8.2.5. Mode of operation
Group
Mode of operation
is not present on the list of parameter groups available for
MT-101 configuration.
It is only present in this manual in order to collect parameters accessible dependent on
selected operating Mode of operation.
In practice, only the group of parameters relevant for the selected mode will appear on the
list.
8.2.5.1. Transparent mode
MT-101 operating in Transparent mode sends all data received at PORT2 to IP addresses
appointed during configuration.
This is the standard operating mode employed as autonomic gateway between non-
intelligent device connected to serial port using not supported by MT-101 protocol.
8.2.5.1.1. GPRS transmission
In transparent mode, the module receiving data at serial port buffers it in internal
memory and converts it to data packet to be sent to defined recipients. During
packets creation, criteria described by variables of
GPRS transmission
sub group are
applied. Additionally, parameters allowing packet routing in order to reduce
transmitted data volume are defined.
Packet routing is possible only when the place where where the address identifying
final recipient in a disclosed mode is known.
8.2.5.1.1.1. Max. length of data packet
Function
- Defines (in bytes) maximal data volume in a packet. When
data volume in receiving buffer reaches declared size, packet
is sent.
Data type
- number
Range
- 1....1408
Default
value
256
Comments
- n/a
8.2.5.1.1.2. Data packet delimiter
Function
- Defines (in seconds) the time between received characters.
