2.  Feature Summary 
Ethernet Port 
IEEE 802.3 10/100BaseT Ethernet compliant. Shielded RJ45 connector 
accepts standard CAT5-type 8-conductor unshielded twisted-pair (UTP) patch 
cables. Supports multiple simultaneous protocols. 
RS485 Ports
Two half-duplex 2-wire RS485 ports (A / B / Signal Ground / Shield). These 
ports allow a selection of various master and slave protocols. 
RS232 Port
One RS232 port that can be used to configure the unit, update the internal 
firmware, upload/download files or act as a control protocol port. 
Toshiba ASD Ports
Three common serial (aka logic level) ports for connection of Toshiba 7-series, 
9-series, 11-series or VF-nC1 ASDs. ASD connections use the same standard 
RJ45 style 8-conductor UTP patch cables: any standard CAT5 Ethernet cable 
(found in most electronics stores) 5 meters or less in length can be used. ASD 
connections are automatically established and continuously monitored: no 
drive configuration needs to be performed to connect the unit to the drives. 
Just plug it in – it’s that simple. 
Power Supply
When connected to Toshiba ASDs via the ASD1 / ASD2 / ASD3 ports, can be 
either powered directly from the attached ASDs, or from the auxiliary power 
(“AUX PWR”) input jack. All other non-Toshiba applications require the use of 
the AUX PWR input to supply power to the unit. When more than one power 
source is connected, the unit will draw its control power from the source with 
the highest supply voltage.
