5. CONFIGURATION The dual channel frequency transmitter has several operational parameters that require configuration prior to use All of these parameters can be viewed and changed via the console port The console port consists of a small four pin connector and a two position slide switch behind the front panel label Access to the console port can be gained by snapping out the front panel using a wide bladed flat screw driver in one of the slots between the front panel and terminal blocks To use the console port an Austdac MEAN interface A to B USB cable and laptop computer running Hyper Terminal are required For more detail on the console port MEAN 1 interface and their use refer to Austdac document 53 018 11 5 1 CONSOLE PORT OPERATION The console port should be connected to a laptop running a terminal emulation program such as Hyper Terminal via the Austdac interface type MEAN1 and a USB cable as shown in the following photograph 2 CHANNEL FREQUENCY TRANSMITTER 9 OF 24 120 379 12 TYPE SILBUS TX2F USER S MANUAL Issue 01 Photograph 4 SILBUS TX2F console port connected to MEAN1 interface The SILBUS TX2F certification places restrictions on what may be connected to the console port the connection of an interface other than the Austdac MEAN to the console port will invalidate the certification of the transmitter The terminal emulation program should be configured to 19200 baud 8 data bits one stop bit no pari

7. This command is used to display and configure the common set point hysteresis for each of the frequency inputs The hysteresis value is used to stop the set point alarms from switching on and off with any noise that may be present on the frequency input signal For example if the frequency input was currently at 4 93Hz and the set point level was set at 5 2 for a rising alarm the input signal would only need slightly more than 0 07Hz of noise or jitter to cause the set point alarm to randomly switch on and off By setting the hysteresis value to slightly higher than any known noise this random and annoying switching can be eliminated The hysteresis value is common to all two frequency inputs The current hysteresis value can be displayed by simply entering the command name as shown in the example below TX2F TRPHYS Hysteresis level 0 20Hz 0 32m s TX2F If the command name is entered with additional attributes the hysteresis level can be configured to any valid level An example of configuring the hysteresis level is shown below TX2F gt FLTHYS SET 0 30 Setting Changed Hysteresis level 0 30Hz 0 45m s TX2F The range of the hysteresis is from 0 01Hz to 1 0Hz 5 13 ANALOGUE SELECT COMMAND This command is used to display and configure the analogue transmission protocol for each of the frequency inputs Each frequency input can be configured to either Analink or Fastlink transmission protocol The current selecte
