2.2.1 Power interface:
5.5*2.1 standard 5-18v power interface, with TVS protection
2.2.2 RS232 interface:
Device serial port is male(needle), RS232 level (can connect to PC directly), pin order is
consistent with PC COM port. Use cross cable connected with PC(2-3cross,7-8cross, 5-5
direct, 7-8 can disconnect, but MUST NOT connect with PC directly), There are 6 pins in work,
others is NC.

2 RXD Receive data pin
3 TXD Send data pin
5 GND Data Ground
7 RTS Request to send
8 CTS Clear to send
9 VCC Can connect to module power input by join the PCB jumper,
default not connect.
2.2.3 RS485 interface:
Rs485 two wire links, A(DATA+), B(DATA-), when link to other RS485 device, A(+) to A(+), B(-)
to B(-).
2.2.4 RJ45 interface:
Network port connection, module is 10M/100M adaptive, support AUTO MDI/MDIX, which
means you can use direct network cable to connect with PC also can be tested. Module by
default closed , need AT command set tings to open, as shown in the module specificatio n s.

2.2.5 Reload key:
This key used for set up the module to factory setting, when module is working (Ready LED
on), press this key more than 1 seconds and free it, wait about 10 seconds until the module
restart, the green LEDs all off and then Ready LED on. Then the module goes to factory
default settings.
