forgot password or network IP address, serial console provide an easy way to access PAC-5070. To
access serial console port, you can use 91-0P9M9-001 to convert 10-pin header to RS-232 DB9 male
connector and use a null modem adaptor for PC RS-232 interface. Use any terminal software such as
hyper terminal and setting as follow:
Baud Rate: 115200
Data bits: 8
Parity: N
Stop bit: 1
Terminal type: ANSI
Once you power up PAC-5070, you will see the console message appears.

3.8 Power Input Connector (J3)
PAC-5070 uses +9VDC to 40VDC power and input from J3 connector. Auto-polarity and
surge protection are included in power input circuitry of PAC-5070 to provide power
protection to PAC-5070.
3.9 Digital Output Connector
The digital output are equipped with 8
darlington pair transistors (Allegro UDN2981A)
to switch the external relay or solenoid. The
internal transient-suppression diodes permit
the drive to be used with inductive load. The
source voltage of the drive is from 5Vdc to
40Vdc and the maximum driving current is
500mA.

To configure the IP address, Netmask and Gateway setting, please modify /disk/etc/rc as following:
ifconfig eth0 192.168.2.127 netmask 255.255.255.0
For DHCP setting:
dhcpcd eth1 &
3.15 Wireless LAN Configuration
PAC-5070 supports wireless LAN by using USB WLAN adaptor which uses Ralink RT2571 (rt73)
controller. Please refer to the website http://ralink.rapla.net for the supporting list of the USB WLAN
adaptor.
To configure the wireless LAN setting, please use command:
ifconfig wlan0 up
iwconfig wlan0 essid XXXX key YYYYYYYY mode MMMM
For infrastructure mode XXXX is the access point name and YYYYYYYY is the encryption key and
MMMM should be managed.
For Ad-Hoc mode mode XXXX is the PAC-5070 device name and YYYYYYYY is the encryption key
MMMM should be ad-hoc.
To configure the IP address use command:
dhcpcd wlan0 & or ifconfig wlan0 192.168.2.127 netmask 255.255.255.0
3.16 File System
PAC-5070 configures the root file system as RAMDISK and the user disk (/disk) which includes /home
and /etc directory are configured as Flash Disk. To find out the file system information, please use
command /mount as show as above. In addition, use command /df to find out the disk space of the
disk. The RAMDISK uses 8MB memory space to store the root file system and the user disk is about
11MB for user’s program storage.

4.5 How to Read Analog Input Data
To read the analog data of the input channel, please follow the steps below:
Set the configuration of the analog channels [adc0~adc3]
Repeatedly read data from the device [adc0~adc3]
Note
Please set the delay time to be 100ms or longer if you want to perform multiple channels scan. The ADC device
driver will delay 100ms for Multiplexer and Programmable Gain Amplifier to be stable before taking the data from
ADC.
