3311 adapter
3311 adapter is a RS232 to TTL leve converter. AR 3600/3700ís com port is a TTL level serial port. This adapter can connect 3600/3700 series products to any device equipped with RS232 interface
 
3312 adapter
3312 adapter is a USB to TTL leve serial port converter. AR 3600/3700ís communication interface is a TTL level serial port. This adapter can connect 3600/3700 series product to the USB port of PC.
 
3313 adapter
3313 adapter is a RS232 to RS 485 converter. It converts the RS232 signals to the RS485 differential signals A+/B-. This converter allows access to a multi-drop RS485 network or connection to a point-to-point RS485 device.
 
3314 adapter
3314 adapter is a RS485 to TTL leve converter. AR 3600/3700ís communication interface is a TTL level serial port. This converter can connect AR 3600/3700 to other devices which have the RS485 interface, and allows access to a multi-drop RS485 network or connection to a point-to-point RS485 device
