2.1 PRODUCT DESCRIPTION

The Patton Model 503P and 503PC guard PC parallel interfaces

against data loss and damage due to transient surges. These units
employ a solid state circuit using Silicon Avalanche Diodes, and can
handle repeated surges up to 1500 Watts. The Model 503P connects
directly between the DB-25 parallel port of a PC or workstation and the
parallel printer cable. The Model 503PC connects to the parallel printer
cable, and then plugs directly into the 36-pin Centronics® printer port.
Both units divert surge energy to chassis ground through the metal
connector shell. For complete protection of your parallel line, we
recommend that a Model 503P and 503PC be used together, one at
each end of the line.

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 503P and 503PC adds
four benefits to your syste.

1. High Surge Capability

. The 503P and 503PC

dissipate up to 1.5 kwatts for up to 1 mes.

2. Quick Response

. The 503P and 503PC feature a response
time of 500 nsec, 503PC clamps at +8V and -3V the 503P
clamps to 6.8V

3. Low Impedance

. Connect the 503P directly to RS-232 ports
with minimal load to your system — about the same as a
gender changer.

4. “Fail Safe” Design

. Unlike some other surge suppressors, the
503P fails short to ground should your system experience an
extreme transient or severe current overload. Therefore, Iif
the unit fails, data and surges are diverted to ground instead of
back into your equipment.
