APPENDIX A: 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 RS232 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.
When the connector is facing upwards, the left-hand pin is Pin No. 1,
and the right-hand pin is Pin No. 8.
