5.4 Configuration Settings
5.4.1 Remote Unit ID
Each DCM-200 must have a unique ID number to allow the data collection software to
identify it. Legal six-digit values are 000000-FFFFFF (hexadecimal notation).
Sequential numbering is not required, nor is it necessary to use any of the hexadecimal
digits ‘A, B, C, D, E, or F’.
5.4.2 Destination
If the DCM-200 is allowed to originate a call to another modem (CSD mode), then it will
need the phone number of the modem. Select the “Phone Number” button and enter up
to 32 numeric digits, including the “#” and “*” symbols. It may be necessary to include
the area code even if the call is local. Check with you cellular provider.
If the DCM-200 is to communicate via the Internet (GPRS mode), then it will need the
address of the data collection server. Select the “IP Address” button. Then enter the
address of the server expressed in “dotted decimal format”, such as 198.32.67.101. The
administrator of the data collection system usually assigns this address. At this time the
DCM-200 is not able to use a domain name, such as www.metretek.com
.
The data collection server is assigned a default port number of 50465. This value is
displayed on the MP32 screen for reference only. This is the port number that will need
to be opened on the server. If this number is not acceptable then, while holding down
the CNTR key, double click on the Port Number box. This will unlock the box and allow
you to change the port number.
5.4.3 Originate Calls
Check this box if the DCM-200 is allowed to originate CSD calls or Internet connections.
5.4.4 Respond to Voice Calls
Check this box if the DCM-200 is allowed to answer CSD calls, or is allowed to be paged
using its voice phone number. See Chapter-7 for more information about paging.
5.4.5 Respond to SMS
Check this box if the DCM-200 is allowed to be paged via SMS (short message service).
See Chapter-7 for more information about paging.
5.4.6 Maintain Internet Connection
When the DCM-200 originates an Internet connection, it must request access to the
cellular provider’s GPRS service, then access to the Internet and finally access to the
destination server. All of this negotiation takes a certain amount of time. To reduce this
time the DCM-200 can maintain access to the Internet at all times and only needs to
request access to the destination server, which only takes a few seconds. This is often
referred to as an “always on” connection.
NOTE: To use this feature you must also check the Originate Calls checkbox. When
maintaining an Internet connection it is not possible to answer incoming phone calls or
SMS pages, so those selection boxes are disabled on the screen.
