The programmer uses the following connections on the RS-232 ccommunications link:
The programmer can optionally supply data to these additional RS-232 lines:
- RD (Receive Data) -- The programmer sends data to the host computer on this line.
- TD (Transmit Data) -- The programmer recives data from the host computer on this line.
- CTS (Clear To Send) -- The programmer uses this line to tell the host computer to suspend sending data.
- DTR (Data Terminal Ready) -- The host computer uses this line to reset the programmer when the communications link is not in use.
The remaining lines, RTS (Request To Send) and RI (Ring Indicator), are left unused.
- DSR (Data Set Ready) -- Informs the host computer whether or not the programmer has power.
- CD (Carrier Detect) -- Informs the host computer that the programmer is running.
Host computer: Terminal software
To communicate with the programmer, terminal software that supports RTS/CTS flow control must be used. Hardware support for RTS/CTS flow control is a plus, however, it does not guarantee that the terminal software will make use of it. The only terminal program that has been successfully used with the programmer is ZOC v3.x from EmTec. It is available for OS/2 Warp, Windows 95, and Windows NT from EmTec's web site. A few other terminal programs that do not work with the programmer have been tried using hardware with flow control support:
When configuring the terminal software for communication with the programmer, use the following settings:
Test this list again!
- HyperACCESS Lite -- Tested on OS/2 Warp v4.
- HyperTerminal -- Port of HyperACCESS Lite to 32-bit Windows. test
- Minicom -- Tested on RedHat Linux v6.1. test again
- ASCII terminal
- RTS/CTS flow control
- Local echo enabled
- 9600 bps
- No parity
- 1 stop bit
In addition to using RS-232, the programmer uses three LEDs to indicate its status. The LEDs are:
- Active (green) -- Lights when the programmer is running.
- Busy (yellow) -- Lights when the programmer is performing a write or verify operation.
- Error (red) -- Lights when an error has occurred and will remain lit until the error is acknowledged by the user.
