PARALLEL TO SERIAL MODE, HARDWARE HANDSHAKING

The serial port of the 232SPS2 module is wired as a DCE device. For proper operation the following connections must be present:

1.Transmit Data (TD) from the printer (DTE) must be connected to Pin #2 on the 232SPS2 module.

2.Data Set Ready (DSR) from the printer must be connected to Pin #6 on the 232SPS2 module.

3.Signal Ground (SG) from the printer must be connected to Pin #7 on the 232SPS2 module.

If port powering the 232SPS2, these connections are recommended:

4.Request to Send (RTS) from the host must be connected to Pin #4 on the 232SPS2 module.

5.Data Terminal Ready (DTR) from the host must be connected to Pin #20 on the 232SPS2 module.

Some printers may require one or more of the following connections:

6.Clear To Send (CTS) from the printer should be connected to Pin #5 on the 232SPS2 module.

7.Data Carrier Detect (DCD) from the printer should be connected to Pin #8 on the 232SPS2 module.

NOTE: IBM PC’s (or compatible) serial ports and serial printers are both DTE devices. Therefore, a null modem cable ( like a serial printer cable!) must be used when connecting a PC’s serial port to a printer. A null modem cable or serial printer cable should not be used to connect to the 232SPS2 (unless your device is a DCE -- such as a modem).

For proper operation the following connections must be present:

1.Transmit Data (TD) from the printer (DTE) must be connected to Pin #2 on the 232SPS2 module.

2.Receive (RD) from the printer must be connected to Pin #3 on the 232SPS2 module.

3.Signal Ground (SG) from the printer must be

connected to Pin #7 on the 232SPS2 module.

If port powering the 232SPS2, these connections are recommended:

4.Request to Send (RTS) from the host must be connected to Pin #4 on the 232SPS2 module.

5.Data Terminal Ready (DTR) from the host must be connected to Pin #20 on the 232SPS2 module.
