As shown in the diagram below, connect the CU-733 to the host computer with a cross-mode cable, and to
the modem with a straight-mode cable.
DTE and DCE
With RS-232C specification, DTEs (Data Terminal Endpoint) are generally connected by a cross-mode cable,
and the DTE and DCE (Data Circuit Endpoint) are connected by a straight-mode cable.
The DTE is a device connected at both ends of a communication line as a sender or receiver of data. This
refers to devices such as the BHT placed on the CU-733 and the host computer.
The DCE is a device connected between the DTE and communication line and terminates communication
lines. The DCE converts the respective signals without any change in content. This applies to devices such
as a modem or TA.
