2 Interface Characteristics
ELS31-US/ELS51-US is equipped with an SMT application interface that connects to the ex­ternal application. The SMT application interface incorporates the various application interfac­es as well as the RF antenna interfaces.

2.1 Application Interface

2.1.1 USB Interface

ELS31-US/ELS51-US supports a USB 2.0 High Speed (480Mbit/s) device interface that is Full Speed (12Mbit/s) compliant. The USB interface is primarily intended for use as command and data interface and for downloading firmware.
The V
line is used for cable detection only, this is to be supplied by the external device. The
USB
USB circuitry in the ELS31-US/ELS51-US is designed to meet the USB 2.0 specification for
1
self-power.2.0”
.
To properly connect the module's USB interface to the external application, a USB 2.0 compat­ible connector and cable or hardware design is required. Furthermore, the USB modem driver distributed with ELS31-US/ELS51-US needs to be installed.

2.1.2 Serial Interface ASC0

ELS31-US/ELS51-US offers an 8-wire unbalanced, asynchronous modem interface ASC0 conforming to ITU-T V.24 protocol DCE signalling. The electrical characteristics do not comply with ITU-T V.28. The significant levels are 0V (for low data bit or active state) and 1.8V (for high data bit or inactive state).
ELS31-US/ELS51-US is designed for use as a DCE. Based on the conventions for DCE-DTE connections it communicates with the customer application (DTE) using the following signals:
• Port TXD @ application sends data to the module’s TXD0 signal line
• Port RXD @ application receives data from the module’s RXD0 signal line
Figure 3: Serial interface ASC0
Features:
• Includes the data lines TXD0 and RXD0, the status lines RTS0 and CTS0 and, in addition, the modem control lines DTR0, DSR0, DCD0 and RING0.
• Configured for 8 data bits, no parity and 1 stop bit.
• ASC0 can be operated at fixed bit rates from 4800bps up to 921600bps.
• Supports RTS0/CTS0 hardware flow control. Communication is possible by using only RXD and TXD lines, if RTS0 is pulled low.
• Wake up from SLEEP mode by RTS0 activation.
The ASC0 interface is dedicated to signaling via AT commands (3GPP standard 27.007 + mod­ule specific AT commands).

2.1.3 Serial Interface ASC1

ELS31-US/ELS51-US provides a 4-wire unbalanced, asynchronous modem interface ASC1 conforming to ITU-T V.24 protocol DCE signaling. The electrical characteristics do not comply with ITU-T V.28. The significant levels are 0V (for low data bit or active state) and 1.8V (for high data bit or inactive state).
The ASC1 interface lines are originally available as GPIO lines. If configured as ASC1 lines, the GPIO lines are assigned as follows: GPIO16 --> RXD1, GPIO17 --> TXD1, GPIO18 --> RTS1 and GPIO19 --> CTS1. Configuration is done by AT command (see [1]: AT^SCFG). The configuration is non-volatile and becomes active after a module restart.
ELS51-US is designed for use as a DCE. Based on the conventions for DCE-DTE connections it communicates with the customer application (DTE) using the following signals:
• Port TXD @ application sends data to module’s TXD1 signal line
• Port RXD @ application receives data from the module’s RXD1 signal line
Figure 4: Serial interface ASC1
Features
• Includes only the data lines TXD1 and RXD1 plus RTS1 and CTS1 for hardware hand­shake.
• On ASC1 no RING line is available.
• Configured for 8 data bits, no parity and 1 or 2 stop bits.
• ASC1 can be operated at fixed bit rates from 4800 bps to 921600 bps.
• Supports RTS1/CTS1 hardware flow control. Communication is possible by using only RXD and TXD lines, if RTS1 is pulled low.
• Wake up from SLEEP mode by RTS0 activation.
AT commands for signaling are not supported on ASC1 interface. ASC1 is intended only for data transfer in a Linux environment.

2.1.4 UICC/SIM/USIM Interface

ELS31-US/ELS51-US has an integrated UICC/SIM/USIM interface compatible with the 3GPP
31.102 and ETSI 102 221. This is wired to the host interface in order to be connected to an
external SIM card holder. Five pads on the SMT application interface are reserved for the SIM interface.
The UICC/SIM/USIM interface supports 3V and 1.8V SIM cards.
The CCIN signal serves to detect whether a tray (with SIM card) is present in the card holder. The CCIN signal must be connected to V180 for the detection to work on the module. Other­wise the SIM card can never be detected by the module.
Using the CCIN signal is mandatory for compliance with the GSM 11.11 recommendation if the mechanical design of the host application allows the user to remove the SIM card during oper­ation. To take advantage of this feature, an appropriate SIM card detect switch is required on the card holder. For example, this is true for the model supplied by Molex, which has been test­ed to operate with ELS31-US/ELS51-US and is part of the Gemalto M2M reference equipment submitted for type approval. See Section 7.1 for Molex ordering numbers.
Table 1: Signals of the SIM interface (SMT application interface)
Signal Description
GND Separate ground connection for SIM card to improve EMC.
CCCLK Chipcard clock
CCVCC SIM supply voltage.
CCIO Serial data line, input and output.
CCRST Chipcard reset
CCIN Input on the baseband processor for detecting a SIM card tray in the holder. If the SIM is
removed during operation the SIM interface is shut down immediately to prevent destruc­tion of the SIM. The CCIN signal is by default low and will change to high level if a SIM card is inserted. The CCIN signal is mandatory for applications that allow the user to remove the SIM card during operation. The CCIN signal is solely intended for use with a SIM card. It must not be used for any other purposes. Failure to comply with this requirement may invalidate the type approval of ELS31-US/ELS51-US.
Note: No guarantee can be given, nor any liability accepted, if loss of data is encountered after removing the SIM card during operation. Also, no guarantee can be given for properly initializ­ing any SIM card that the user inserts after having removed the SIM card during operation. In this case, the application must restart ELS31-US/ELS51-US.
