This adapter will enable you to connect a 25 pin serialcable to a 9 pin connector at the computer. 9 PIN D-SUB FEMALE to the Computer. 25 PIN D-SUB MALE to the Serialcable. 9-Pin 25-Pin; Carrier Detect: 1: 8: Receive Data: 2: 3: Transmit Data: 3: 2: Data Terminal Ready: 4: 20: System Ground: 5: 7: Data Set Ready: 6: 6: Request to Send: 7: 4. The DTE (PC) has the male connector (shown below), and the DCE (peripheral) has the female. RS-232 Maximum Cable Length. The maximum cable length for RS-232 is 50ft, but in practise depends on baud rate, cable specific capacitance and ambient noise. The table below contains some rules-of-thumb from experiments done by Texas Instruments years ago.
Wiring Diagrams for Conventional (non-CHIRP) Transducers
These diagrams are for the use of professional installers. Before attempting to rewire a transducer connector you should:
1. Check to see if an adapter cable exists (see the Adapters page).
2. Transformer design calculator. Check to see if the transducer is a Mix and Match 600W or 1kW model. If so, you can simply change the Mix and Match cable.
Do not change a connector without professional advice. Some transducer versions are incompatible with certain brands of equipment.
