Operating instructions

BAL SX302 ETH EN 3.1 11
Socket connection The units are set up as TCP server by default. The data is transmitted to port 8000
via a socket connection (factory settings). Other ports between 2000 and 9999 can
be set in menu item P (see chapter 4).
In menu item P, the decimal points of the port number flash one after the other.
The digit with the decimal point flashing can be set to the value requested by
means of the menu key [Q].
Time-out In menu item t, it is possible to set whether a time-out occurs, and if so, after what
time. Time-out means that a minus sign appears on the display if the unit has not
received a data telegram after a defined time.
Switching output The devices dispose of a switching output (relay) with potential-free change-over
contact (NC, NO, CO).
When setting OFF in menu item r, the switching output can be activated with the
following command:
Activate switching contact: $Q@1
Deactivate switching contact: $Q@0
When setting 1, 2 or 4 in menu item r, the command $Q@1 causes a wiping pulse
at the switching output with a duration of 1, 2 or 4 seconds.
When setting A1, A2 or A4 in menu item r, the switching output automatically gives
a wiping pulse with a duration of 1, 2 or 4 seconds with every telegram ending.
The relay switches after realized telegram ending.
The wiping function is suitable, for example, for activating optical and acoustic
signal transmitters.
The status indicator OUT of the control computer is lighted with active
switching output.
Display test In menu item F, you can set whether a display test is to be performed after the
operating voltage is applied.
The display test can be also activated via the serial interface with the following
command:
Display test on : $T1
Display test off $T0
The display test has priority over blanking and flashing.
Demo operation mode If the setting PlAy is selected in menu item F, random characters are displayed.
In this case, it is impossible to activate the unit.
Flashing Flashing of the display can be activated with the following command:
Flashing on: $F1
Flashing off: $F0
If$F1 is sent in the data telegram, the succeeding digits will flash until the end of
the data telegram or until$F0 is sent in the data telegram.
Flashing of the display can also be activated by application of the H signal to
functional input F1 (priority compared to the commands).
For units provided with an LRD® display flashing is not possible.
