•1 SIM card:
Ensure the card is enabled with data service and its service is not suspended
because of an overdue charge.
•Power supply:
5V/2A Type-C interface
Internal battery
•Fixation:
Please place CR202 on flat level and have it installed in an environment with small
vibrational frequency.
The device shall be installed and operated in powered-off status!
2.2 INSTALLATION
2.2.1 SIM/UIM Card
CR202 supports single nano SIM card or eSIM. Please install the SIM card like below if use nano

5
SIM card.
2.2.2Antenna
Slightly rotate the movable part of metal SMA-J interface until it cannot be rotated (at this time,
external thread of antenna cable cannot be seen). Do not forcibly screw the antenna by holding

6
black rubber lining.
2.2.3 Power Supply
CR202 supports internal battery or Type-C interface (5V/2A), please pay attention to the power
voltage level.
2.3 LOGIN ROUTER
Upon installation of hardware, be sure the Ethernet card has been mounted in the supervisory PC
prior to logging in the page of Web settings of the router.
I. AutomaticAcquisition of IPAddress (Recommended)
Please set the supervisory computer to "automatic acquisition of IP address" and "automatic
acquisition of DNS server address" (default configuration of computer system) to let the device
automatically assign IP address for supervisory computer.
II. Set a Static IPAddress
Set the IP address of supervisory PC (such as 192. 168. 2. 2) and LAN interface of device in same
network segment (initial IP address of LAN interface of device: 192. 168. 2. 1, subnet mask: 255.
255. 255. 0).

7
Automatic Acquisition of IPAddress (left) and Static IPAddress (right)
III. Cancel the Proxy Server

proxy service. The operating steps are shown below: 1) In the browser window, select
"tools>>Internet options"; 2) select "connection" page and click the button of LAN Settings to
enter "LAN Settings" window interface. Please confirm if the option "Use a Proxy Server for
LAN" is checked; if it is checked, please cancel and click the button <OK>.

(adm/123456 by default) in pop-up window and then access to router’s WEB management page. If
the browser alarms the connection is not private, show advanced, and proceed to access to the
address.
For security, please modify the default login password after the first login and keep the
password information.

3.2.2 WAN/LAN Switch
Click the “Network>>WAN/LAN Switch”to set WAN/LAN1 port.
When configure this port as WAN, CR202 supports three types of wired access including static IP,
dynamic address (DHCP) and ADSL (PPPoE) dialing. When configure this port as LAN, it
supports to jump to LAN configure page via Settings button on the right of the select box.
DHCP adopts Client/Server communication mode. Client sends configuration request to Server
which feeds back corresponding configuration information, including distributed IP address to the
Client to achieve the dynamic configuration of IP address and other information.
