1. OVERVIEW The modem is a rugged, full duplex Data and SMS modem designed to operate on 3G 850MHz networks. 3G is an efficient and secure cellular wireless technology that compliments fixed or mobile applications. The modem incorporates RS-232 and USB drivers, AC/DC down converter. The modem connects directly to a HOST computer utilizing a RS-232C or USB V1.1 interface. The Host signals are converted to the RS-232C or USB 1.1 signal levels.
1.2. Terms The following terms are used throughout this document. We have provided and explanation of these for your reference. Table 1-1 Term Description <> Field. Contents between ‘<’ and ‘>’ indicate the name of the field or the parameter required to complete the syntax. Delimiter/Space. Insert a space. AT command set Communications command set interface between data terminal equipment (DTE) and data circuit terminating equipment (DCE). BS Base Station.
Term Description PSTN Public Switched Telephone Network refers primarily to the telephone system based on copper wires carrying voice, fax & data. RCE Remote Customer Equipment. Describes the MT2, Rm and TE2 as one composite system. Rm Hardwire Interface between MT2 and TE2. SMS Short text Message Service. TE2 Terminal Equipment 2. A TE2 is a data terminal device that has a nonISDN user-network interface, e.g., CCITT V series or CCITT X series. Same as DTE.
2. AT INTERFACE DESCRIPTION 2.1. Basic Integration The modem supports asynchronous serial communication known as RS-232. This chapter describes the basic integration and communication of MT2 with TE2. MT2 hereby defines and TE2 means host products which can issue AT commands and handle the response through UART or RS-232 signalling. The popular examples of TE2 are PC’s, PDA’s and unmanned systems such as Data Loggers, RTU’s or PLC’s. 2.2.
2.3. Command Format The AT command set in UART1 is based on ASCII text. The extended AT command set by Qualcomm start with “AT$QC” and the extended AT command set by Maxon Australia start with “AT$$”. All commands should finish by , 0x0d. Other formats and rules in the AT command set keep to IS-707A. Any spaces in the AT command field are ignored and the space in the parameter field should be removed if it is not necessary unless otherwise specified.
3. BASIC INTERFACE CONFIGURATION 3.1. Baud Rate Set-up This section provides basic information on setting the data communication rate [baud rate] on the Rm interface between MT2 and TE2. 3.2. Serial Interface The default transfer rate is set to 115200bps with support to 230400bps. On the RS232 Serial connection. NOTE: changes to +IPR rate are written to default NV memory in F0 profile independent of the &W command. Use &W command to write +IPR changes to F1-5 user profiles. 3.3.
Special: Set command Command TE2 Æ MT2 $$Connect_Baud= $$ Connect_Baud = (OK | ERROR) Response TE2 Å MT2 1: Modem displays baud rate set by +IPR command together with Connect message after a circuit switched connection is established. E.g. If IPR is set to 19200, the connect message should display Connect 19200. 0: Displays only connect message. In this case the modem only display Connect after a circuit switched connection is established. 3.4.
