SRC-32 Installation and Operation Manual

INSTALLATION

Input jumper configuration:

The SRC-32’s inputs may be configured for one of three operations:

1 – Optically isolated wet source (5 to 24 vdc)

2 - Optically isolated dry (5-volt source)

3 - CMOS/TTL 5-volt compatible input

Relay jumper configuration:

The SRC-32’s relays may be configured for normally open or normally closed con-

tacts. The SRC-32 is shipped configured for normally open contacts. To configure

for normally closed contacts, move the jumper from the NOx position to the NCx

position. x refers to the relay number. There are sixteen relays installed in the SRC-

32. These jumpers are located between the relays and front panel connectors.

It is recommended that all cables connected to the SRC-32 should be looped through

ferrite cores to suppress RF. Surge protection with RF filtering such as the Tripp

Lite “ISOBAR 4” is also suggested for the power transformer. The purchase of an

inexpensive uninterruptible power supply (UPS) will provide back up in case of

power outages. Check out our web site for lightning protection links.

CAUTION!

Installation of the

SRC-32 in high RF

environments should be

performed with care.

Shielded cable is sug-

gested for all control,

audio inputs and out-

puts. All shields should

be tied to the “CHAS-

SIS GROUND” termi-

nals. The station

ground should be con-

nected to the chassis

ground screw (CH1)

located near J13 as

viewed from the rear.
