2 Interface Characteristics
EMS31-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 Serial Interface ASC0
EMS31-US offers an 8-wire unbalanced, asynchronous modem interface ASC0 conforming to
ITU-T V.28 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).
EMS31-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 2: 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 1,200bps up to 3,686,400bps.
• Autobauding (supported by future firmware version)
• Supports RTS0/CTS0 hardware flow control. Communication is possible by using only RXD
and TXD lines, if RTS0 is pulled low.

2.1.2 Serial Interface ASC1
EMS31-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).
EMS31-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 3: 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 1,200 bps to 3,686,400bps.
• Supports RTS1/CTS1 hardware flow control. Communication is possible by using only RXD
and TXD lines, if RTS1 is pulled low.
