2.3 Port Connection Specification

The DI-2004 router has two serial ports and one Ethernet port.

2.3.1 PIN description of each port on the DI-2004

1. The Serial Ports of the DI-2004 Router

The DI-2004 router has two serial ports. The jacks are three rows, 44 pins and high

density. The ports have the same PIN description. They can be deployed to be

synchronous or asynchronous methods, so they can connect to synchronous

MODEM(such as TAINET T-1496) or asynchronous MODEM(such as 3Com USR) for

entering special network. For synchronous method, the DI-2004 router also support

the physical protocol of V.35, capable of connecting to baseband MODEM(such as

ASCOM AM64000A ) with a maximum speed of 2Mbps to achieve the high-speed

access goal.

PIN Description of Serial Ports on the DI-2004 is shown as the following table:(PIN in

the table and figure is signed on corresponding location of the jack)
