CHAPTER 3: Installation
3. Installation
3.1 General
The Stat-4, Stat-8, and Stat-24 are delivered completely assembled. Install each mux on top of a bench or shelf,
or optionally mount it in a 19" rack (via rack adapter kits). Mechanical and electrical installation procedures
appear in the following paragraphs.
After installing the mux, refer to
Section 3.8
for system configuration information and procedures (including
sub-channel bit rate, data format, and flow-control mode selection).
If you encounter a problem, refer to
Chapter 5
for test and diagnostic instructions.
3.2 Site and Power Requirements
Power.
Install within 5 feet (1.5 m) of a grounded AC outlet capable of furnishing 115 VAC or 230 VAC,
according to the nominal supply voltage of the unit.
Ambient Requirements.
The stat mux will operate properly in any ambient conditions suitable for operation of
electronic computer equipment and peripherals. The stat mux, however, can operate without performance
degradation over a wide range of temperatures 32 to 122°F (0 to 50°C) at relative humidities up to 95%,
non-condensing.
Grounding.
The stat muxes have a rear ground screw, which is used for grounding all the metal parts of the
chassis.
3.3 Description of Internal Jumpers
WARNING
Avoid electrical shock! Always turn the power switch off and disconnect the power
cable from mains before opening the stat mux.
General.
The Stat-4, Stat-8, and Stat-24 have three internal jumpers. Refer to Figure 3-1 for Stat-4 and Stat-8 and
to Figure 3-2 for Stat-24, and use the following description.
1. INIT/NOR jumper. Use this jumper to select the default set of configuration parameters stored in the
stat mux. The jumper has two positions:
•
NOR: Normal operation. The stat mux uses parameters selected by the user during the last
configuration session.
•
INIT: Initialization. The stat mux uses the default configuration (determined by factory and common
to all stat mux units). To select the default configuration, set the jumper to INIT, then apply power to
the stat mux, or press the RESET button while the stat mux is powered. The default configuration is
loaded during power-up.
Factory setting is NOR.
