2. Interfacing Protocol
The CL4490 is a DCE (Data Communications Equipment). A DCE can be interfaced to a DTE
using a straight through serial cable (the serial cable provided with the CL4490 is a straight
through cable). Typically, PC’s are defined as a DTE and peripherals are defined as DCE. To
interface a DCE with another DCE, or a DTE with another DTE, a null modem (or a Crossover)
cable is required. The null modem simply swaps pins to convert a DCE to a DTE and vice-versa.
A null modem cable can be provided with the CL4490 on request.
The CL4490 transceivers support the following interface protocols
