Setting the M1XRF Data Bus Address and the Starting Wireless Zone ID

Every device on the M1 RS-485 4-wire data bus must have a valid address setting (from 1 to 15) within it's device type.
TYPE 1 is for Keypads, TYPE 2 is for Hardwire and Wireless Input expanders, TYPE 3 is for Output expanders, TYPE 4 is
for Serial expanders.  The device types allow address numbers to be re-used in each different device type.  There are 4
address switches, each with an OFF or ON position (binary value 0 or 1) and decimal equiv. value of (1, 2, 4, or 8).  The
total decimal value of the "ON" switches determines the data bus address.  Set the switches to the desired data bus
address by referring to Tables 1-1 and 1-2.  A small screwdriver may be helpful.  See important information before
proceeding to "Data Bus Enrollment".

    

VERY IMPORTANT!   PLEASE READ!

Since Hardwire and Wireless expanders share the same device type and same bus address range,
unintentional data bus "Conflicts" are possible with M1XRF Wireless Receiver(s) and M1XIN Hardwired
Expander(s) installed on the same control.  These conflicts can be avoided with proper understanding of
the issues and careful planning and execution during installation.  The important point to remember is
that M1XRF Wireless Receivers and M1XIN Zone Expanders share the same data bus addresses.  Below
are some issues and recommendations to avoid addressing conflicts:

M1XIN Expanders

:  A single ELK-M1XIN Hardwired Zone Expander (M1XIN) provides 16 hardwired zones.  The data bus

address SETS THE ID OF THE STARTING ZONE of each 16 zone group.  See Table 1-1.  If additional M1XINs are installed,
each must have a different address (usually the next available) to set the starting zone of the next 16 zone group.  I.E., Each data
bus address equates to a specific group of 16 zone IDs.  Everything works fine as long as there are NO DUPLICATE addresses.

M1XRF Receivers

:  The differences between a ELK-M1XRF Wireless Receiver and a ELK-M1XIN Zone Expander are:

1) A single M1XRF Receiver can add up to 144 wireless zones to the control.  These are assigned in groups of 16 at a time.

One stipulation is that to have 144 total wireless zones the first group of 16 must begin at zone 17 and the balance of the
wireless zones must be sequential through zone 160.  If any hardwired zone expanders are enrolled in the range of
zones 17 through 160 you lose one entire group of 16 wireless zones for every hardwired (16 zone) expander installed.

2) For added range and coverage redundancy multiple "like branded" M1XRF Wireless Receivers can be installed on the

bus.  Redundant receivers can be assigned to any unused data bus address as long as it doesn't conflict with another
Type 2 device.

NOTE: The data bus address of an M1XRF Receiver does not inherently set starting wireless zone number. Even so,
Elk strongly encourages Installers to set the data bus address of the first M1XRF Receiver to the starting zone ID as
depicted in Tables 1-1 and 1-2.   While the actual data bus address of the M1XRF could be address 10 and the first
group of 16 wireless zones could be programmed as 17-32, the disadvantages of doing this are potential zone
numbering conflicts when M1XIN Hardwired Zones Expanders exist.

Other important considerations when installing an M1XRF:

a) Although wireless zones are allocated in Groups with a minimum number of 16 zones each, you are not required to

utilize all 16 of the zones in each group.

b) Care must be taken to ensure that wireless zones NEVER spill over into data bus addresses already assigned to a

M1XIN Hardwired Zone Expander, or vs. versa.

c) Regardless of where the wireless zones start we strongly suggest that all additional wireless zones be contiguous and

that no M1XIN Hardwired Zone Expanders be installed at data bus addresses associated with those wireless zone
numbers.  Data Bus Addresses whose zone IDs are effectively "overlapped" by wireless zones are considered
"reserved" for wireless use and should not be used by a hardwired zone expander.  See Appendix C.

d) The last wireless zone number can NEVER be assigned higher than zone 160.  Put another way, zones 161 through 208

cannot

 be wireless zones.

e) The maximum number of wireless zones is 144, therefore the last wireless zone number cannot be greater than 160.

Example:  

You decide to create 64 contiguous wireless zones.  And the starting wireless zone ID is set to "17" (associated

with data bus address 2).  That would mean that zones 17 to 31, 32 to 48, 49 to 64, and 65 to 80 are going to be wireless
zones.  Based on Tables 1-1 and 1-2 it can be seen that zones 17 to 31 are associated with data bus address 2.  Zones 32 to
48, 49 to 64, and 65 to 80 are associated with data bus addresses 3, 4, and 5 respectively.  As a result, addresses 3,4, and 5
ARE NOT AVAILABLE for use by M1XIN Expanders because the wireless zones are overlapping these addresses.

NOTE: Consider whether the system may ever required more wireless or hardwired zones.  If the answer is yes it
would be good to plan the data bus address assignments in such a way that future growth is possible without having
to default the control or totally re-arrange the addresses at a future date.
