27. mmunication pauses have been used to separate serial messages from each other However the use of non real time operating systems frequently used on PC type hardware often adds random pauses which may result in the user data splitting into two or more separate RF transmissions This may cause problems especially in the systems including repeater stations In order to match the operation of the radio modem to the user data the Pause length parameter can be adjusted on the programming menu It may have any value between 3 and 255 characters The default value is 3 characters Notes o The absolute time of Pause length is depending on the serial port settings For example 1 character is 1 04 ms at 9600 bps 8N1 10 bits o The maximum absolute time is always 170 ms independent from the value of the Pause length given in the set up o An increase in the Pause length increases the round trip delay of the radio link correspondingly this is due to the fact that the radio channel is occupied for the time of the Pause length after each transmission the time it takes to detect a pause If this is not acceptable the TX delay setting may also be useful in special cases 26 SATELLINE M3 TR1 User Guide Version 2 5 6 3 3 TX delay The radio modem can be configured to delay the beginning of a radio transmission by 1 65000 ms This function can be used to prevent packet contention in a system where all substations would otherwise answer
