The purpose of this device is to provide customers the possibility of monitoring the gensets operation
status through a database continuously updated by the devices via mobile GRPS phone line.
In addition, it allows localizing the machine via the GPS positioning system.
Moreover, you may configure the device for sending/receiving signal and control SMS and e-mails.
Furthermore, using a PSTN or GSM modem and the program SICES SUPERVISOR installed on a
PC, you can directly connect to REWIND and use it as a GSM modem. Simply install on REWIND a
SIM card enabled with the GSM DATA number.
Each device can be interfaced to all SICES controllers, as well as other manufacturers controllers
through a RS232 or RS485 serial port via Modbus RTU protocol.
The connection through serial line allows to acquire different statuses and operating measurements
of the genset. In addition, there are eight digital inputs for the acquisition of statuses and commands
and two relay outputs with dry contact.
REWIND communicates with the system either periodically or on event, so that all the existing
machinery database is updated.
This operation requires a SIM board enabled for data exchange, and a GSM/GPS antennas (even
integrated) with SMA male connector.
The device works in the same way with both 12 and 24Vdc as nominal voltage, in any case between
8 and 32 Vdc; as option, it can be supplied with a Lithium Ion internal rechargeable battery, which is
able to ensure its working, data transmission and localization for some hours in case of lack of the
main supply.
The device is able to automatically enter a Sleep Mode status in order to further decrease its
consumptions and increase its operating time.
Additionally, there is a dedicate input available for the connection of another external backup
rechargeable battery (max. 6Ah Lead battery). This battery works in case of lack of the REWIND
supply or when the supply decreases under the external backup battery.
A cladding system allows to keep this backup battery always ready to use.
The nominal voltage of the external backup battery must be equal to the supply nominal voltage.

The device is set with a non-insulated digital input that ca be activated with a connection to the
Rewind supply negative (J1-3 GND)
In the future FW revisions, this input will be available to be used to wake up Rewind from the
Sleep Mode, with an external electrical signal that can be acknowledged even in case of no
battery voltage.
Indeed, in case of no external battery voltage, the Rewind opto-insulated digital inputs may not
work.
Rewind, supplied by the sole Lithium Ion internal battery (optional), would be able to wake up by
means of this input and exit the Sleep Mode.
The device is equipped with a non-insulated RS485 interface. On terminal 7 and 6 of J2, connect
the signal A (Noninverting Receiver Input A/Driver Output A) and the signal B (Noninverting
Receiver Input B/Driver Output B) of RS485.
Connect the devices on the data line, avoiding star connections; ensure that the first and last
device on the line have a 120 ohm termination resistor. In case REWIND is the first or last device,
ensure to connect a 120 ohm 1/2 W resistor on terminals 6 and 7 of J2.
This electrical connection also requires a 120 ohm shielded cable.
The default serial port is set as: Modbus RTU Master, 9600,N,8,1.
The use of this serial line is allowed only for the devices of the same control panel or, alternatively,
for devices that are not subject to external overvoltage and supplied by the same DC supply
power of Rewind.
WARNING! Otherwise, you must carry out proper precautions, such as the galvanic
insulation of the signal with capacity of at least 1kV.
WARNING! Only one Master port can be selected. By the parameter “P.1101 Master serial
port”, it is possible to select the ports COM1 (RS232) or COM2 (RS485).

18 REWIND User’s Manual
In order to connect directly a PC or another RS232 equipment to the devices, you need to use a
crossover cable CANON 9 poles female on both terminals, as the following connection diagram:
Alternatively, it is possible to use a Crossover cable available with the following SICES code
E090000000048 CROSS OVER RS232 DB9P F/F MT2 AT CABLE.
•USB2.0 Port for the connection with PC
•Mini-USB B type connector
•Max distance 6m (20 feet)
Rewind is equipped with a USB 2.0 Function port (Slave).
The specifications of the USB protocol do not allow its use in permanent industrial field, because of
the limited cable length and the high sensibility to electrical disturbances also on the PC. For this
reason, the USB connection cable has to be inserted only when it is necessary to work on the
device and it has to be removed from the connector when the operation is over.
For the USB connection, it is necessary to use a cable USB-A male/USB Mini-B male.
The connection through the USB line with a PC is used for two purposes:
- Insertion of the device firmware
- Parameters programming

REWIND User’s Manual 19
The insertion/replacement of the device firmware is a specific SICES Srl operation; besides the
operating FW to insert, it requires a particular procedure and proper programs and usually it must
not be carried out by the installer, except for specific cases in agreement with SICES.
The USB port can be used for the parameters programming with the program BoardPrg3, as
alternative to the RS232/RS485 serial connection or Ethernet.
It is necessary to install the driver CDC_Sices_Win.inf supplied by SICES on the PC; for the driver
installation, refer to document [5].
Once the driver is installed, the PC will acknowledge the REWIND device as a new serial port, which
has to be used exactly as a RS232 serial port.
•RF SMA male Connectors
