CABLES AND ADAPTERS General This appendix provides supplementary data on cables and adapters used in various MOSCAD-M systems. The following applications are covered: • RTU-to-Computer/Terminal Connections • RTU-to-Modem Connections • RTU-to-RTU Connections RTU-to-Computer/Terminal Connections For a 25-pin or 9-pin D-type connector, use the FLN6457 cable kit, in order to connect one of the RTU RS-232 ports to a computer or terminal.
For a 9-pin or 25-pin connection, use the FLN6458 cable kit to connect one of the MOSCAD-M RTU RS-232 ports asynchronously to a modem. (The RTU serves as DTE.) The kit includes a cable with RJ45 modular jacks on both ends and an RJ45 to 9- pin and 25-pin male D-Type adapter (see Figure 2).

CABLES AND ADAPTERS 2. The RTU will not receive unless it receives a DCD=on signal from the modem. 3. When using a modem in auto-answer mode (connected to a computer port) for remote service, the RTU does not support the RTS/CTS protocol, as the port is designed to operate with a local computer as well as with a modem.
CABLES AND ADAPTERS RTU-to-RTU Connection RTU-to-RTU Asynchronous Communications Connection This section provides data on the cable (not supplied) recommended for the RTU- to- RTU RS-232 asynchronous interconnection (refer to Figure 3). The following table defines the RTU port for this connection type. Port No.
