RS-422 Outputs
The RS-422 outputs send MEI protocol commands
to Marshall’s IMD line of monitors. Each output has
exactly the same signal. Up to 128 screens can be
connected to each output. These output ports also
pass Image Video or TSL v4.0 protocol commands
from the Control Input, embedded in the MEI
protocol. See Page 22 for specifications.
Control Input
The RS-422 Control Input receives Image Video or
TSL v4.0 protocol commands from an external
controller. These commands are then embedded in
MEI protocol and sent to the IMD monitors. See
page 22 for specifications.
RJ-45 Network Interface
The RJ-45 network interface is used to connect the
NCB-1004 to a standard TCP/IP network. The NCB-
1004 is operated via an embedded web interface.
See page 7 for configuration details.

included power supply, be sure that the polarity of
the DC input is correct:
