Industrial Design
DAM-3028D was designed to use in industrial environment. It can be installed in standard DIN rail inside
the cabinet. And it can be powered by unregulated 10VDC ~30VDC to meet the various power supplied
source in field. It also withstands ambient temperature up to 60℃and resists the effects of vibration and
mechanical shock.
Wiring & Installation
Power supply requirements: unregulated +10VDC ~ +30 VDC. "+Vs" is a positive, and "GND" is ground.
"DATA +" and "DATA-" connect with "DATA +" and "DATA-"(or "A" and "B") of RS-232/RS-485
transformation module, then connect transformation module with computer, do not hot plug carefully.

The power indicator flashes after wiring is correct, then you can communication with the host computer.
According to the label directs color to wiring:
+Vs （R）Red DATA+ （Y）Yellow
GND（B）Black DATA- （G）Green

Wiring Application
Reset Connection:
Shorted the INIT * and GND shorted, add +10 ~ +30 VDC between +Vs and GND, power on, the module indicator
quickly flashes three times, power off until the indicator stops flashing, disconnect the INIT * and GND, then reset the
module has been completed.
After reset successfully, the module restore the factory default values:
Module Address: 1
Baud Rate: 9600
TTL/CMOS Signal Input
Open-collector Output

Default Setting
If the module’s address or baud rate is wrong, or forget the last modified value, the module can be reverted to default
settings. Steps: Short-circuit the “INIT*” and “GND” when there is no power; power-on for 3 seconds, power off,
disconnect “INIT*” and “GND”. The module is reverted to the default settings.
Address: 00
Baud Rate :9600bps
Noparity
The serial port default work mode: parity bit: none
data bits: 8
stop bit: 1
