You can control up to eight single
OMX-SW8x8NT

To control via RS-232 and RS-485, do the following:
1. Connect the video sources and acceptors, the appropriate audio sources and
acceptors, and the power cord to each
OMX-SW8x8NT
unit.
2. On each
OMX-SW8x8NT
unit, set the SELF ADDRESS dipswitches, as
required

(see Table 5).
3. Connect the RS-232 port on the first unit to the PC

.
4. Interconnect the RS-485 ports on all the
OMX-SW8x8NT
units: from the
RS-485 port on the first
OMX-SW8x8NT
unit, to the RS-485 port on the
second
OMX-SW8x8NT
unit, and so on – up to the RS-485 port on the last
unit.
5. Terminate the RS-485 line as described in section 6.1.2.
