2.0 GENERAL INFORMATION  
3.0 INSTALLATION  
Thank you for your purchase of this Patton Electronics product.  
This product has been thoroughly inspected and tested and is  
warranted for One Year parts and labor. If any questions arise during  
installation or use of the unit, contact Patton Electronics Technical  
Support at (301)975-1000.  
Patton's Model 503S is simple to install, and requires no user  
configuration. Follow these installation steps.  
1. Turn your equipment’s power switch off and disconnect the power  
cord from the wall outlet.  
2.1 PRODUCT DESCRIPTION  
2. Unplug (disconnect) the existing connection between the serial  
cable and your DB-25 serial port.  
The Patton Model 503S guards all pins on the DB-25 serial  
interface against data loss and damage due to transient surges. The  
Model 503S employs a solid state circuit using Silicon Avalanche  
Diodes, and has a combined surge handling capacity of up to 36,000  
Watts (1.5kW per wire). Connecting directly between the DB-25 serial  
port of your hardware (PC, modem or printer) and the serial cable, the  
Model 503S diverts surge energy to chassis ground through pin 1 and  
the metal D-shell. For complete protection of your serial line, we  
recommend that one surge protector be used at each end of the line.  
3. Install the Model 503S between the serial cable and the DB-25  
serial port. If the D-shell is not connected to chassis ground, use  
the grounding wire (included) to make an alternate frame ground  
connection. Proper grounding is essential to the operation of the  
Model 503S.  
Alternate Ground Connections  
Warning: These products will not provide complete protection  
should your equipment be subject to a direct lightning hit.  
2.2 SURGE PROTECTION BENEFITS  
The method of surge protection used in the 503S adds four  
benefits to your system.  
MODEL 503S  
SERIAL DB-25  
SURGE  
PROTECTOR  
1. High Surge Capability . The 503S handles up to 36k Watts  
(1500 Watts per wire) of surge energy.  
2. Quick Response. The 503S feature a response time of 500  
nsec, with transient surges being clamped at 27 Volts.  
3. Low Impedance. Connect the 503S directly to RS-232 ports  
with minimal load to your system — about the same as a  
gender changer.  
Figure 1. How to Connect the Patton Model DB-25 to Your PC, Modem or Printer  
4. “Fail Safe” Design. Unlike some other surge suppressors,  
the 503S fails short to ground should your system experience  
an excessive surge.
