3.3 Installation

3.3.1 SIM/UIM Card

TD210 supports normal SIM/UIM only, so if you’re using a Micro SIM or Nano SIM card,

you may need to use a Micro SIM or Nano SIM to Normal SIM adapter.
Make sure your IP Modem is powered off, then use a needle object(such as a pen) to
push the button near the SIM/UIM card holder, it will flick out immediately. Put the
SIM/UIM card to card holder with chipset upside, insert it to IP Modem and make sure it’s
tightly matched.

Warning: Never install SIM/UIM card when Modem is powered on.

3.2.2 Cellular Antenna

Fasten the cellular antenna.

Screw the SMA male cellular antenna to TD210 (SMA female interface), make sure it is
screwed tightly to ensure the strength of signal.

it couldn’t connect to backup center, it will continue to connect to main center till it’s
connected.

 2-5 means TD210 supports multi centers, and all the other centers will get sync data.
Note: if there is not backup center, please set up the same address and port for main
center and backup center

2) Center Addr.+Port

It can be configured as DNS or IP address.

3) Center DNS Server

4.4.4 Heartbeat Interval

Heartbeat time, we suggest you set up 60 seconds for TCP, and 31 seconds for UDP.

4.4.5 Auto Back to Main Server

 Y
Auto back to main server.
 N

Don’t auto back to main server.
This setting will only work when both main and backup center are enabled, under this
work mode, if main center fails, TD210 will auto connect to backup center. If you choose

‘Y’, TD210 will check whether main center is recovery or not, if yes, it will switch to main
center, and disconnect with backup center. While if choose ‘N’, TD210 will not check

whether main center is recovery or not.

4.4.6 Custom Register String

You can configure it when network word mode is configure as CTCP and CUDP, but you
can also choose not to configure it, which means register string won’t be sent.
Note: the length of register string is up to 70 bytes.

4.4.7 Custom Heartbeat String

You can configure it when network word mode is configure as CTCP and CUDP, but you
can also choose not to configure it, which means register string won’t be sent.
Note: the length of register string is up to 70 bytes.

4.4.8 Transfer Meaning

 Y means Yes
 N means No

When network work mode configured as FTCP, if choose Y, then TD210 will transfer

meaning ‘0xfd’ to ‘0xfd’ and ‘0xfe’, and ‘0xfe’ to ‘0xfd’ and ‘0xee’. If choose N, it is

transparent transfer.

4.4.9 TCP MTU

Set up the maximum number of data transmission for each TCP data packet.

4.4.10 Multi Center Reconnect Interval

Only available when data center number is 2-5.

4.4.11 Reconnect

In real application, the data center may be shut down or have issue, and that will cause
TD210 disconnects from data center, while in order to keep TD210 always online, it will try
to reconnect the data center, and that will cause unnecessary data flow. So you can
configure those 2 functions to save the data flow, when Reconnect Time Interval enabled,
TD210 will try to reconnect data center, and if Connect Retry Times exceed the value you
set, while TD210 is still unable to reconnect to data center, TD210 will do exception
handling.

4.4.12 ECHO Heartbeat Interval

 0 means disables ECHO Heartbeat.
 1-65535 means heartbeat interval, 60 seconds is suggested.

This helps to maintain connection of PPP layer and mobile carrier’s network, to avoid
being forced to sleep, and helps to check the stability of connection.

4.4.13 TTL Heartbeat

 Disable, to disable TTL heartbeat
 Enable, to enable TTL heartbeat

This helps to maintain connection of Application layer and mobile carrier’s network, to

avoid being forced to sleep, and helps to check the stability of connection.
