6 ft CMG-rated DB9 null-modem cable

This six-foot serial cable carries a CMG fire rating for in-wall installation in commercial and educational AV projects. It crosses the transmit and receive lines so two DTE devices communicate directly without a separate modem.

Check your ports and wiring plan

Verify that both pieces of equipment present a DB-9 male interface and expect a null-modem pin-out rather than a straight-through cable. Confirm the 1.25-inch connector depth fits the gang box or monitor mount you are using and that the run length of six feet reaches between the two devices.

Shielded, molded construction with thumbscrews

Full shielding blocks EMI and RFI on the RS-232 link while the molded jacket provides strain relief at each end. Integrated thumbscrews lock the DB-9 plugs securely, preventing accidental disconnection during daily operation.

Questions about this item

Does the Cables To Go 52166 include any adapters or gender changers in the box?

The package contains only the 6 ft DB9 male-to-male null modem cable with molded connectors and thumbscrews; no adapters or gender changers are included.

When should I choose the 6 ft CMG-rated version instead of a shorter or non-CMG cable?

Choose this 6 ft CMG-rated cable when the run must pass through walls or plenum spaces where a CMG fire rating is required by code.

How does the crossed transmit/receive wiring affect a direct RS-232 link between two DTE devices?

The crossed wiring swaps pins 2 and 3 so two DTE ports can communicate without a separate null modem adapter, enabling a straight-through RS-232 connection.
