After starting up, the DT-800 scans the modules connected to it in order to detect
how many and what modules are and if there is any problem.
During the scan, the control module carries out the assignment of bus addresses
and after that an AUTOLINK, which consists in identifying those receivers / modulators
paired (eg DT-301/302 with DT-101/102). This function is essential for a proper
definition of the SERVICES LIST. In order to this assigment works, is necessary to
make the wire connections before starting up. Otherwise you will should made
assigments manually, with the consequent loss of time.
The scanning process takes about ten seconds. After it, it displays on the screen
a list of all the modules identified. If the process takes longer, maybe there is a problem
with the wiring or the CPU.
4.5 Main Screen
The main screen shows the list of all the modules identified.
At the top of the screen the text MODULES FOUND indicates the number of
modules detected and below a list with the names of each one of the modules.
If the modules detected are more than four, the list is rotating, that is, it rotates on
a sequential order to show all the elements.
The modules are identified as follows:
DT-XXX-SY-MZ
Where:
XXX
SY
MZ
The bottom of the screen shows the current STATUS of the modules. If
everything is correct it shows the message "OK. PRESS ENTER TO SETUP" (Fig. 9).

Indicates the name of the module.
S means SLOT and Y is a number equal to the slot position in the
subrack case. This position is the one the module assigns
automatically every time you turn it on. If it does not correspond to
the actual position can be changed manually, but it does not affect
the operation for practical purposes.
M means MODULE and Z is a number that identifies the receiver or
modulator module (1 for the first module, 2 for the second one).
