Features and Specifications

• 72 inch long shielded cable.
• Female RS232 DB9 connector.
• This cable has NO TTL connectors, its just bare wire for your own connections.
• The connector carries the Tx, Rx, CTS, RTS, V and Ground signals.
• The cable works for 3.3V TTL signals and 5V TTL.
• The cable converts 0v/(3 to 5v) nominal TTL signal to nominal –12v/+12v RS232 serial signal.
• The cable requires +3.3V (+3V to +5V) power from the TTL side to operate.
• The circuitry is built into the cable!

Since these cables do not have a TTL connector, we cannot test them. All type 1, 2, and 3 cables are tested, these are NOT. Failure rate is < 0.25% when testing type 1, 2, and 3 cables. Since this is an electronic component and the end user is responsible for modifying the cable to hook it up to their TTL connection, we cannot warrant or replace defective cables. Only type 1, 2, and 3 cables are tested and guaranteed not to be DOA.
