Mapping Instructions
DC 12V
12V
To connect digital output devices, map the
DO device wires to the following:
DO1 and 12V
DO2 and 12V
Digital Output 1
DO1
Digital Output 2
DO2
In case of connecting more than one DI device, the GND pin can be commonly
shared by all four DI devices.
In case of connecting two DO devices, the 12V pin can be commonly shared by
the two DO devices.
Typical Connection
The table below shows the DI/DO connection specifications:
Device
DI
Connection design
TTL - compatible logic levels
Voltage
To trigger (low)
Logic level 0: 0V ~ 0.4V
Normal (high)
Logic level 1: 3.1V ~ 30V
Current
10mA ~ 100mA
DO
Connection design
Transistor (Open Collector)
Voltage & Current
< 24V DC, < 50mA
Based on these specifications, if the DI device has a voltage of 0V ~ 30V or the DO device
has a voltage of < 24V (< 50mA), then the camera can supply internal power to these
devices and there is no need to connect the DI/DO device to an external power source.
In this case, use the GND and the DI1 cables to connect a DI device and use the 12V and
the DO1 cables to connect a DO device. See wiring scheme below:
