1. Forward
Thank you for your selection of Ethernet module EMA8308 analog input output interface.
Thanks to the booming of network, Ethernet become a reliable and low cost solution for data
communication. To utilize the Ethernet as data communication highway of industrial control devices is
more attractive than ever. EMA8308 module is a simple web based analog I/O control module. Standard
type EMA8308 and EMA8308D is 16 bit version. While EMA8308D are 8 channels differential input,
EMA8308 and are single or differential type. You can choose the suitable type for their application to
achieve maximum resolution/cost. We have provided the dll’s of Window’s or Linux system, enabling
you coding the flexible application as you need. Stable, high reliability and remote addressable module
give you a new approach of application.
In the same series:
EMA8308 24bit uni-polar 8 differential /16 single end analog input, 2 16bit analog output
EMA8308D 24bit bi-polar 8 differential analog input, 2 16bit analog output

7. System Reset
The system reset switch SW2 has provide normal system reset and reset to default functions.
7.1 Normal system reset
Push the SW2 for more than 5 seconds, the power LED will flick at 3 HZ to signal the system has
already reset. Once you release the switch, the LED will return to normal flick rate.
7.2 Reset to default
Push the switch while power on (We suggest to push the switch first then power on and wait for 3
seconds) for 3 seconds, the LED will:
1. stop flick
2. flicking at 3 Hz--- system now setting default data
3. flicking at normal speed --- system now already reset, you can release the switch.
