  2. Hello all, I am trying to download a new program to a AB 1746-BAS SLC 500 BASIC board via RS-232 connection through a Windows 98 laptop running Hyperterminal. While the BASIC board is connected I verify connection by waiting for the board to print out its information in the Hyperterminal program and then enter "CLEAR", "NEW" and finally, "LIST" in Hyperterminal to wipe any program from the board and verify the board is clean respectively. Then I load the new program via a .TXT file using the "Send Text File" option within the Hyperterminal program. After the program has finished loading I than type "LIST" to verify it has copied over correctly. I than switch the SLC over to "Program Mode" via the key. After doing so I type "RAM" to select the program i just uploaded to the BASIC board and then type "PROG" in the Hyperterminal program. I than receive the "Programming Sequence Failure". If anyone has any advice as to what I am doing wrong it would be greatly appreciated. Below is a list of everything I have set and researched. Thank you in advance, James -Laptop: Windows 98, Hyperterminal -BASIC board (programming): JW1 pin: 1-2 3-4 JW2 pin: 1-2 3-4 JW3 pin: 1-3 2-4 JW4 pin: 5-6 3-4 -RS-232 9-pin connector: Pin 2 connected to Tx Pin 3 connected to RX Pin 5 connected to ground Pins (4/6) crossed DSR/DTR Pins (7/8) crossed RTS/CTS -Hypterminal: Direct Com1 bits per second: 1200 parity: none stop bits: 1 Flow control: Xon/Xoff Settings/properties: -> Emulation VT100 -> ASCII line/character delay: 30 milliseconds check box: Append line check box: Wrap lines... -Manuals: 1746-rm001 1746-pm001
