4.9 Power On Sequence
There is no requirement for a specific power-on sequence. Any unit
within the system can be powered in any order.
4.10 RM16 configuration
4.10.1 Configuring the system
If configuring an M16/RM16 system for the first time, or having add-
ed additional M16 or RM16 units to the communications backbone,
an interrogation sequence, via one RM16, will need to be initiated.
This is referred to as Enumeration.
Note: When connecting an RM16 to an M16 for the first time,
the Remote LED on the M16 front panel may flash. This is indi-
cating that the connected system requires Enumeration.
If using multiple RM16s within a system, choose just one to run the
interrogation sequence. The information obtained will automatically
be forwarded to the other RM16s within the system.
■ From the RM16 Root menu (see FIG 4-7. RM16 root menu )
select Edit by pressing the associated illuminated button below
the menu.
■ Select System from the Edit menu.
■ Select Enumerate from the System Configuration and Testing
menu.
■ Select Yes from the Enumerate Units and Allocate Addresses
menu.
The message Enumeration beginning - Please wait... is dis-
played.
This initiates the interrogation process. Each M16 and RM16 in the
system will return its own unique serial number and a unique ad-
dress will be allocated to that unit. As this happens the following
messages appear for each unit found:
M16 Serial Number ##### has replied
Allocating Address $$ to Ser No. #####
(where ##### is the serial number and $$ is address number)
Once every unit on the communications backbone has been interro-
gated and an address assigned, the RM16 will display:
Enumeration ended - You may continue
■ Press Return to return to the Edit menu.
■ Press Return to return to the Root menu
NOTE: This interrogation process is only required when an ex-
isting system is modified or a system has been newly config-
ured.
