DB9 Female-to-Female Null Modem Cable, 1.8m – JAYCAR

Same null modem cross-wiring as the shortie, but with 1.8m of reach. Your two serial devices are on different sides of the room? This cable gets them talking without a tangle of extensions. The TX/RX lines are swapped so both ends handshake correctly — a straight-through lead simply won't do that job

• Null modem pinout — cross-wired TX/RX for proper device-to-device serial communication
• 1.8m length covers across-desk and short cross-room runs
• DB9 female connectors on both ends for standard RS-232 ports
• Not a straight serial cable — use this when connecting two similar devices together
• JAYCAR branded, dependable for legacy industrial and office serial links
