  • Page 83: Appendix B. Remote Control

    Overview This appendix describes the protocol and message command set for remote monitor and control (M&C) of the CDM-800 Gateway Router. The electrical interface is an EIA-232 connection (for the control of a single device), and data is transmitted in asynchronous serial form, using ASCII characters.

  • Page 84: Packet Structure

    CDM-800 Gateway Router Revision 0 Appendix B MN-CDM800 The Controller, which is in charge of the process of monitor and control, is the only device that is permitted to initiate, at will, the transmission of data. Targets are only permitted to transmit when they have been specifically instructed to do so by the Controller.

  • Page 85: B.4.2  Target Address

    CDM-800 Gateway Router Revision 0 Appendix B MN-CDM800 B.4.2 Target Address In EIA-232 applications this value is set to 0. The Controller sends a packet with the address of a Target – the destination of the packet. When the Target responds, the address used is the same address, to indicate to the Controller the source of the packet.
