Function of {RS-232} button

By pressing this button, toggles the another controller device.

Once the RE-350 detects that the {RS-232} button was pressed, the RE-350 will send an Event data packet to the PC through the RS232C I/F to tell the PC that the operator is trying to change the mode. The Event data packet will differ according to the

RE-350's RS232C I/F from active to inactive for communication with the PC or

RE-350's current mode.

Note: RS-232C hand shake control signals originate from the PC side (DTE) in this document. In this docu-

20h .........................................................................“Event Data Packet”

B0h.........................................................................“E-response Data Packet”

30Fh .......................................................................“FP Data Packet”

Every data packet consists of 5 bytes of data. If the

RE-350 receives another kind of data packet which will be described below, the RE-350 will disregard the data

packet and while the RE-350 recognizes the data packet is incorrect, the RE-350 will inactivate the CTS signal line to the PC.

ID number

Each RE-350 can have an individual ID number, (0,1,2 or 3), which will be set by digital switches 3 and 4 on the rear panel. The RE-350 will neglect the command data packet which has a different ID number. The PC can recognize which RE-350 responds.

Parameter

Each data packet has this parameter. If the data packet does not need the parameter, the content should be set by

$0000.
