Model: 232SP9

RS-232 Surge Protector CE

Introduction
B&BElectronics’ Model 232SP9protects RS-232 portsfrom damage caused by large voltage peaks from
lightningand other power problems. The Surge Protector uses 600W Transient Voltage Suppressors to protect all 9
pins. It has one DB-9 male and one DB-9 female connector with all 9 pins passing straight through. TheTVSs are
connectedbetween the ground screw andpins 1,2,3,4,5,6,7,8,and 9. The 232SP9 will suppress any voltage levels
above12 volts without affecting the normal RS-232 data.
The232SP9 is placed inline, between the data cable and the RS-232 port, as close to the protected port as
possible. The ground screw must be connected to earth ground. Aminimum of 12 AWG copper wire is recommended.
B&B’sModel CU15B is 1.5 x 0.016 in (38 x .25 mm) copper cut to length for ground connections that are longer than a
few feet(one meter). If this devicei s not properly grounded it will not protect RS-232 lines.
