Remote Programming Outline
Programming can be performed from outside the system through telephone lines using a Remote
Administration Interface (RAI) or via the RS232 call logging port. For external modem access the
system must be equipped with the optional RAI card. See Installation Manual for details.
In such cases, the programming is done from commercially available data terminals, usually a PC
and modem.
CPC-EX Bus Monitor / PC Programming Serial Port
With the introduction of the CPC-EX a second serial port has been added for use when collecting
Bus Monitor data and performing remote programming. It is located directly on the PCB of the
CPC-EX card at the front just above the tab used to slide the card in and out of its slot.
On the CPC-EX card the call logging port is reserved exclusively for call logging and the second
connection is provided on the CPC-EX card itself for the connection of a maintenance PC only.
Programming is no longer possible via the call logging connection.
To connect to this a cable will need to be prepared to connect from the PC to the 10-pin
connector. Below is a diagram for wiring to a 9 way D-type connector which is common on most
modern PCs. If your PC connector is different please consult your computer expert to get the
equivalent cable designed and made.
The 10-way plug is available from most large electronic component suppliers and are not
expensive.
Without this cable there is no way to link a PC for programming or collection of Bus Monitor ( fault
finding ) data.
In addition to the second serial port the maximum port speed has been increased from 9600 bps to
19200bps. The ports' usage is also separated, i.e. The call logging port is for call logging only and
the new port for system monitor and programming only. When in programming mode the call
logging is suspended and buffered and resumes when programming is complete. When
programming mode is exited the system will return top call logging and bus monitor modes.
The following commands can be entered from the operator extension for control of the new port:
#99(ID CODE) Enter On site programming mode
#90
Normal bus monitor mode
#91
Accumulated bus monitor mode
#92
Polling bus monitor mode
#93 call logging toggle is deleted and no longer operates.
