RGX Communications Server 2

1.0 RGX OVERVIEW

The RGX card was developed to act as a communications gateway for the CR-110 refrigera-tion card and the ER-110 evaporator controller. It may also be used with other types of con-trollers. The primary operation of the RGX is to poll up to 10 devices on a RS-485 communi-cations bus and then make the data available via a UDP network connection, HTTP embed-ded web server, TCP modbus network and RS-485 modbus connection. The RGX also has a RS-485 port that will translate data to a second RS-485 port that is used for polling control cards. The RGX has an embedded web server that will display all data and allow changes on a web page with three levels of security. The embedded web server will also send text messages for alarms and updates. The network connection also allows a variety of remote software and data collection to poll the devices. A spreadsheet file is the driver for all the card types and datapoint setups. This file can be configured for a specific application and then downloaded via the network connection to the RGX. The RGX uses a 64MB picture card for nonvolatile memory and has the ability to store a large number of records for each of the devices.

5.0 RGX NETWORK CONNECTION

The RGX network connection is on the plug-in Rabbit processor card: You can plug your laptop directly into the network connection us-ing a null cable or you can plug the RGX card into a router or switch. A wireless Bridge may also be used to provide a network connection to the RGX.

With the proper network connection, you should be able to use any web browser and type in the IP address http://192.168.1.50 and access the login page. Use the username user1 And password pass1 The following page will describe how to access the page if the IP and username and or pass-word are unknown.



6.0 RGX BACKDOOR

The RGX is setup using a network connection and web browser. The default IP address is 192.168.1.50 and comes from the factory with three usernames and passwords all set for full control. Factory defaults: IP 192.168.1.50 port 80 User name Password user1 pass1 user2 pass2 user3 pass3 If the usernames, passwords or IP addresses are changed and lost you can default the RGX using a Jumper on 4 & 7 on Jack J5. To activate the backdoor on the RGX, power the card down and install a Jumper as shown on J5. Power the unit up and access the card using the default address on your web browser (http://192.168.1.50). You should then get a username and password box. Once you have accessed the card and put in new IP and security settings, power the card down, remove the jumper and power back up.

With the jumper in use rgx for both the username and password. This will allow you full access to set the card up.



7.0 RGX WEB INTERFACE

Once you access the web page, you should see the main page.

The main page is configured using a spreadsheet. You can label and setup the page as you desire. The specifics of this setup page is described later in this manual. You can display up to 10 devices on the main or summary page. To view more detail or make program changes click on the unit under the Name column.

The Detail page contains more information for each of the units. Click on Modify Values to make program changes.



The modify screen allows you to change any of the values listed. To modify a value, change the value and then click on Update. If for some rea-son the program change does not work, you will get a Write Fail screen. Some devices such as the CR and ER cards can be reset using the Reset Card button.

7.1 RGX WEB INTERFACE RECORDS

The RGX can store up to 10,000 records for each of the 10 possible devices. Each device has its own set of records. Average Historical records are triggered at a specific time interval. You can also create activity records that are instantaneous re-cords that are triggered by a mode or status change for the unit. There are two choices to download the records. One is to use the Start date and End date. The other is to download the last seven days. The last seven days is primarily used for Excel templates.

The Start date and End date are at midnight. So today's start date and tomorrows end date will give you today’s data. When you click on Retrieve records, you should get the following screen.



At this point you can save the records or open the records in Excel. After a short time you should get the records in the following format. You can auto adjust all the column’s by double clicking on the division between A and B.

The order and selection of the parameters for the records can be changed in the csv set up file. This file is described later in this manual.



8.0 RGX SETUP

Once you access the web page, you should see the main page. Click on the Configure Site button.

8.1 RGX ETHERNET SETUP

To connection your RGX card up to the world wide web, you will need a high speed internet connection with a public static ip. You must get the following information from your internet provider to setup your RGX. Outside Static Public IP address. Subnet Mask Gateway IP DNS Server IP SMTP Server IP A email address for the RGX card. Once you get this information, you will need to set up a router, unless you are using a dsl mo-dem that already has a router built in. In either case you need to do some planning. First, is the RGX going on an existing network or on a network dedicated to just the RGX.



The IP address will typically be what we call an internal ip number. The default setting for the RGX is 192.168.1.50 with the HTTP port 80. The HTTP port 80 is a default port. If your com-puter is on the inside you could access the RGX with http://192.168.1.50 If you changed the HTTP port to 4005, the access address would be http://192.168.1.50:4005 When using port 80 you do not need to include the port number in the address. Port 80 is normally re-served and not recommended for use with the RGX. If using a router it is important to use the port forwarding feature to allow access to the RGX from the outside. The Subnet Mask should be 255.255.255.0 in most cases. If you are tying into a large local network the network administrator can give you the correct IP and subnet mask. The Gateway ip will be provided by the internet provider. The DNS Server ip will also be provided by the internet provider. When making changes, it is important that you make the change and then press the Submit button. Then you must press the Save Changes button.



Click on the User drop down to set up the security for the system. You have three security settings: View, Control and Configure. You should have only one username with the Config-ure security. You do not want the end user to have access to the Configure settings. To dis-able the username, click on the dropdown and choose N.

The Site Info drop down allows you to set a Name for the RGX. The panel # is used for the UDP communications and in most cases would be set to 1. You may have times when you are using the RGX with other devices on the same network and 1 is already taken. Choose a slave address that is not being used in those cases. The UDP Port is used for remote access using program such as Xmax and Xbase. Normally this would be set the same as the HTTP port number.

Use this screen to set the Date and Time on the rabbit clock calendar. The time is in a 24 hour format.

8.2 RGX SECURITY

8.3 RGX SITE INFO

8.4 RGX TIME CLOCK



The E-mail drop down allows you to configure the RGX for e-mail and text messaging. You will need the SMTP server name and a E-mail address for the RGX. You can enter up to four E-mail addresses to send alarms and reports to. For text messag-ing, see appendix A for an E-mail address for your cell phone.

Use this screen to set up the communications port. All communications are N81. The J6 Aux Port is used for BCS communications as found on the CR, ER and Galaxy devices. The Mod-bus server ID is when the RGX is acting as a Client and communicating with a device such as a Touch Screen. The J7 Main port can be used to communicate with MODBUS devices or a specific G55 device using BCS. Set the J7 Main port for the desired baud rate. J10 or J12 can be used as a modbus client interface and you need to select the baud rate. The P1 Mo-dem Port Baud rate is a dedicated RS-232 port using the RGX as a client. The Card Poll Rate is the time in seconds between updates. Do not go below three seconds.

The configuration file is rather complex in the initial setup and definition of the Card. Every-thing has to be exact and the Card Definition part of the file should be setup by factory per-sonal only. Initially each of the cards has a definition [CARD DEF 1]. After the card defini-tions is the actual setup file. These sections can be copied and pasted depending on the number of cards and the types. This first part of the [CARD DEF 1] is for the CR-110 card.
