Setting the Data Bus Address and the Starting Wireless Zone ID
The M1XRFTW "two-way" transceiver must be addressed and enrolled as the 1st zone expander (Data Bus Address # 2) on
the M1 or M1EZ8 Control. For extended range and coverage up to 3 additional M1XRFTW transceivers may be installed. If
installed these must be enrolled as the 2nd, 3rd, and 4th zone expander (Data Bus Addresses 3, 4, and 5) on the M1 or M1EZ8
Control. If another hardwire or wireless expander is presently enrolled at one of these addresses it will be necessary to move
that device to another address in order to make accomodation for the M1XRFTW transceiver. Refer to Appendixes A, B, & C for
additional details on the use of multiple transceivers.
Data Bus Address Information: Every device attached to the M1 or M1EZ8 Data Bus must have a valid address setting 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 5 is for Serial expanders. This grouping of devices into different types allows devices in different groups to use the
permits same or similar address numbers to exist in each device group type. All devices except keypads utilize a bank of 4
miniature DIP switches for setting the address number. Each switch has 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.
M1XIN Expander versus M1XRFTW Wireless Expanders (Transceivers):
A single ELK-M1XIN Hardwired Zone Expander (M1XIN) adds 16 hardwired zones at a time to an M1 or M1EZ8 Control. The
data bus address determines the zones numbers (starting and ending) of that group of 16 zones. See Table 1-1. If additional
M1XINs are installed each must be assigned a different address, usually the next available, which sets the zone numbers
(starting and ending) of that group of 16 zones.
A single M1XRFTW Wireless Transceiver/Zone Expander can add up to 144 wireless zones to an M1 or M1EZ8 Control.
The primary or 1st M1XRFTW must be installed and enrolled at data bus address #2, so the first wireless zone will always be
Zone 17. If the full compliment of 144 wireless zones is added then the last wireless zone will be Zone #160. (17 + 144 = 160).
It is very important that no hardwired zone expander ever be assigned a data bus address that would result in a conflict between
a wireless zone and a hardwired zone. In a mixed system of hardwired and wireless zones if any hardwired zone expanders
are enrolled in the range of zones 33 through 160 then an entire group of 16 wireless zones is lost for every hardwired (16
zone) expander installed.

M1XRFTW Wireless ExpandersM1XIN Zone Expanders
As seen in Tables 1-1 and 1-2, Zones 17 to 31 are associated with data bus address 2, which is where the primary (1st)
M1XRFTW must be setup and enrolled. And even though up to 144 wireless zones may be added with a single M1XRFTW, up
to 3 additional remotely mounted M1XRFTW may be installed to increase or expand the wireless coverage range. In
additional M1XRFTW units are added they must be setup and enrolled at addresses 3, 4, and 5 respectively.
Recommendation: Avoid setting up and enrolling hardwired expanders at any of the data bus addresses where a wireless
zone might someday be needed.
