubleshoot from any location in the building. All CCN elements on the primary bus are accessible. The wireless connection allows the technician to utilize a laptop computer to perform all Service Tool functions from anywhere within the range of wireless communication. If the transceiver is located on a rooftop, it is possible to gain wireless access to the building from several miles away. NOTE: Wireless buss extensions on CCN systems with secondary buses are recommended for temporary use only. Permanent use is NOT recommended. WIRELESS BUS EXTENSION — The wireless bus extension setup allows a bus to be extended to a remote location through the use of the wireless transceivers. This set up can be used to connect two portions of a CCN bus when physical wiring cannot be used or is not cost effective. This set up may also be used to connect controllers in two different buildings by placing the transceiver on the roofs of the buildings. This set up is not recommended for CCN systems that contain secondary buses. 4 NOTE: Not recommended for use on sites with secondary buses. Fig. 3 — Wireless Multiple Bus Extensions of Primary Bus NOTE: Not recommended for use on sites with secondary buses. Fig. 4 — Wireless Workstation NOTE: Not recommended for use on sites with secondary buses. Fig. 5 — Wireless Bus Extension of Primary Bus 5 Wireless links can only be used to extend a CCN primary bus (bus D). Do not use bridges when using a wireless link. Utilizing this primary bus wireless connection to access CCN devices through a bridge will cause communication messages to be generated on the primary bus. The wireless bus extension setup allows primary bus to be extended to a remote location through the use of wireless technology. This set up can be used to connect two portions of a CCN primary bus when utilizing physical wire may be a costly or difficult task. This set up may be used to connected controllers within a building or to another building by placing the modems on the roofs of the structures. A wireless bus extension on a CCN primary bus is only recommended if there are no CCN secondary busses. If CCN bridges are installed a wireless extension of the primary bus is not recommended. BROADCAST NETWORK — In a Broadcast Network, data is sent out by one transceiver (sending transceiver) and received by an unlimited number of remote devices simultaneously. These devices must be intelligent enough to recognize relevant messages and recover lost or corrupted data. Broadcast Networks operate solely as configured by the Configuration ...
