The inputs can be powered using the VS signal on the scanner (pin 9).
However, isolation between the command logic and the scanner is maintained by powering
the inputs with a different supply voltage (Vext) from that supplied on pin 9 of the
25-pin/26-pin I/O connector.
The driving logic of the input signals may be powered, for convenience, with the voltage
supply between pins A (VS) and B (GND) of the connector. In this case, however, the device
is no longer electrically isolated.
The voltage available on the input connector, between pins A and B, is physically the same
as used to power the scanner.
The electrical features of these inputs are:
Maximum voltage 30 V
Maximum current 10 mA
Outputs
Three general purpose outputs are available.
Pin Name Function
8 OUT 1+ Configurable digital output 1 – positive pin
22 OUT 1- Configurable digital output 1 – negative pin
11 OUT 2+ Configurable digital output 2 – positive pin
12 OUT 2- Configurable digital output 2 – negative pin
16 OUT 3A Configurable digital output 3 – polarity insensitive
17 OUT 3B Configurable digital output 3 – polarity insensitive
The function of the three outputs OUT1, OUT2 and OUT3 can be defined by the user.
Refer to Genius™ Help On-Line for further details.
By default, OUT1 is associated with COMPLETE READ event, which activates when the code
has been read correctly. In case the reader has been programmed to read several codes
within the same reading phase, the event activates when all codes have been read.
OUT2 is associated with NO READ event, which activates when no code has been read.
OUT3 is associated with NONE, which means that the output is always in line state.
The OUT1 and OUT2 electrical features are given below:
Collector-emitter voltage 30 V Max.
Collector current 130 mA Max.
Saturation voltage (VCE) 1 V at 10 mA Max.
Maximum power dissipation 90 mW at 50°C (Ambient temperature).
The limit requested by the maximum power dissipation is more important than that of the
maximum collector current: if one of these outputs is continuously driven, the maximum
current must not be more than 40 mA although 130 mA may be reached in pulse conditions.
