nextReaderIdHi is the upper two bytes of the next Reader MAC address.
Returns
0 - Success
Less than zero – No Reader higher than current Reader (current Reader is the last Reader in the group).

public virtual int RemoveGroupEntry( int groupId,
int readerIdLow ,
int readerIdHigh)
This function removes a Reader from a group. The Reader entry must exist or an error is returned.
groupId is the ID for the group.
readerIdLow lower four bytes of the Reader MAC address.
readerIdHi upper two bytes of the Reader MAC address.

4.5.2.6 Map Configuration
These functions allow configuration of the Location Software’s internal database of Maps.
4.5.2.6.1 AddOrUpdateMapParms Function
public virtual int AddOrUpdateMapParms( int mapIndex,
int flags,
double snapDist,
int bufferSize,
double * trackingCellPoints)
This function sets the parameters for a map. A map can have a tracking cell which is a polygon boundary limiting
where Tag positions can be computed. If the map parameters already exist, they are updated.
mapIndex is the ID for the map. Must be greater or equal to zero.
flags is a bit field that controls the group characteristics
Bit 0 - Map Tracking Cell is enabled
snapDist is used to control the “snap to” feature. If a position is outside the tracking cell, the distance to the
nearest point on the tracking cell boundary is computed. If that distance is less than this value, the position is
