1. Star II (CHIP) Controller Input/Output Numbering
on Controller and MIRO Devices
The Input/Output Logic Presentation covers the application and numbering logic for Input Points and Output relays on all Star II and MIRO configurations. It is aimed primarily at engineers and technicians.
Additional resources include the Sales Training Presentation and the One Door Application Presentation. Sales Training covers the basic features and capabilities of the Star Controller Family, NexSentry Manager NT Host and the StarGaze Linux Host. The One Door Application Presentation covers the basic concepts of Electronic Access Control for new Sales personnel as well as new system engineers and technicians.
A special Honeywell Sales Training Presentation is available exclusively for Honeywell personnel. It eliminates the NexWatch Hosts and specifies the HSM/XSM/EBI systems.

2. Star II Input/Output Logic
Star II Controller - Stand-Alone or Host Connected: 255 inputs and 96 outputs on any combination of up to 16 MIRO devices.
The Star II Controller has 16 Inputs and 4 Relays on the main board itself. The on-board 16/4 I/O is defaulted as MIRO #1 and can’t be changed. Up to 15 additional MIRO and/or WIRO modules may be connected via S-NET wiring to reach the desired number of Input Points and Output Relays.
The standard Star II handles 2 Readers, however, Personality Chips can be installed for 4, 8 or 16 Readers.
Self explanatory.

3. The Input and Output numbering for the Star II is a major departure from the legacy (SEEP Protocol) family of controllers. All points are listed in an X.Y format where
X = the MIRO Address, and
Y = the point location on the MIRO
Various MIRO and WIRO models support from Input Points and Relays.
The on-board MIRO in the Star I is locked as Address 1. The 16 on-board Inputs are always Addresses
The 4 Relays on the Star II are logically addressed as
The example above shows the minimum Star II configuration. If a 4-Reader Personality Chip were installed, the main board alone still has enough Input Points and Relays to handle most 4-Reader applications with DKR or S-NET Magnetic Stripe Readers.
The Main board supports two Wiegand Protocol readers directly, but needs additional WIU modules for more than two.

4. This example shows a Star II with a 16 Reader Personality Chip installed. The controller is connected to a MIRO 16/8. The system then has a total of 32Input Points and 12 Relays. Unless there were at least four doors with both Entry and Exit Readers, this combination of components will not have enough Relays to handle 16 physical doors.
The next two slides will show two different arrangements of MIRO devices that can accomplish raising the Relay total to 16.

5. This example adds two MIRO 4/2 modules downstream from the MIRO 16/8
This example adds two MIRO 4/2 modules downstream from the MIRO 16/8. The system now has a total of 40 Input Points and 16 Relays.
The MIRO 4/2 is primarily intended for use in more distributed applications where it is desirable to place the MIRO device near the door it is controlling. In many applications, especially using the NexWatch DKR Readers, a single MIRO 4/2 can control 2 doors. The 4 inputs allow two Door Status Switches (DS) and two Request to Exit (REX) devices. Two relays control two locks. The DKR Readers have built-in audible and visual indications for both Door-Held-Open and Door-Forced-Open conditions so no additional relays or components are needed.

6. This application is functionally the same as the previous one
This application is functionally the same as the previous one. Its only purpose is to illuminate the fact that the MIRO devices can be installed in any sequential order. There is no “Preferred” way.
The only standing recommendation is to distribute the Readers and MIROs across the four S-NET ports on the Star II controller. This will add a degree of redundancy since not all of any one kind of device will be dependent on a single communication link.
Also note that is is perfectly fine to mix Readers and MIROs together in the same S-NET link. Readers have been omitted from these drawings in order to focus on the Input/Output issues. Other PowerPoint shows are available dealing with specific Reader concerns.

7. The drawing above is intended to show only one possible way to fully load a Star II Controller with 255 Input Points and 96 Relays. There are almost an infinite number of possible permutations and combinations that could do the same thing.
Remember the bottom line:
Up to 15 additional MIRO/WIRO devices can be added to a Star II Controller.
The MIRO/WIRO devices can be distributed across the four S-NET links in ANY physical and address order.
You can not exceed 255 Inputs and 96 Relays, no matter what combination of MIRO/WIROs you attach to the controller.
