Adapter Connection
Figure 4.1.3A - Serial Interface Connection
The connector is configured as a DTE (Data Terminal Equipment). It is recommended that the cable length
be 50 feet or less to reduce the possibility of errors from signal distortion. Also, the connectors should be
secured with the proper screws to enable reliable operation. All necessary serial cables should be double
shielded where appropriate.
If the unit is connected to a terminal or computer, a Null Modem cable is required. This null modem cable is
available from EXFO and should be ordered with the CableSHARK. Null modem cables are available in
various configurations. The configuration on Figure 4.1.3A above gives the pin arrangement of a typical null
modem cable.
4.1.4 The Ethernet 10BaseT Connection
The Ethernet 10BaseT port is used to connect the CableSHARK to a PC terminal via a LAN or the Internet.
The connector for this is a female RJ-45 connector on the rear panel of the CableSHARK. When connecting
to your equipment, a crossover cable or straight cable can be used (defined below) depending upon the
network infrastructure. The Ethernet interface is compatible with the TIA/EIA T568A and TIA/EIA T568B
specifications. The pin assignments for this are as follows:
