Jet Mill and Microtek 2800 Controller
I have a mill that is about thirty years old. It is a Jet Mill with a Microtek 2800 controller. This machine works great but I would like to connect this to a computer for programing, it is a pain to type all the programs in on the keyboard with the little monitor. It has an RS232 port with 24 pins, but I cant get the computer to communicate with the controller or vise versa. I have tried a couple of different wiring schemes, my last attempt was straight thru 1-1, 2-2, etc with pin 4 and 20 together. I have the manual that shows the pin layout.
Pin 1 = Ground
Pin 2 = Transmited Data (From 2800)
Pin 3 = Received Data (to 2800)
Pin 4 = Request Data (From 2800)
Pin 5 = Clear to Send (To 2800)
Pin 6 = Data Set Ready (To 2800)
Pin 7 = Ground
Pin 20 = Data Terminal Ready (From 2800)
I am a manual machinist by trade, 30 years doing plus 20 years teaching. I am not an electronics type person. I have a RS232 24 pin cable and a Radio Shack 9 pin connector to computer.
Does anyone have a hint as how to get this to work or if it will work?

com port setting for ProDNC
I found com port setting page for DNCsoftware on internet (refer to photo attached) it may be similar to your software
Please select
CNC Name : FANUC-0M ; 2800 program format most competible to Fanuc-0M
Port : com 1 ; if you are connecting the RS-232 cable to com 1
Baud rate :4800 ; same as 2800 baudrate setting
Character set: ASCII/ISO ; 2800 set ISO
Protocols: Data bits:7, Parity: Even, Stop bits:1
Enable DTR and RTS
Flow control: XON/XOFF for now and try RTS/CTS latter
Buffer size : stay the same
Then you can try to receive a file from 2800
Refer to photo 2 , If your software also have the RED and Green indicators display on the bottom of the screen, those will show the condition of the rs-232 signal. Please record that and let me know the color shows.
