CE 

 

 

Two or four independent serial ports that are jumper selectable for RS-422 or RS-
485 
2-Port Models:    DSC-200/300, DSC-200/300IND 
4-Port Models:    QSC-200/300, QSC-200/300IND 

 

As a PCI device, all these cards require no hardware configuration.  These cards are automatically configured by the 

computer's BIOS or operating system and are Plug & Play compatible. 

A special interrupt status register is provided to manage the shared interrupt line.  These cards completely adhere to 

the PCI 2.1 specification. All PCI registers are properly implemented so users can be assured that no conflicts with other 
properly implemented PCI devices will occur. 

High clock speeds and large FIFOs will greatly reduce CPU overhead, making these cards an ideal choice for heavy 

multi-tasking environments. To maintain maximum signal integrity, these cards use a four-layer board design. 

 

Surge Protection 
     Non-surge protected models DSC-100, DSC-200/300, QSC-100, QSC-100-D9, QSC-200/300; ESC-100D, 
ESC100DB, ESC-100-D9, ESC-100M and have a clock multiplying feature allowing data rates as high as 921.6 kbps. 

Surge protected models (IND indicator in the model/part #) DSC-100IND, DSC-200/300IND; QSC-100IND, QSC-IND-

D9, QSC-200/300IND; ESC-100DIND, ESC-100DBIND, ESC-100IND-D9, ESC-100MIND can achieve data rates up to 
115.2 kbps. Each signal line of these surge protected models comes with surge suppression capable of sustaining up to 
40A 20ms peak transient surges, a clamping voltage of 30V and a peak energy dissipation of 0.1 Joules. 

 

The two serial ports share a single interrupt line and are addressed in a continuous block of 16 bytes. 
Each card has two 16750 UARTs containing 64-byte FIFOs. 
External connections are provided via two DB9 male connectors. 
 

The four serial ports share a single interrupt line and are addressed in a continuous block of 32 bytes.  
Each card has four 16750 UARTs containing 64-byte FIFOs. 
External connections are provided via one DB37 female connector.  
A cable is provided to convert the DB37 female into four standard DB25 male connectors. 
 

The eight serial ports share a single interrupt line and are addressed in a continuous block of 64 bytes.  
Each card has eight 16750 UARTs containing 64-byte FIFOs. 

 

Eight-port cards come in three different connector styles: 
Models ESC-100D, ESC-100DB, ESC-100DIND and ESC-DBIND have a DB78 female connector and include a 

DB78 male to 8-DB25 male connector cable. 

Models ESC-100-D9 and ESC-100IND-D9 have a DB78 female connector and include a DB78 male to 8-DB9 

male connector cable. 

Models ESC-100M and ESC-100MIND do not include an external cable but have 8-RJ11 connectors on the card 

bracket.
