2.4 DTE/DCE Selection

To simplify connections to other devices, each port on the DSC-100 is equipped with a jumper block that allows the port to be configured as either a DTE- or DCE-type device. This allows the DSC-100 to connect to either DTE- or DCE-type devices without using a null modem cable. The DTE/DCE selection jumper blocks are illustrated in Figure 5.

J2 is used for serial port 1, closest to the bottom of the board.

J1 is used for serial port 2, closest to the top of the board.
