SS 16.1 Installation and Operation Manual
INSTALLATION
INSTALLATION GUIDELINES
Installation of the 16 x 1 in high RF environments should be performed with care.
Shielded cable is suggested for all control, audio inputs and outputs. All shields
should be tied to the EGND terminals. The station ground should be connected to
the chassis ground screw located on the far right side of the 16 x 1 as viewed from
the rear. It is recommended that all cables connected to the 16 x 1 be looped through
ferrite cores to suppress RF. Surge protection with RF filtering such as the Tripp
Lite “ISOBAR 4 or 6” is also suggested for the wall transformer. The purchase of
an inexpensive UPS will provide back-up in case of power outages.
The 16 x 1 is simple to install. The signal inputs, outputs are connected via plug-
gable screw terminals. Installation of the 16 x 1 consists of six steps:
1. Inspection
2.
Removal of the source termination resistors, if applicable
3.
Bench test and option set-up
4.
Mount the unit in a rack or desktop
5.
Connect your equipment to the unit
6.
Label the front panel switches
7.
Serial operation, if applicable
STEP 1: INSPECTION
Please examine your 16 x 1 carefully for any damage that may have been sustained
during shipping. If any is noted, please notify the shipper immediately. Retain the
packaging for inspection by the shipper. The package should contain the 16 x 1, this
manual, 37 pin female D-connector/shell, 7 foot modular cable, 9 VAC @ 500 ma
transformer, modular cable, 9-pin D-Sub adapter and audio mating connectors.
STEP 2: SOURCE TERMINATION RESISTOR REMOVAL
Input sources that are not selected are terminated with a 10K
Ω
. If you do not want
this load applied across the
deselected sources,
it may be removed from each chan-
nel. Each channel has a pair of resistors.
• EXAMPLE:
Channel 1, relays K1 A&B switches the signal; R15 & R21 are the
load resistors. As delivered, all channels are configured with these resistors
installed. To remove the load resistors from a channel, locate via the schematic the
proper resistors for that channel, cut its leads and discard the resistors.
