8.2.5.3.1. Routing table size
Function - Defines size of routing table
Data type - number
Range - 1....255

value - 1
Comments - the length of routing table should not be shorter than number
of network nodes the module communicates with.
8.2.5.3.2. Routing table
Idx - index number of the list
number IP - IP address of GPRS network node
number ID - Modbus ID number (0-255) of slave device connected to GPRS
network node with given IP address
Comments - In basic configuration where replies are sent only to inquirer
the table may remain empty.
The table needs to be filled out when replies have to be sent to
other Masters.
Second column holds IP address of auxiliary master, while
third column - Modbus ID of device which answer has to be
sent additionally to auxiliary master. If third column has value
0 ( zero ), replies from all connected to module slaves and
module's internal resources will be sent to appointed IP

Sending replies to any number of Master devices is possible (
Multimaster mode ).
8.2.5.4. Modbus RTU Mirror mode
Modbus RTU Mirror is an extension of Modbus RTU Slave mode. The behavior of the
module is identical to Modbus RTU Slave mode seen from the GPRS point of view.
Remote access to internal module resources and to Slave devices connected to PORT 2 is
secured. An additional feature is the opportunity to map resources of slave devices
connected to PORT 2 into internal module registers. Upon activation of this option, the
module cyclically reads mapped areas and refreshes internal registers. Read more about
