The T-port module can be positioned in the first or second optional module slot, see section Section 3.11,
“View of Radio Modem”. (Or only in the first slot for MG100 modems.) The second slot is recommended
because when using slot 1 you need to take into consideration the fact that it needs disconnecting
when the modem is in service mode. For more detailed information see section Section 3.10, “Service
Connector”.
T-port parameters are set up for communication with attached devices using a web browser. If the T-
port IP address is unknown it can be found using program DigiConf from Digi

.
Attached devices send TCP/UDP frames from which data packets are generated after unpacking in T-
port. Based on the format of these packets a suitable serial link protocol can be selected and they can
be configured on the SCC using Setr. The standard setting for configuration parameters is 9600, 8
N 1.
