Page 10: Hardware Installation
Raspberry Pi and Iono Pi board. Iono Pi The Iono Pi module comes pre-assembled with a Raspberry Pi 3 Model B or B+ board, in a plastic standard DIN-rail case. There is no need to open the case, unless you have to change the position of the jumpers that select the voltage level of the TTL/DI inputs (see below), or to replace the internal battery. - Page 11 The RTC backup battery holder is soldered to a small circuit board next to the GPIO connector. In the Iono Pi server, the battery is not accessible from the outside. You should first remove the case top body to gain access to the Iono Pi circuit board.

Page 13: Terminal Blocks
Terminal blocks Iono Pi has two terminal blocks. A 15 positions terminal block, used for power supply and low-power input/output connections. The maximum conductor cross section is 1.5 mm (16 AWG), or 0.5 mm when using ferrules (highly recommended). Recommended stripping length is 5 mm. Screw thread is M2. -
Page 14: Input/Output Mapping
Input/Output mapping The following table shows the mapping of the inputs and outputs of the Iono Pi module into the related pins of the Raspberry Pi board. These pins should not be used for other functions. Iono inputs and outputs... -
Page 15: Power Supply
Considering the amount of current needed to drive the relays and open collector outputs, it could provide up to 2.5A at 5V to the Raspberry Pi. Because Iono Pi has a 1.1A resettable fuse (polyfuse) on the power supply line, the maximum current that its regulator can deliver is also limited by this fuse, and depends on the input voltage. -
Page 16: Aix: Analog Inputs
WARNING The Iono Pi might be damaged if A-GND is not at the same voltage level of VS- and GND and any amount of current is allowed to flow through A-GND. Two additional inputs (AI3 and AI4) are available on an on-board expansion header (CN3) for custom extensions. -

TTL I/O or as the DATA0 line of a Wiegand interface. The TTL1 front-end circuit has a 4.7kOhm pull-up resistor. WARNING Never apply voltages outside the 0-5V range to this pin to avoid damage to the Iono Pi board and Raspberry Pi. TTLx/DIx: TTL input/output or generic digital inputs TTL2/DI1, TTL3/DI2 and TTL4/DI3 are dual-purpose pins. - Page 18 TTL LEVEL CONVERTER CIRCUIT AND INPUT MODE SELECTION JUMPERS TTL4/DI3, configured as TTL I/O, can be used as the DATA1 line of the second Wiegand interface, in combination with TTL3, or any other generic TTL I/O function. The TTL2-TTL4 front-end circuits have 4.7kOhm pull-up resistors. When these pins are configured as generic digital inputs, they are protected by a resistor network, and pulled to ground when not connected.

Page 19: Ocx/Dix: Open Collector Outputs Or Generic Digital Inputs
TTL4/DI3 WARNING Note that the Iono Pi board and the Raspberry Pi could be damaged if the jumpers are configured for TTL mode and voltages outside the 0÷5V range are applied to the inputs. OCx/DIx: Open collector outputs or generic digital inputs OC1/DI4, OC2/DI5 and OC3/DI6 can be used as open collector (OC) outputs or generic digital inputs. -

(when the Raspberry Pi is off). Depending on operating conditions it should last up to two years if the Iono Pi board is not powered, more if the Iono Pi receives external power. Once the RTC modules and configuration files are properly installed, you will simply use the date and time commands to control the hardware clock. -
Page 21: Software Installation And Configuration
Software installation and configuration All features of Iono Pi, except the real time clock and ADC converter, are controlled via dedicated GPIO pins and can be used with any operating system and programming language that supports the GPIO pins control on Raspberry Pi. The real time clock is interfaced via the I C serial bus, while the ADC uses the SPI lines. -
