About This Manual
We recommend that you read and understand everything in this manual before setting up and using
the product. However, we recognize that users have different styles of learning: some will want to set
up and use this kit while they read about it; others will open these pages only as a "last resort" to check
on a particular specification. Therefore, we have designed this manual to be used either as a "how
to" procedural manual or a reference guide to important data.
Additional assistance is provided in the following ways:
The User Interface features a help facility that provides brief messages on keyboard commands.
The complete Schematic Diagram is included at the back of this user's manual.

  • Page 13 Z80185/195 D EVELOPMENT ILOG ANUAL ESCC DTE Pinning on J10 Since the ESCC channel signals on the Z80185 are named appropriately for the DTE role, the following signals on J10 are driven from (or received into) the pins of the same name on the ESCC channel: TxD, RxD, RTS, CTS, DCD, DTR, and RxC.
  • Page 14 Z80185/195 D EVELOPMENT ILOG ANUAL SETTING UP THE HARDWARE (Continued) ASCI0 DTE Pinning on J12 TXA0 drives TxD on J12. RxD on J12 is received into RXA0. /RTS0 drives RTS on J12 CTS on J12 is received onto J7-10 (/CTS0 on the schematic). It can be jumpered to the 185’s /CTS0/RxS pin on J7-9, in which case this pin should be programmed for the /CTS0 function.
  • Page 15 Z80185/195 D EVELOPMENT ILOG ANUAL ASCI0 DCE Pinning on J13 (Continued) DTR on J13 is received onto J14-14 (/DSR0 on the schematic). It can be jumpered to the 185’s PIA12 pin on J14-13, or PIA11 on J14-15. The signal on J14-16 (/DCD0O on the schematic) drives DCD on J13. It can be jumpered from the 185’s PIA11 pin on J14-15, or PIA10 on J14-17.

Note: The file, which preceded, is not intended to be an executable program. Rather, it is the test file for the disassembly command in this Debug Monitor. DISTEST includes all the instructions that can be executed by the Z8018x family processors.
  • Page 21 Two hex files, DISTEST.HEX and TSTRST20.HEX, containing binary/absolute programs for the Z80195 processor are provided with this development kit. You can use the Zilog Z800 assembler and object utilities provided with this kit, or third-party Z80 or Z180 software development tools to generate your own 185/195 programs and hex files.
