4.3 Startup
After startup, the DC LED will light and the network indicator lights will go through an on/off
sequence.
The power DC LED should always be lit; the link and No Video lights will eventually glow upon
establishing of a good network link and the absence of an input video signal, respectively.
The sync LED displays as described in the Front Panel section.
Important: Before any signal connection can be made, at least a valid IP address (the unit's
identity for the network) and a subnet mask must be assigned to the unit. Refer to the
Connections chapter for details on how this can be done.
4.4 Connector Pin Assignments
Modular socket pin assignments
The modular socket pin assignments are such that similar sockets of different modules may be
connected back to back with reversed cable (RS-232 interfaces excepted). See the figure below
for the socket pin numbering convention used. For 2-wire RS-485 links, I/O is through pins 1 and
2 of socket 3.
Pin assignments of the three modular sockets. For 2-wire RS-485 use pins 1 and 2 of socket 3.
Note:
Polarity indications for RS-422/485 are based on a convention used by BT, which may
conflict with other implementations. Pelco systems, for example, use an implementation for
which you have to connect Siqura (+) to Pelco (-) and vice versa.
