5-6
5.4.7 Answer Ring Count
This field is always disabled. If the DCM-200 has been configured to respond to voice
calls it always answers on the first or second ring.
5.4.8 Time Interval Size
This setting is used in other applications and currently has no effect when interfacing to
an electric meter. However, this value is reported to the DC-2000 data collection
software, and DC-2000 will compare it to a value that it has in its database. If the two
do not match, the call will be rejected. Therefore it is recommended that both values
(here and in DC-2000) be set to 60 minutes. Chapter-6 has more information about DC-
2000
5.4.9 Firmware Version
The firmware version is updated on the screen whenever a ‘Read’ operation is
performed. This is not a parameter that can be changed. A value of “21” relates to a
firmware version number of 2.1.
5.4.10 Primary Call Retry Rate
If the DCM-200 is programmed to originate a call, and the call is unsuccessful for any
reason, it will try again at a later time. The DCM-200 will wait from 2 to 15 minutes
between each attempt. See Chapter-7 for further information about call retries.
5.4.11 Primary Call Retry Count
This is the number of times the DCM-200 will try to repeat a call at the “Primary Call
Retry Rate”, discussed previously. After this, calls will be attempted at the “Secondary
Call Retry Rate”, discussed next. See Chapter-7 for further information about call retries.
5.4.12 Secondary Call Retry Interval
After the “Primary Call Retry Count” has expired, the “Secondary Call Retry Interval”
defines the time between each additional attempt, in 1-hour increments. There is no
limit to the number of times the DCM-200 will attempt to place a call at this rate. Once a
call is successful, the DCM-200 will return to using the primary rate and count. See
Chapter-7 for further information about call retries.
The next configuration items appear on the Cellular Settings tab, which is shown back in
Figure 5-4.
5.4.13 PIN Number
Some SIM cards will accept a personal identification number (PIN) as an extra security
measure to prevent unauthorized use of the cellular account. The PIN number will be
from 1 to 8 numeric digits long. If a PIN number is not used, leave this field blank.
5.4.14 Service Type
The DCM-200 is currently configured to support only GSM cellular technology. Select
GSM before selecting the frequency band.
5.4.15 Frequency
Depending upon the service provider chosen and the region of the world in which the
DCM-200 is located, there will be a specific frequency band used for the cellular service.
These are generally 850 or 1900 MHz in North America, and 900 or 1800 MHz
elsewhere. Contact your service provider for more information. This setting is only
