Blue Sky Energy – Universal Communication Module UCM CONNECTIONS AND INDICATORS Ethernet connector: Connects to router with Cat-5 patch cable, or directly to computer with supplied crossover type Ethernet cable. LINK LED indicates communication link established. ACT LED indicates communication activity occurring. IPN Network connector: UCM power & IPN network communication. MUST be connected to properly powered IPN compatible charge controller for UCM to operate.
Installation and Operation Manual CROSSOVER & STRAIGHT-THRU ETHERNET CABLES COMPUTER OR UCM ROUTER STRAIGHT-THRU PATCH CABLE COMPUTER FIGURE 3 UCM CROSSOVER CABLE ¾ CAUTION: Do not plug the UCM’s Ethernet connector into anything other than a 10baseT Ethernet compatible computer, router or similar 10baseT Ethernet compatible device or damage may result which will void the limited warranty. Utilizing good wiring practices total maximum cable length should be limited to 329 feet (100m).
Blue Sky Energy – Universal Communication Module 2b) Windows 7 ― Configure computer’s TCP/IP settings for direct connection with UCM For Windows 7 operating system go to Control Panel, and under Network and Internet category select View Network Status and Tasks. From within the Network and Sharing Center window that appears select Change Adapter Settings. Right click on Local Area Connection and select Properties.
Installation and Operation Manual 5) Restore computer TCP/IP settings to their original settings When finished with direct connect communication restore the computer’s original Internet Protocol (TCP/IP) Properties settings recorded above which are likely Obtain an IP Address Automatically and Obtain DNS Server Address Automatically. If these settings are not restored the computer will not be able to communicate with a hard wired connection to the router or the internet.
Blue Sky Energy – Universal Communication Module This typically requires that you go to the routers DCHP status or setup page to see the IP Addresses that the router has assigned to computers or other devices on your LAN via DCHP (Dynamic Host Configuration Protocol). IP Addresses are four numbers separated by periods and may be something like 192.168.0.xxx where xxx must be different for each device on your LAN.
Installation and Operation Manual Enter the password and select Submit. Default password is admin. If the password is accepted you will be presented with an Enter Remote button. Select Enter Remote to go to the Top Menu page. Once logged onto the UCM’s web site there are five available pages The first four pages are essentially same as the four menus of the IPN-ProRemote. The fifth page, UCM Setup, is for configuring UCM communications and password settings.
Blue Sky Energy – Universal Communication Module USING THE IPN-ProRemote WITH A UCM An IPN-ProRemote display may or may not be present in the system. If an IPN-ProRemote is present its full featured battery monitoring functionality become available through the UCM.
Installation and Operation Manual ADVANCED DISPLAY WEB PAGE User defined Location Name reminder. Days since last full charge or equalize. Equalize day counter resets upon starting equalize. Day counter accuracy is +1 / -0 days. Day counter transitions occur following each 24 hour period from charge controller boot. Consider rebooting charge controller very late at night to improve perceived accuracy. Maximum range is 255 days which is also shown if days are unknown.
Blue Sky Energy – Universal Communication Module SETUP WEB PAGE Total battery Amp-Hour rating at 25°C, 20hr rate. Stored in and used by IPN-ProRemote. With charge efficiency set to 94%, battery is expected to retain 94 Amp-Hours for each 100 Amp-Hours of charge delivered. With charge efficiency mode set to FIXED, charge efficiency value remains as set. If set to AUTO charge efficiency automatically adjusts based on observed battery charge efficiency. Stored and used by IPNProRemote.
Installation and Operation Manual BATTERY CHARGE PARAMETERS WEB PAGE ¾ CAUTION: Refer to charge controller operators manual for further detail regarding charge control operation. Set battery charge parameters to values specified by the battery manufacturer. Acceptance charge voltage setpoint. Range 10.0 to 80.0V. Float charge voltage setpoint. Range 10.0 to 80.0V. User defined Location Name reminder. Equalize charge voltage setpoint. Range 10.0 to 80.0V. Equalize time setpoint. Range 0.5 to 10.0 hours.
Blue Sky Energy – Universal Communication Module UCM SETUP WEB PAGE UCM password, required for UCM access. Default password is admin. Location Name reminder (e.g., ROAD SIGN #42). Appears below Remote Access on all pages except UCM Setup page to remind users of multiple UCM’s which particular UCM is being viewed. FTP communication settings. Factory defaults are shown. FTP used for periodic upload of real-time data to remote server. Setting range 0.0 – 24.0 hours. A setting of 0.
Installation and Operation Manual DATALOG FILE CONTENTS The CSV datalog file as viewed in a spreadsheet such as Excel is organized into rows and columns. Each row is a single datalog record. Each record contains a variety of data values which are presented in columns. If a data value in a record is unavailable that cell will contain dashes (――). Each data item is the minimum, maximum, total, etc., for that data record time period. Spreadsheet column A contains the record number.
Blue Sky Energy – Universal Communication Module FTP COMMUNICATION SETTINGS The following setup information needs to be entered into the FTP Data File Transfer section of the UCM Setup web page for FTP file transfer. If necessary, contact your IT administrator or FTP Server provider for the required information and how to download the files to your local computer. Blue Sky Energy does not provide FTP download software or endorse any particular FTP download software.
Installation and Operation Manual MODBUS OVER TCP The UCM communicates on port 502. The Slave Address / Unit Identifier only applies if MODBUS/TCP communication is converted back to RS-485 by an external user supplied TCP to RS-485 converter. SLAVE ADDRESS / UNIT IDENTIFIER DIP switches AD0 through AD7 as shown in Figure 4 set the UCM’s RS-485 RTU Slave Address / Unit Identifier within a selectable range of 1-247. Factory default Slave Address / Unit Identifier is 1 (AD0 - AD7 all OFF).
