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. The kit includes a cable with
RJ45 modular jacks on both ends, an RJ45 to 25-pin female D-Type adapter, and an
RJ45 to 9-pin D-Type adapter.
The RTU port configuration is as follows:
Port No. Configurator Definition
1B
RS-232 UART Local Computer (MDLC)
2 RS-232 UART Local Computer (MDLC)
When a User Port is defined as Computer/Terminal with
DTR support:
1. The RTU will not transmit unless it receives a DTR=on
2. The RTU will not receive unless it receives a DTR=on
signal from the computer/terminal.
signal from the computer/terminal.
