In addition, the transmission word address setting switches SW of the same number as the maximum transmission words are provided along with a transmission word address setting part 4 containing strobed inverters 6 connected to the setting swithces SW respectively and having exclusive OR functions. Then the switch SW is turned on and off in response to an address but BT. Thus it is possible to change optionally the transmission word addresses which are added to all transmission words.
