Abstract

PROBLEM TO BE SOLVED: To simplify the setting operation of an address, etc., by setting data at a terminal equipment by a bar code reader in a system communicating between the terminal equipment and a central controller based on set data on an address previously set to the terminal equipment. SOLUTION: The terminal equipment 10b is provided with a data transmission part 31a for transmitting set data through a wire, a data processing part 32 and a power source 37 feeding power to each part of the equipment 10b in addition to the bar code reader 36. When the equipment 10b reads a set starting bar code, this is transmitted to a monitoring terminal equipment 2. At the time of receiving data from the equipment 10b, the equipment 2 shifts to a set mode and waits. When the equipment 10b reads set data bar code next, set data is transmitted and the equipment 2 receives this to store in a receiving part 27. A display part 26 displays this data to visually confirm its set content.

First, in the terminals 2 and 3, the normal mode is set. When an address setting signal is received in the normal mode (step S3).
1) Check whether the address is already set in the storage unit 27.

If the address has not been set, the mode shifts to the address setting mode, and the received address is displayed on the display unit 26 as shown in FIG. 15 (step S32). Ignore the signal and do nothing. In the normal mode, a character font indicating a place name is displayed on the screen of the display unit 26, and the on / off state of the operation unit (switch SW1) is displayed.

When the operation section (switch SW1) is operated while the reception address is displayed on the display section 26, the reception address is stored in the storage section 27 (steps S33 → S34), and FIG. An acknowledgment (Ack) signal is set in the indicated return data field and returned to the central controller 1 (step S35). Central controller 1 receives this Ack signal (step S23). Next, the address to be transmitted is changed and the address setting signal is transmitted again (step S24), and thereafter, this is repeated.

FIG. 16 shows a case where the address update processing of the central control unit 1 in step S24 is performed via an operation unit (not shown). That is, the central controller 1 checks whether a new address has been input via the operation unit (step S41), and transmits the input address (step S42).

First, it is determined whether or not the address indicated by the address counter is still set in the terminals 2 and 3. Check whether the address is a free address (step S51). If the address is a free address, the address indicated by the address counter is transmitted (step S52). On the other hand, if the address is not a free address, the address counter is incremented (step S5).
3), returning to step S51 to check whether the address is a free address.
