dS-NET I/O Switcher Technical Specifications

SWITCHING
Crosspoint switch initial resistance:	<0.5R per leg
Bus to load connector initial resistance:	<0.2R per leg
Channel-to-channel cross-talk:¹	<–140dB, 20Hz to 15kHz
¹ Measured on either bus, routed from any channel, with any other channel carrying hostile signal to other bus, 50R source impedance, 100kR load impedance, balanced or unbalanced operation.
All-channels cross-talk:²	<–135dB, 20Hz to 15kHz
² Measured on either bus, routed from any channel, with all other channels carrying hostile signal to other bus, 50R source impedance, 100kR load impedance, balanced or unbalanced operation.

MAXIMUM RATINGS
Crosspoint switching voltage:	250V
Crosspoint switching current:	2A ³
³ Note that repeated switching of high currents will damage the relay contacts and increase switch resistance. It is not recommended that the crosspoint relays be subjected to currents beyond 100mA or switched loads above 5W if specified switch resistance is to be maintained.
Load current:	12A (2A through crosspoint)
Balance-test amplitude:	28dBu (19.45V RMS)

SERIAL CONTROL
Standard	RS232 or RS485 (jumper selectable)
Protocol	dS-NET
Connector:	2 x D-sub-9 male
Addressing:	up to 64 dS-NET devices can be addressed, Address selectable by DIP switches on rear panel.

PHYSICAL
