DB25-ALL offers dataline surge suppression for any DB25 serial port, regardless of cable configurations. Connects and protects all 25 pins, plus D shell chassis for universal protection of any DB25 application. User-configurable for use with male or female captive DB25 port. Convenient DB25 input and output connects directly to the protected port, obtaining a ground outlet from the computer chassis. Surge suppression is handled with balanced arrays of high-speed avalanche diodes that divert excess energies created by electrostatic discharges away from network interface connections. Network surge suppressors reduce blown interface connections, garbled transmissions, system lock-ups and hard equipment failure by safely shunting dataline surges to ground.
