The Status LED will be steady yellow when module is in the inhibit state.
•
If the Status LED is flashing yellow, the module is in the inhibit state and communicating with an SMD.
•
The three LEDs to the right of the display indicate the display function. The function is selected by a short press
of the SET button.
ADDRESSING
When the ADDR LED is lit, the display shows the module address. To change address, hold the SET button
until the ADDR LED begins to flash. While the ADDR LED is flashing, the address can be changed using the
3 n 4 keys. The34 keys have auto-repeat function and the n button can be used for quickly increasing or
decreasing module address by 10. When the address has been set, press the SET button to exit.
The address range for modules is limited to 32-255.
IMPORTANT: Every network device (module or SMD) MUST have unique address. Two devices with same
address will create bus conflict and defunct whole setup.
IMPORTANT: Never change address while station is in use! Changing address requires re-configuration of
each SMD on the network. Address should be manipulated only during setup.
NOTE: We recommend setting addresses by functional groups as this will help during configuration. For
example, if you need three modules for stack control and rotators on 20 meters, start addressing from #100, 101,
102. The use #110, 111, 112, etc. on 15 meters and so on. There is not problem if some addresses are skipped
and shorter addresses do not make communication faster.
When the USER LED is lit, the display shows address of the controller connected to the module. A module may
have only one controller a time. uLINK DATA modules show the "owner" controller address directly; DATA
modules have one logical unit which can have only one owner at a time. The "owner" display for uLINK RELAY
modules is more complex because these modules can be divided into as many as 4 independent units and each
unit can have different owner for each of its R ports. The USER display scrolls owners of R ports. The left
decimal point indicates Unit 1, the middle decimal point indicates Unit 2, the right decimal point indicates Unit 3,
and the middle/right decimal points indicate Unit 4. The display shows X-YZ where X is the R port and YZ is the
R port user's (owner) address. When a module is configured as a slave (expansion module) the display will
scroll SLA-YZ where YZ is the address of the master module.
When display shows module USERs, buttons have no functions.
Operation with the DATA LED lit and the function of the bottom row of LEDs is specific to each module type and
will be described later for each type of module.

uLINK MODULES Settings
Every module has four (4) buttons, a set of status LEDs and a 3 digit display.
Description below is valid for all modules.
STATUS LED provides information about the state of the module.
The Status LED flashes red when module confirms that the data wires are
•
connected with the proper polarity and sees the network. The LED will
flash for two second after each received packet.
The Status LED will be steady red when the module receives a data
•
packet or query addressed to the module. The LED will remain on for two
seconds after every command is received.
The Status LED will be steady green for 2 seconds during transmission
•
when the module is part of an active transmitting path.
