SATELLINE 3AS NMS operates in a store and forward fashion in the Basic Repeater mode This means that the radio modem acts as a repeater station i e it first receives a message from the radio interface buffers the received data the maximum size of a message is 1 kB and after the reception it transmits the buffered data to another radio modem Only correctly received valid messages are forwarded Note BASIC REPEATER MODE WORKS ONLY IN ONE REPEATER SYSTEMS If there are two or more repeater stations on the same radio frequency a message will be bouncing between the repeater stations forever in an infinite loop Instead addressing must be used in systems that include more than one repeater in order to prevent such situation and ensure that a message finally reaches the intended radio modem The Advanced Master and Advanced Slave modes must be used in those cases see the next two chapters In case a radio modem is in the range of both original transmitter and the repeater units it will receive a message twice In other words the duplicate messages appear on the serial interface Terminal equipment can be also connected to the serial port of the repeater station If the radio modem is already receiving a message to be forwarded the data coming simultaneously from the serial port will be buffered until the store and forward procedure has been completed The store and forward procedure will be completed before transmitting any data

F User Guide Version 6 0 13 SL COMMANDS Controlling the terminal device DTE can instruct the radio modem to make an action This is accomplished with the help of the SL commands which can be used during data transfer in the Data Transfer Mode For example DTE may change the frequency or the output power of transmitter or DTE may enquiry current settings from the radio modem SL commands must be enabled before they can be used by setting the SL commands parameter ON in the Programming Mode An SL command is a one continuous string of characters which is separated from other data by pauses that are at least three 3 characters long The continuous here means that there are no pauses between the adjacent characters inside the SL command on the serial line No extra characters are allowed at the end of an SL command The serial interface settings are the same as in normal data transfer In case the radio modem is receiving a message entering an SL command to the radio modem will terminate the reception and the SL command is processed When the power of a radio modem is switched off the configuration settings of a radio modem always return to values defined initially using the Programming Mode thus resetting any settings changed using SL commands during power on It is however possible to save changed settings permanently by using a special SL command In case you need more information on the time delays related to the use of SL command

FF If the transmitting radio modem and the receiving radio modem has different settings data will not be received correctly 6 4 Error checking The purpose of the error checking is to detect possible errors happened in the data transfer The radio modem transfers user data over the radio link by fitting it to sub frames and adds checksums to the transmitted data In case the error checking is switched on the receiving modem calculates the checksums and verifies the received data before it forwards the data to the serial port SATELLINE 3AS NMS supports three different methods of error checking in order to verify that the received data is proper No Error Check In this mode the received data is NOT verified at all This is the fastest mode because received data is given out to the terminal device immediately after it has been received This is the default mode and it is recommended in case the user protocol includes the error checking feature of its Own Partial Error Check This mode means that the radio modem checks the received data in small data blocks and sends the validated sub messages to DTE Once an error is detected the rest of the message is ignored That is if an error takes place in the middle of a message then the first part of the message is forwarded to the terminal device but the data inside the erroneous sub frame and the rest of the data will be ignored Full Error Check In this mode the radio modem waits until the
