  • 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 DCL-33A has built-in pull-up and pull-down resistors.
  • Page 4 4. Communication Procedure Communication starts with command transmission from the host computer (hereafter Master), and ends with the response of the DCL-33A (hereafter Slave). • Response with data Master Slave When the master sends the Read command, the slave Command responds with the corresponding set value or current status.

  • 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 DCL-33A assumes that transmission from the master is finished, which results in a communication error, and will not return a response.
