Figure 4.2: Connection schematics for Xcom-SMS
(example 2: system with several devices)
The start-up is automatic once the Xcom-SMS is connected and powered by your system. The
Xcom-SMS will perform different sequences indicated by the bi-coloured LED (red/green) situated
next to the communication cable. These sequences are summarized below:
1. Start-up of the Xcom-SMS. The bi-coloured LED will blink orange (green and red at the same
time) 2x repeatedly.
2. If your system requires an update the communication module will perform it automatically
depending on the contents of the SD card. It can be the update of one configuration file or
a complete system update. It can be quick or long, depending on its contents and can take
from a few seconds to several minutes (update of the entire system). When an update starts
the bi-coloured LED lights up for 1.5 seconds in orange, then keeps blinking in red.
3. Once the update is completed the module will access the micro SIM card and the
configuration files on your SD card. This sequence is indicated by the LED blinking in orange 2x
repeatedly.
With one other device in the system the termination on the other device should be
put to T as in "Terminated". See figure 4.1.
An incorrect setting of the terminations can lead to an erratic running of the system
or impede its updating.
With more than two devices in the system all Studer devices should be put to O as
"Open" apart from the devices at the ends of the communication chain. These
devices should be put to T as "Terminated". The Xcom-SMS does not have a
termination since it has only one communication cable port. See figure 4.2
An incorrect setting of the link ends can lead to an erratic running of the system or
impede its updating.
By default, the termination is terminated (position T) on each of Studer Innotec SA's
products.
