4.3. Connecting Devices to the APS-16


1                     Access the Command Mode.

2                     Determine which port will be used for connection to the new device (e.g. Port 3).

3                     Clear Buffer: Type /S [Enter] to display the Status Screen. Check the "BUF" column, which lists the amount of data stored for each port.


a) If the Status Screen shows data stored in buffered memory, invoke the /E command to clear the buffer.

/E nn [Enter] Where "nn" is the name or number of the port buffer to be cleared.

b) Note that cleared data cannot be recovered.

4. Attach an appropriate DB9 cable to an RS-232 serial port on the device you intend to connect.

a) External Modems and other DCE Devices: Use a standard serial cable.

b) PCs and other DTE Devices: Use a standard null modem cable.

1                     Connect the other end of the DB9 cable to a vacant APS-16 RS-232 port.

2                     Select communication parameters for each port as described in Section 5.
