2Device Overview
T61 is a smart gateway connecting serial devices with RS232 or RS485 interfaces to
GSM/GPRS/HSPA/LTE network. It is integrated with a 32bit ARM Cortex-M0+ core processor and a
Gemalto 3G or 4G modem module. Equipped with comprehensive features, T61 smart gateway
provides industrial standard flexibility, scalability and data reliability.
T61 Smart Modem has two operation modes, namely Normal Modem Mode and Smart Modem
Mode. In Normal Modem Mode, T61 functions as a standard 3G or 4G modem by providing a direct
serial access to a Gemalto EHS5 or ELS61 module. User could send AT command to achieve various
functions, such as SMS, GSM/GPRS/3G/4G connections for data transfer. In Smart Modem Mode,
T61 provides a transparent channel from remote end devices to their dedicated data centers. It can
be configured as server or client, accept SIM card with dynamic IP or static IP, support TCP/UDP,
schedule to connect, connect on demand or “always on” connection, and with Auto Recovery, Re-
connection and Redundancy mechanisms.
As compare to PSTN or GSM dial up line or lease line, T61 smart gateway allows you to migrate your
remote device from traditional serial communication system to the advance GPRS or 3G/ 4G link,
without tedious application development or in depth knowledge of AT command or GPRS/ 3G/ 4G.
You can view this device as the “virtual serial wire over the air”, that links all your remote equipment
to the central PC. It can be a full transparent, protocol independent gateway, used for AMR, SCADA,
general remote monitoring, control and data exchange applications. It is designed for mission critical
industrial applications.
Two operation modes:
Normal Modem: The Data Terminal Equipment (DTE, such as PC, PLC, energy meters,
controller etc.) is intelligent and can issue various AT commands to T61 normal modem as
DCE (Data Communication Equipment) to establish SMS send /receive, GSM/GPRS/HSPA/LTE
dial up connection etc.
Smart Modem: In this mode, T61 Smart Modem can be configured with all essential
parameters to manage connections. It connects to assigned data centre server automatically
upon power up and sets up a transparent serial-to-wireless communication channel
between remote devices and data centre. During operation, T61 Smart Modem can maintain
the wireless connection and re-establish connection to data centre server in case of
connection lost. It can monitor site conditions or connections status, such as signal strength,
online/offline etc. It shall be an easy retro-fit solution for existing wired system to 3G/ 4G
mission critical wireless system.

3Special Features
In this section, some of the new features of T61 Smart Modem are discussed in detail. This is for
better understanding of the device operation in smart modem mode. If your device is utilized in
normal modem mode, please skip this section.
3.1 Dual IP Connection
T61 Smart Modem provides two connection channels for easy handling of data and commands. One
channel is dedicated for data transfer and the other one process all control commands from
command centre or even authorized user mobile devices. This is realized by setting up two internet
connections, Data Line Connection (TCP/UDP) and Command Line Connection (TCP) (shown in Figure
2 below).
Data Line Connection: Transparent/User Defined data transfer channel. It is used for
obtaining raw data from remote devices.
Command Line Connection: Receive and process control commands. It can be used to
obtain device status, like signal strength, device ID, connection status and device current IP
etc. This connection is also used for GPRS configuration, and (firmware over-the-air) FOTA
when necessary.
These two connections can share a single server IP with different port numbers or they can be
connected to two different server IPs. Connections are set up automatically by the device. The idea
is to protect the integrity of user data with minimal interference from control commands. In the case
where command line connection is not needed, it can be simply disabled. The internet protocol for
data line connection can be customized as TCP or UDP but the internet protocol for command line
connection is always fixed as TCP.
Figure 2: Dual IP Connection
3.2 Self-Recovery
T61 Smart Gateway has built in recovery features to cater connection lost scenario. However these
features are only applicable when T61 Smart Gateway is set into smart modem mode and as a TCP
Client. Simply speaking, the device will restart itself when the server is no longer accessible. Please
pay attention to the following points regarding this recovery features.
GPRS/3G/4G
GPRS/3G/4G
RS232/*RS485

T61 Smart Modem Page 11 of 47
User Guide V1.4
Data Line Connection has higher priority. This setting is to safe guard the integrity of user
data communication. Once the device detect the data center is not accessible, it will restart
itself and try to reconnect back to the data center. In the meantime, command line
connection will break due to the reset.
Self-recovery will take effect immediately if connection lost is due to closing Center Manager
or losing GSM/GPRS/3G signal. It may take longer time if the connection lost is due to
abnormal sever shut down (i.e. connection is not properly closed).
3.3 DDNS IP Update
In order to connect the remote device to data server, IP address of data server is needed. This
becomes an issue when IP address is dynamic and changes over time. Dynamic Domain Name Sever
IP Update is implemented in T61 Smart Modem to resolve this issue. A domain name is used instead
of IP address. This is demonstrated in Figure 3.
When there is a change in IP address, server will update the new IP to our Domain Name Server so
that this new IP will be mapped to the domain name configured inside the device. Therefore, even
though the IP address is dynamic, device is always able to connect the correct IP using domain name.

7Device Configuration
T61 Smart Modem is robust and comprehensive. Most of its properties are configurable to cater
different requirements. In this chapter, all configuration options will be discussed.
There are two ways to configure T61 Smart Modem. One way is using TMAS Center Manager
software (Refer to the Center Manager User Guide). The other way is to use serial terminal software.
And terminal software will do the job, while HyperTerminal and Hercules are recommended. A
configuration menu is embedded inside T61 smart gateway. User can easily configure the device via
serial port. In this chapter, we will focus on the serial port configuration method. All screenshots are
taken using HyperTerminal.
7.1 Initial Setup
To configure T61 smart gateway, serial terminal software should be configured as followed:
Baud Rate: 115200bps
Data Bits: 8
Parity Bit: None
Flow Control: None
The factory default operation mode of T61 smart gateway is Normal Modem Mode, switch to Smart
Modem Mode before you continue. After powering up the device, you will see the start-up menu
shown in Figure 8. This start-up menu includes device mode, firmware version and product serial
number.
