OPERATION
All RS-232 data is ASCII but the number of bits, parity and speed can be changed from settings. The number of
data bits is selected with Setting 37 for either 7 or 8. Parity is selected with Setting 12 and is none, even, odd,
or zero. Zero parity will always set the parity bit to 0. The data speed is selected with Setting 11.
Once the connection to your computer has been made and verified, go to the Setting page and set the baud
rate, parity, number of stop bits, end of block (EOB) format, and leader parameters to match your require-
ments.
All programs sent to the control must begin with a line containing a single % and must end with a line contain-
ing a single %. All programs sent by the control will have these % symbols.
To receive a program, push the LIST PROG key. Move the cursor to the word ALL and push the RECV RS-232
key and the control will receive all main and sub programs until it receives a % sign indicating end of input.
Please note that when using îš“ALLîš”, all your programs must have an address Oxxxxx to be filed. If you do not
have a program number, type in the program number before you push RECV RS-232 and the program will be
stored under that number. You can also select an existing program for input and it will be replaced. An ASCII
EOF character (code 04) will also terminate input. The colon character (:) may be used in place of the O for a
program name, but it is always displayed as O.
When receiving RS-232 data, there is a status message at the bottom of the screen. It will update as follows:
WAITING When you first press RECV RS-232.
LOADING XXX When first % is received; if in XMODEM, XXX is the current block being loaded.
LOADING Onnnnn When program name is received.
RS232 DONE When complete and last % is received.
RS232 ABORT When anything causes abnormal stop.
There is a maximum of 200 programs stored in this control at a time.
To send a program, use the cursor as above to select the program and push the SEND RS-232 key. You can
select îš“ALLîš” to send all of the programs in memory. A setting can be turned on to add spaces to the RS-232
output and improve the readability of your programs.
The synchronization protocol used to send data to slower computers is selected from the Setting 14. Setting
14 may be set to XON/XOFF, RTS/CTS, DC CODES, or XMODEM. Transmission can be stopped with either
the XON/XOFF characters or the RTS/CTS wires.
Parameters, settings, offsets, and macro variables pages may also be sent individually via RS-232 by selecting
the îš“LIST PROGîš” mode, selecting the desired display screen, and pushing the SEND key. They can be re-
ceived by pushing the RECV key.
The settings that control RS-232 are:
11 BAUD RATE
12 PARITY
13 STOP BITS
14 SYNCHRONIZATION
24 LEADER TO PUNCH
25 EOB PATTERN
37 NUMBER DATA BITS
