WARNINGS about isochronous mode:

As a result there is a limitation to the number of ADSL StarModem which you can connect to the same USB 1.1 OHCI/UHCI controller, as well as combination of StarModem with GSM-BOX and UMTS-BOX/BOX2, for example:

Dimensions: 234x163x45;

Weight: 1.20Kg;

Power is provided both via USB to HUB, CODEC and PIC and with the additional power cable to SimCom modules. SimCom modules absorpt some current from the USB anyway, because of an internal -USB-powered- USB-to-serial converter interface chip.

The front panel contains the trimmers for the volume regulation, the doorphone interface connectors and the I/O connectors.

The trimmers allow to regulate the volume of the microphone and the speaker (clockwise: rise the volume, counterclockwise: lower the volume).

The following picture shows the trimmers and the connector pinout.

Figure 2.42. Citobox trimmers and pinout

Each doorphone interface contains two relays, RA and RB, whose "normally close" pins are closed and "normally open" pins are open when there is no active communication on the interface (default state).

The digital inputs are general purpose, so they can be used to connect any kind of hardware (additional ring buttons, digital sensors, etc.). Refer to Section 13.3, “CTI port configuration” to have more information about their configuration.

The digital outputs can drive any kind of device, accordingly with the electrical specifications.

The digital outputs are relay-based and have 3 volt free contacts (i.e. dry contacts, i.e. clean contacts): common, normally open and normally closed.

The OUT_NO is the normally open pin. When the DIG_OUT is set to 0, OUT_COM and OUT_NO are disconnected, while when DIG_OUT is set to 1 they are short-circuited.

The OUT_NC is the normally closed pin. When the DIG_OUT is set to 0, OUT_COM and OUT_NC are short-circuited, while when DIG_OUT is set to 1 they are disconnected.

	Warning
	Output relays support: a maximum switching current of 1 A (the moment when the relay is turned into CLOSED); a maximum carrying current of 2 A (during normal operation, stable CLOSED); DC voltage max. 220 V, AC voltage max. 250 V.

The CITO-BOX is composed by two parts: the CITO part and the IO part. They are managed by two separated PIC microcontrollers: the CITO-PIC and the IO-PIC.

The CITO part offers two completely separated interfaces for doorphones. The IO part offers 8 digital inputs, 4 digital outputs (clean contacts) and two analog inputs (available only if an analog adaptation module is present).

Each interface of the CITO part is mainly composed of 4 analog pins: SPKR, MIC, GND, CALL, which must be connected respectively to the speaker, microphone, ground and call button signals of the doorphone.

When a continuous or alternate voltage (voltange range 2.5V - 12V, frequency range: 0Hz - 100Hz) is applied to the CALL pin, the CITOBOX informs the Abilis, which activates the voice communication on the corresponding interface. The status of the relays RA and RB follows the one of the communication. RA_NC and RB_NC are closed when the communication is inactive and open when the communication is inactive, being the status of no communication the "normal" status. RA_NO and RB_NO follow the opposite behaviour.

The volume of the microphone and the speaker can be manually regulated with the corresponding trimmers, all of which are externally accessible on the front. The speaker and the microphone are decoupled by a transformer.

Each digital output of the IO part is a volt free contact (clean contact) and can be driven separately by the Abilis. Each output is available both as normally closed and normally open. It supports a maximum switching current of 1 A (transition current during the relay closure), a maximum carrying current of 2 A (after the relay closure, when the relay is stable), 220V DC max. voltage and 250V AC max. voltage.

Each input of the IO part is separated. It can be configured as clean contact input (default) or optoisolated input (use voltages in the range 5V - 12V). Each input can be manually configured through its corresponding couple of jumpers.

Figure 2.44. Citobox - Block scheme

Jumpers configuration allows to choose between clean contact and opto-isolated digital inputs. Jumpers configuration is available only in PCB Ver. 1.1.The PCB version is reported on the case label. PCB version 1.0 does not allow the configuration of digital inputs. Its digital inputs are only compatible with volt free outputs (clean contacts).

The SIMBOX-32 is composed of two boards: the master board and the slave board. the SIMBOX-16 is composed of the master board. Each board allows to plug up to 16 sim cards.

Communication between FPGA and PIC is implemented on the PIC's Streaming Parallel Port (SPP) peripheral. This port provides a fast 8-bit bus, where it is possible to connect more slave peripherals.

The RJ Switch is equipped with a PIC microcontroller which controls 8 onboard switches using the control lines. It is installed on the board and it's able to switch each LINE port to the correspondent main port or backup port.

This board contains a watchdog which must be driven by the main Abilis via USB; when the main Abilis stops sending LIVE signals to the board, the PIC understands that the main Abilis is failing and switches the line to the backup Abilis. The board's switch core/watchdog is based on a Microchip PIC18F2450.
