For the Remote Readers type MR, KR, MHR, KHR and CR both of the “Remote Type
Selection” jumpers must be set to Side 1.
For an Impro 4-Channel UHF Receiver both jumpers must be set to Side 2.
Relay Outputs
In order to prevent damage to components, it is recommended that one of the arc-
suppression techniques shown in Figure 3 be used.
BUS ACTIVITY LED INDICATORS
LED's are included in the unit to indicate bus activity as an aid to fault-finding. Green LED's
are used to indicate incoming bus activity, and Red LED's to indicate outgoing bus activity;
these LED's flash when data is being received or transmitted on the associated bus. The
positions of the various LED's on the LED PCB are indicated in Figure 1.
ADDRESS ALLOCATION
GENERAL
An ImproX Unit Location Chart is packed with each ImproX IC LCD Keypad Controller and
IL LCD Keypad Computer.
TYPES OF ADDRESSES
Each ImproX unit is allocated a unique Fixed Address at the factory. This address is stored
in its memory. When the unit is installed in a system, the system allocates a separate
Logical Address to the unit for communication purposes.
Fixed Address
The unit's Fixed Address is recorded on a label attached to the back of the unit. A copy of
this label is attached to the packing box in which the unit is delivered, and a further copy is
packed inside this box.
Address Allocation - ImproNet Systems
ImproNet systems automatically allocate Logical Addresses to units, either on initial
software start-up, or on request, depending on the system configuration. Also, in a system
configured for address allocation on software start-up, when the system software is
started-up after adding a new unit to an existing system, a Logical Address will
automatically be allocated to that unit.
Address Allocation - OEM Systems
In an OEM system, the unit Logical Addresses are allocated individually using commands
available in the ImproX Secure Communications Protocol. Details of this process are
described in the ImproX Secure Communications Protocol document.
