7.7 Remote Programming

Use MISC 1 (2): DCS Compact-II or iDCS 100 System
To remotely program a system, connect a customer-provided Local external modem to a
serial interface connector on a MISC 1(2) card(See Figure 7.8).
Use an RS232C cable as shown in Figure 7.8. When the modem needs to be more than 15
feet away from the KSU, use shielded computer cable. Attach a male DB9 connector to the
MISC 1(2) end and then attach one that matches the requirements of the modem to the
other end. This cable must not exceed 300 feet.
Use MMC 804 to set the transmission parameters and the MISC port to be used.
Use MCP1 or OfficeServ 100 System
The OfficeServ 100 can be remote programmed with a PC equipped connected to the
MCP1 LAN port or via serial interface of the MCP1.
