Connection Data for Data Channel with RS-530 Interface
The functions of the pins in the RS-530 data channel interface connector are
listed in
Table A-3 . The following sections provide information on the cables
required to connect user’s equipment to a data channel with RS-530 interface in
the various timing modes.
DCE Mode
This mode is used to connect to user’s equipment with DTE interface. The user’s
equipment can be directly connected to the FCD-E1LC channel connector using a
standard “straight” RS-530 cable (i.e., a cable wired point-to-point). The
“straight” cable is terminated in a 25-pin male D-type connector at the FCD-E1LC
side.
