Description The OE415-02 IP Module Kit (when installed and configured in the CommLink IV communication inter-face) provides TCP/IP Internet and/or intranet con-nection for Ethernet networked computer systems allowing them to communicate with your control sys-tem. The OE415-02 IP Module Kit consists of the IP Module and a 10 ft. long CAT5 Ethernet crossover cable. The IP Module plugs into a mating 40 pin (2 x 20) connector located on the CommLink IV circuit board. Installation is easily accomplished by removing the CommLink IV case cover screws, removing the case cover to access the circuit board, and then plugging the IP Module into its mating socket connector. Cor-rect alignment is made easy because of the (4) slot alignment tabs located around the perimeter of the processor base. It is not possible to incorrectly align the IP Module to the socket connector because of this feature. The TCP/IP connection provided by the IP Module installed in the CommLink IV is a TCP connection on a single port number and is static in nature. Firewall and proxy servers can easily be configured to allow traffic to and from the CommLink IV when the IP module is installed. The nature of the data is raw in form and comprised of packets native to Prism soft-ware. The IP Module will respond to ICMP traffic (PING) for verification of proper configuration. Prism software is required in order to read and send data to the IP module and through the CommLink IV to the control system. The IP Module connects to the host Ethernet system by means of the supplied 10 ft. long CAT 5 Ethernet crossover cable which plugs into the 10/100 Base-T, RJ-45 jack on the back of the CommLink IV and into a Ethernet router or Ethernet modem on your building’s LAN. Setup of the CommLink IV with the IP Module requires a knowledgeable IT person familiar with configuring network adapters and TCP/IP systems. Prism software must be installed on the local LAN computer(s) and/or remote Internet computers that will be used to program and monitor the control system.

Description The OE419-06 Remote Link II is essentially a 14,400 baud modem that connects to the CommLink IV via a serial cable. When it is used as a modem (at the remote computer lo-cation) it connects to the remote computer via a USB cable. The Remote Link II is used to provide for remote dial-up communications with the CommLink II or CommLink IV com-munication interfaces. The Remote Link II connects to the CommLink II or IV communications interface at the control system location. A telephone line connects the Remote Link II to the local phone service. By dialing the telephone number at the job site that the Remote Link II is connected to (using another Remote Link II modem from a remote location), the control system can be monitored and controlled using the Prism computer front end software package.

Mounting The Remote Link II should be mounted close to a serviceable telephone outlet. The CommLink II or CommLink IV communications interface connects to the Remote Link II with the supplied 6 ft. long serial cable. It is recommended that a second Remote Link II be used as the dial out modem at the remote computer location. WattMaster will not support any other internal or external modems by other manufacturers. A 6 ft. long USB cable is sup-plied with the Remote Link II to connect to the remote computer USB port when the Remote Link II is used at the remote computer location. If an on-site computer at the job location is re-quired, it should be connected to the CommLink II or IV at or near the location where the Remote Link II is located, for ease of connection. If you need to use a longer serial or USB cable, you will need to purchase these from an electronics supply store. Do not use any USB or serial cables longer than 25 ft.

Auto-Zone Control Systems

Description The OE366 USB-Link allows computer access into the Auto-Zone controls system and also provides commu-nications across multiple local communications loops on the control system when a CommLink Communica-tions Interface is installed on the system. The USB-Link provides a direct link to enable the sys-tem operator to view the status and to configure and adjust the setpoints of any controller on the control system communications loop using the Prism II com-puter front end software. The USB-Link is small in size and is powered by the USB port of the computer it is plugged into, making it completely portable and allowing connection to the system from any controller. The USB-Link is supplied with a USB cable, a mini-DIN male communication cable, and two mini-DIN to terminal adapters. The communication cable allows the user to walk up to any controller that has a com-munication socket and plug in the USB-Link to gain access to the system. The adapters are used for boards that do not have a female mini-DIN plug con-nection.

To use the USB-Link, you will need a computer with an available USB 1.1 or 2.0 port with the included USB drivers installed. You will also need the Prism II com-puter front end software installed on the computer.

CAUTION: The USB-Link does not work with Prism I software. It only works with Prism II.

*Chart Notes:1. Use the resistance column to check the thermistor sensor while disconnected from the controllers (not powered).

2. Use the voltage column to check sensors while connected to powered controllers. Read voltage with meter set on DC volts.Place the "-"(minus) lead on GND terminal and the "+"(plus) lead on the sensor input terminal being investigated. If the voltageis above 5.08 VDC, the sensor or wiring is "open." If the voltage is less than 0.05 VDC, the sensor or wiring is shorted.

The Duct Sensor Is Used For Sensing SupplyOr Return Air Temperatures. Location Of TheSensors Is Very Important In Order To ObtainAccurate Temperature Readings. TheFollowing Recommendations Should BeFollowed:

When Used As A Supply Air Sensor TheSensor Should Be Mounted In The Supply AirDuct As Close To The HVAC Unit As PossibleAnd Upstream Of The Bypass Damper (IfUsed) For Best Results.

2.)Unused Conduit Opening(s) MustHave Closure Plugs Installed And MustBe Coated with Sealing Compound ToProvide Raintight Seal. Water CanDamage Sensor!

1.)The Outside Air Sensor Must BeMounted In A Vertical Position AsShown (Sensor Tube PointingDown).

Sensor Must Be LocatedWhere It Will Not Be Affected ByDirect Sunlight Or Heat ProducingEquipment. If Possible Mount UnderRoof Eave Or Similar ProtectedLocation. If Sensor Is Not LocatedAs Specified, Erroneous Outside AirTemperature Readings Will Result.

Water Must Not BeAllowed To Stand In SensorTube. Rainwater Will DamageSensor.

*Chart Notes:1. Use the resistance column to check the thermistor sensor while disconnected from the controllers (not powered).

2. Use the voltage column to check sensors while connected to powered controllers. Read voltage with meter set on DCvolts. Place the "-"(minus) lead on GND terminal and the "+"(plus) lead on the sensor input terminal being investigated. Ifthe voltage is above 5.08 VDC, then the sensor or wiring is "open." If the voltage is less than 0.05 VDC, the sensor orwiring is shorted.
