2.10.3 DSENET® (EXPANSION MODULES)
NOTE: As a termination resistor is internally fitted to the controller, the controller must
be the ‘first’ unit on the DSENet link. A termination resistor MUST be fitted to the ‘last’ unit on
the DSENet® link. For connection details, refer to section entitled Typical Wiring Diagram
elsewhere in this document.
NOTE: DSE6110 MKII & DSE6120 MKII modules does not support the DSE2510 or
DSE2520 display modules.
DSENet® is the interconnection cable between the host controller and the expansion module(s) and
must not be connect to any device other than DSE equipment designed for connection to the
DSENet®
Cable Type Two core screened and shielded twisted pair
Cable Characteristics
120 Ω
