All Digital IOs are 3.3 V LVTTL CMOS logic and can be used for data rates up to 20 Mbps.

* This is a +3.3 V supply that can provide up to 250 mA for external use.
The supply is protected against short to ground and keeps the current below 400mA in a continuous short.

** Can be configured as 5.0 V CMOS logic. Upon request only, please contact sales@synapticon.com

*** This is a +5 V supply that can provide up to 250 mA for external use.
The supply is protected against short to ground and keeps the current below 400mA in a continuous short.

Note

Each Digital IO needs to be configured as a Digital Input or Output via object 0x2210 (“GPIO”).
The object can also be used to activate a pull-down resistor.

Changes may require to powercycle the node.

Analog IN

Pin #   Default Setting *
1  
2 Analog Input 1 - Connect to Ground **
3 Analog Input 1 + Single-ended 0-10 V
4 Ground  
5 Analog Input 2 - Connect to Ground **
6 Analog Input 2 + Single-ended 0-10 V
7 5 V ***  
8 10 V ****  
9 Analog Input 3 - Differential ±5 V
10 Analog Input 3 + Differential ±5 V
11 Analog Input 4 - Differential ±5 V
12 Analog Input 4 + Differential ±5 V
* All Analog Inputs can be configured as single-ended 0-5 V, 0-10 V, 0-20 V or differential ±5 V, ±10 V independently.
Upon request only, please contact sales@synapticon.com

** Must be connected to Ground when the Analog Input is set to Single-Ended Mode.
It is recommended to use a separate ground cable for each single-ended analog signal/cable and twist or tie them together.

*** This is a 5 V supply that can provide up to 100 mA for external use.
The supply is protected against short to ground and keeps the current below 400mA in a continuous short.

**** This is a 10 V supply that can provide up to 25 mA for external use.
The supply is protected against short to ground and keeps the current below 100mA in a continuous short.
