Multi I/O-1 & I/O-2 - TELETRAC NAVMAN Qtanium 400 Installation Manual

4.8.3 Multi I/O-1 & I/O-2
Each Multi I/O can be configured in one of three different operating modes:

Digital Input

Digital Output

Analogue Input
Note When the satellite modem is enabled, Multi I/O-2 cannot be used.
Digital Input
When configured for Digital Input, Multi I/O-1 and Multi I/O-2 can only operate as Active
High Inputs, with the Active High functionality and wiring as described in section Error!
Reference source not found..
Digital Outputs
When configured for Digital Output, Multi I/O-1 and Multi I/O-2 operate as for the DO-1 and
DO-2 lines.
Analogue Inputs
When configured for Analogue Input, Multi I/O-1 and Multi I/O-2 connect to devices that
have a variable voltage output.
The input voltage range is 0–33 V DC. If the input voltage range exceeds 33 V DC, the input
must be scaled. To scale the voltage correctly, calculate the maximum sensor voltage to
scale to the max 33 V DC at the Analogue Input.
