    After installing the MEGAPORT/2 board, the computer must be configured. The first time the machine is turned on with the MEGAPORT/2 installed, an error code of 165 appears on the screen and 2 beeps are sounded after the RAM is counted. This error message indicates that the configuration has been changed and the machine must be reconfigured to recognize the MEGAPORT/2.

  • Page 42: Cs Port Full Modem Control Wiring

    CS Port Full Modem Control Wiring As discussed above, MEGAPORT CS ports regularly provide two modem control signals per port (i.e. CNTL OUT and CNTL IN), which may be used for either modem supervision (DTR/DCD) or hardware flow control (RTS/CTS), under software control.
  • Page 43 Modular Full Modem Control Adaptor To implement full modem control in a modular environment, Equi- nox provides modular full modem control adaptors. These devices consist of two short cables which are plugged into the appropriate adjacent port jacks on an Equinox modular splitter. At the end of the cables is a small housing with two jacks, one providing full modem control and the other data only (see Figure 3-17).

  • Page 44: Special Considerations

    Special Considerations When connecting devices to the MEGAPORT board ports, it is important to understand the difference between DCE and DTE devices. This is to ensure that data flows in the right direction. If DCE and DTE are not wired correctly, communications between the two devices may be blocked.
