(864) 843-4343.

DB25 Serial Extension Cable (Part Number CA104)

The CA104 is a standard DB25F to DB25M serial extension

cable. Extend a DB25 cable or locate a piece of hardware where

it is needed with this six foot (72 inch) cable. The connectors

are pinned one-to-one, so the cable is compatible with any

device or cable with DB25 connectors. The cable is fully

shielded against interference and the connectors are molded to

provide strain relief. Dual metal thumbscrews secure the cable

connections and prevent accidental disconnection.

DB25F to DB9M Adapter – RS-232 Converter (Part Number CA140)

Converts an RS-232 DB25 Male connector to an RS-232 DB9

Male connector.

DB25F to RJ45 Modular Adapter (Part Number RJ25S8)

DB25 Female to RJ45 Modular Adapter. Excellent choice for

using available infrastructure wiring. Item ships unassembled

and can be easily configured without tools.

Terminal Blocks

Terminal Block (Part Number TB04-KT)

The TB04-KT terminal block can be used to break out serial and

digital DB25 connectors to 25 screw terminals. The TB04-KT

makes it easy to field wire networks with different pin out

configurations. Compatible with any cable with a DB-25 male

connector.

The TB04-KT ships with a terminal block, a 6 inch piece of

slotted Snap Track, and two DIN-rail mounting clips.

Terminal Block Kit (Part Number KT104)

The KT104 terminal block kit bundles a DB25 breakout board, a

6 inch piece of slotted Snap Track, two DIN-rail mounting clips,

and a DB25 serial extension cable.

Developed to simplify field wiring requirements, the Terminal

Block KT104’s onboard DB25F can be connected directly to

boards that include DB25M cables.

Card Setup

Address and IRQ Selection

The 7803ec is automatically assigned memory addresses and IRQs by your motherboard BIOS or by a “Plug-

n-Play” Operating System. Adding or removing other hardware or moving the adapter to another slot may

change the assignment of memory addresses and IRQs.

Clock Modes and Baud Rates

The 7803ec derives a 125MHz clock from the PCI express link for the Baud Rate Generator (BRG) which is

divided by a clock prescaler (1 or 4) and a 16-bit clock divisor to obtain a sampling clock of 16X, 8X, or 4X

the serial data rate. The BRG offers a wide range of possible baud rates. Under Windows and Linux, the

best choice of divisor is made automatically by the driver. The bit rate error is within the +/– 2%

recommended tolerance for proper serial communication.
