SRC-8 III Installation and Operation Manual
INSTALLATION
INSTALLATION GUIDELINES
Rear panel dual-row 18-position connector
NOTE: Refer to the appendix for input and relay configuration.
Each input may be configured for wet, dry or 5 volt TTL/CMOS logic compat-
ible inputs. Factory default = DRY
Each relay may be configured for normally open or closed contacts. Factory
default = N.O.
It is recommended that all cables connected to the SRC-8 III 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.
DIP Switch Settings:
DIP 1,2 The board address is set using switch numbers 1 and 2 in normal bina-
ry format:
1 2
0 0
= 0 (master) Set the SRC-8 III that will be connected to your
PC or data link to address 00.
0 1 = 1
1 0 = 2
1 1 = 3
DIP 3,4 Set baud rate
3 4
0 0
= 9600
0 1 = 2400
1 0 = 4800
1 1 = 38400
The Baud rate will be set by the dipswitch on power up or reset. It can also be
changed using the serial port commands at other times, but if the SRC-8 III is reset
baud rate will be set according to the dipswitch settings.

CAUTION!
Installation of the
SS 16.4 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-
nal. The station
ground should be con-
nected to the chassis
ground screw (CH1)
located behind J1 as
viewed from the rear.
