  • Page 2 11 YA(-) 14 YB(+) D-sub 25-pin connector D-sub 9-pin connector 17 SG Shield wire To the JIR-301-M via CDM 11 YA(-) 14 YB(+) 17 SG (Fig. 2.2-1) Shield Wire Connect only one end of the shield to the FG terminal to avoid a ground loop. If both ends of the shield wire are connected to the FG terminal, the circuit will be closed, resulting in a ground loop.
  • Page 3 The terminator is mounted at the end of the wire when connecting multiple peripheral devices to a personal computer. The terminator prevents signal reflection and disturbance. Do not connect a terminator to the communication line because each JIR-301-M has built-in pull-up and pull-down resistors instead of a terminator.
  • Page 4 4. Communication Procedure Communication starts with command transmission from the host computer (hereafter Master), and ends with the response of the JIR-301-M (hereafter Slave). • Response with data Master Slave Command When the master sends the Read command, the slave responds with the corresponding set value or current status.
  • Page 5 5. Shinko Protocol 5.1 Transmission Mode Shinko protocol is composed of ASCII codes. Hexadecimal (0 to 9, A to F), which is divided into high order (4-bit) and low order (4-bit) out of 8-bit binary data in command is transmitted as ASCII characters.
  • Page 6 (4) Acknowledgement Header Delimiter Address Checksum (06H) (03H) (5) Negative acknowledgement Header Error Delimiter Address Checksum (15H) code (03H) Header: Control code to represent the beginning of the command or the response. ASCII is used. Write command, Read command: STX (02H) fixed Response with data, Acknowledgement: ACK (06H) fixed Negative acknowledgement: NAK (15H) fixed...
  • Page 7 5.3 Checksum Calculation Checksum is used to detect receiving errors in the command or data. Set the program for the master side as well to calculate the checksum of the response data from the slaves so that communication errors can be checked. The ASCII code (hexadecimal) corresponding to the characters which range from the address (instrument number) to that before the checksum is converted to binary notation, and the total value is calculated.

  • Page 11 To transmit continuously, an interval between characters which consist of one message, must be within 1.5 character transmission times. If an interval lasts longer than 1.5 character transmission times, the JIR-301-M assumes that transmission from the master is finished, which results in a communication error, and will not return a response.
