Chapter Three
Configuration
Getting Started
Perform these steps;
1. Connect the EM00-GATE-0000 gateway to your computer’s Ethernet port using a cross-wired RJ45
cable or connect the EM00-GATE-0000 to a hub or network using a straight wired RJ45 Category 5
cable. The EM00-GATE-0000 is limited to a 10BaseT connection and will not work on an Ethernet
port set for 100BaseT only. Use of a 10/100 hub will overcome this issue if your PC has only a
100BaseT port.
2. Wire the temperature controllers to the gateway’s EIA-485 port. You may connect the gateway’s EIA-
232 port to a controller if you will be using only one controller, provided that the controller has an EIA-
232 port.
3. Wire a 24-volt AC or DC power supply to the gateway terminals. This is not polarity sensitive.
4. Configure each controller to the same baud rate (9600 or 19200) from the front panel of the
controller. Set each controller’s Modbus address to a unique number. As an example, set the first
controller to address 1, the second to address 2 and so on.
5. Power up the gateway, controllers and PC.
6. Start your Internet browser. Enter the TCP/IP address of the gateway into the browsers’ address field.
Two different addresses may be used to access the gateway. Either EMxxxxxx, where xxxxxx is the
first six digits of the serial number, or WATxxxxxx, where xxxxxx is the last six digits of the gateways’
MAC address. The MAC address is printed on a decal in the form xx:xx:xx:xx:xx:xx.
7. Select the Gateway Setup Page. Enter User name ‘new’ and Password ‘user’ by default. The
Password can be changed on the Security Configuration screen.
8. Configure the Baud Rate and range of controllers’ addresses to match those you configured in step
four.
9. Click on Rescan Modbus Network
10. Click on the back button of the browser to return to the previous page.
11. Click on the refresh button of the browser and your controllers’ information should now be visible.
Note:
You must click on the refresh button within the browser to capture the latest controller information.
This information is automatically refreshed after 10 seconds by default. You may change this refresh time
using the appropriate page.
Network Services
The EM00-GATE-0000 supports DHCP client, autoIP, and static IP for address assignment. Normally you
will not need to make any changes. The user is able to configure preferences as to which services are
used if available. Intelligence is employed within the gateway to revert to backup IP assignment methods
if the primary method is unavailable.
The gateway does support DNS client and Netbios name resolution. Configuration information may be
entered at the EM Gateway Network Display Setup page.
Email Alarm Notification
The email function allows the user to send emails to four addresses alerting them of alarm conditions that
have occurred on the controllers connected to the Gateway. A button on the Graphical User Interface
(GUI) allows the user to enable or disable this feature. Emails can be generated whenever an alarm
condition occurs for each controller. An email acknowledge feature requires that the user acknowledge
the email message by operating the email acknowledge button before additional email alarm messages
can be generated for that controller. For multiloop controllers only one email acknowledge feature is
supported; if more than one loop produces an alarm, only the first alarm detected will generate an email
until acknowledged.
