There are several protocols supported by the AD2000 Series devices which have Master mode support. This mode is where the AD200 Series device port is initiating the data requests (i.e. the polling). This requires a station type icon to build the parcels between.
General
This section sets the general properties associated with the station for this type of device. Station Name
A text description can be used to label the station in the map e.g. PLC 1, VSD 44 etc. and this is displayed on the Map window and on any properties boxes for that station.
Identifier
The identifier is a unique number assigned to the station in the MiriMap2000+ configuration file. It is automatically assigned by the software but can be changed by the user (e.g. Station Name Pump 1 can be 1, Station Name Pump 52 can be 52) but must be unique and no greater than 2048. If an identifier is manually assigned and it is not unique a warning will be displayed, requiring the change to be repeated with a unique number.
The first station identifier is always assigned automatically to be 1 but it does not have to be 1, the user can choose a number scheme to suit their requirements. As new stations are added the automatically assigned number will be the next lowest number available.
For systems that have less than 100 stations assigned, it is recommended to assign the Other Protocol Type devices the identifier to be 101 and onwards, where the remotes between at 1-99. Thus any Other Protocol Type device connected to AD2000 Series device identifier ID=1 can be 101, AD2000 Series device identifier ID=10 can be 110 and so on to AD2000 Series device identifier ID=99 where the Other Protocol Type device can be 199.
The choice of identifier numbers has a significance because the identifier is used for selection of

Link Status/Poll Select bit 2 of block 1 relates to identifier 2
Link Status/Poll Select bit 16 of block 1 relates to identifier 16 Link Status/Poll Select bit 1 of block 2 relates to identifier 17
Link Status/Poll Select bit 1 of block 3 relates to identifier 33, and so on.
See Link/Poll Bits for further details on Link Status and Poll Select blocks.
For Other Protocol Type devices, ensure that the correct port is assigned for these Link/Poll bits to get the correct status points.
Type
The type setting determines what protocol the Other Protocol Type unit is using. The types supported will be displayed in the drop down box. In most cases this will be represented by the protocol that the device uses as in many cases the same protocol will suit multiple PLC type units and third party devices.
PLC Address
Most protocols support multi-drop addressing and this field allows the identifier number associated with that PLC address to be assigned. It is the address the parcels will be sent to across the physical link and thus must match the setting in the connected device (which has to be set via other software or user interface on that device. Consult the user manuals for the Other Protocol Type device).
Description
This is a text box where further details about the station can be added to give more information or to add notes or revision notes.
Phone Details
When using GSM or dialup enabled AD2000 Series devices, several phone number related parameters are available to allow connection to the Other Protocol Type device. These are only supported if these units support dialup type connections.
IDD Number
This is the International Direct Dialing for the country in which the AD2000 Series device is installed. It should only be set when the dialling is across international borders (e.g. 61– Australia, 60 - Malaysia, 1 - USA, 44 - UK, 64 - New Zealand etc. - consult your local white pages or telecommunications carrier for details on other countries).
Primary (Data) Number
The first phone number to dial. If the primary phone number only is defined (i.e. no secondary) then the retries (if specified) will repeat to that number.
For dialup systems when retries occur and a secondary number is specified each retry attempt will toggle between the primary and secondary numbers. For example, if the primary number is dialled and fails to connect the secondary number is dialled next. If that fails to connect then the retries are attempted. First there is a time delay (as specified in the Dial Again Time). For the first retry, the primary number is dialled again and if that fails the secondary is dialled again. This repeats until the number of retries has been exceeded. If continuous retries are selected then this toggling retries forever, until a connection is made. In the case of event parcels in such a scenario, the event buffer will overflow and further events will be lost. It is advised that continuous retries be used on point to point systems only.
