Route 56 Developer Toolkit ABSTRACT: DLC1.C DLC1.C is a Direct Memory Access interrupt driven SDLC/HDLC test program. The base address 300 Hex and IRQ11 is used for this test. To build the program, the R56_IO.C file must be linked from the \LIBRARY directory. Cables: For SDLC\HDLC mode, transmit, receive, Tx Clock, and Rx Clock are needed. The program may be used in a stand alone loop-back configuration, or with another PC with a Route 56 or SDLC adapter installed. Please note that TSET (Transmit Signal Element Timing) is the EIA-530 equivalent of TT, the RS-232 signal Terminal Timing. For a loop-back plug connect the Transmit signal(s) to the receive signal(s) and the TSET (EIA-530) or TT (RS-232) signal(s) to the RxC signal(s). For Loop-Back Plug: For Single Ended (RS-232, MIL-188/114) Connect Tx to Rx Connect TSET or TT to RxC For Differential Interface (RS-530, V.35, MIL-188/C, etc.) Connect Tx+ to Rx+ Connect Tx- to Rx- Connect TSET+ or TT+ to RxC+ Connect TSET- or TT- to RxC- Build Dependencies: DLC1.C * R56_IO.C * R56_IO.H * Z16C32.H * Denotes that files are located in the \LIBRARY directory.
