Product identity

The Black Box BC00708 is a 15 ft DB25 serial extension cable with a 25-pin male connector on one end and a 25-pin female connector on the other. It is built for RS-232 links between legacy industrial gear, lab instruments or older PCs that still use the DB25 interface.

What the extension changes

The moulded strain relief protects the solder joints when the cable is routed through cable trays or around rack corners. The 4.5 m length lets you bridge the gap between a fixed wall port and a mobile test bench without adding a second cable and an extra junction point.

Build and daily use

Lifetime warranty coverage signals that the moulded hoods and pin contacts are rated for repeated mate cycles in workshop conditions. The straight-through pinout means the cable behaves as a transparent link, so existing RS-232 software sees no change in handshake or data lines.

Questions about this item

Will the DB-25 connectors on this BC00708 cable need replacement after long-term use?

The moulded DB-25 male and female connectors are built as a permanent part of the 15 ft cable, so no connector replacement is expected.

What is the maximum reliable length before RS-232 signal degradation on this 15 ft extension?

At 15 ft (4.5 m) the cable stays well within the RS-232 recommended distance, so signal loss is not the limiting factor.

Does the BC00708 generate heat or draw extra power when used continuously all day?

As a passive serial extension with no active electronics, it produces no heat and draws no power of its own.
