AirShield Serial Converter: from RS-232 to RS-485
This small board converts the RS-232 signal of the AirShield Hub 2 to RS-485. This lets you connect equipment that only has an RS-485 connection to your alarm system.
The converter (Dahua ARA715) draws its power from the RS-232 port of the hub, so a separate adapter is not needed. An LED indicates that it is powered.
Why this converter
No separate power supply needed
Powered by the RS-232 port of the Hub 2, so no extra adapter or battery is needed.
RS-232 to RS-485
One RS-232 input and one RS-485 output, for equipment that only supports RS-485.
Compact and out of sight
Only 50 x 12,7 x 7,2 mm, so it disappears from view next to the hub.
Status indication
An LED shows that the converter is powered.
