Addresses
All modules and devices annunciated on the MXL are identified by an address
(MMM-DDD). Each address is in two parts: a module address (MMM) and a device
address (DDD). The number identifying the module may be as high as 253, and the
number identifying the device may be as high as 254. Enter all leading zeros for
module and device addresses or use the SPACE key to eliminate the need to enter
the leading zeros. For events specific to a module, the device address is not required.
Fixed Addresses
A module may be assigned to any address on the System, except for some fixed
addresses that have already been assigned. (See the Fixed Module Addresses Table.)
The modules communicate to the MXL Control Panel through a serial communica-
tions network called MNET. The System continuously supervises all of the modules
for presence and proper operation. You may assign a module to any address on the
System, and assign addresses in any order, mixing different types of modules and
leaving gaps in the numbering, provided you do not use the fixed addresses.

The following modules occupy an address on the System, but have no devices (and
no device addresses).
• MKB
• NET-7
• RCC-1/-2/-3
• RCC-1F/-2F/-3F
• CMI-300
• RCM-1
• NIM-1W/-1R
Numeric Keypad
Use the numeric keypad (keys 0 through 9) when the System asks for a module
number, device number, password, time, date, or other information. The display
shows each number as you press the key (except when you enter a password the
System shows an asterisk for each digit that you type).
