18 8960ENC Instruction Manual
Configuration
Local Onboard Module Configuration
The 8960ENC module can be configured locally using the rotary and toggle
switches shown in
Figure 6 . Two LEDs (CONF and 2nd) indicate status of
the configuration process. These four components perform the following:
• Function (rotary) switch addresses a desired function for configuration
and provides two sets (banks) of 16 functions (0 through 9, A through
F), although not all positions are used.
• 2nd (second function) LED when on, indicates that the rotary switch is
addressing the second (Bank 2) of functions (see
Table 5 on page 20 )
that control the optional 8900FSS Frame Sync Submodule.
• SW1 (paddle) switch actuates or selects the desired setting for the
selected function when the switch is held momentarily in either the up
or down position.
• CONF (configuring) LED when on, indicates the module is initializing
or processing configuration information.
Note Function switch position F (Recall) in Bank 1 can be used to return the
module configuration to the factory default.
The following onboard jumpers are used to permit or lockout remote
control and set reference input impedance.
• Remote Control Lockout – When a jumper is placed across pins 1 and 2
of jumper block JP1 (see
Figure 6 ), module output mode settings are
adjustable from the Local on-board switches only. To have both Local
and Remote access, set the jumper across pins 2 and 3.
• Reference Input Impedance – When a jumper is placed across pins 1
and 2 of jumper block JP10 (525 line reference) or JP11 (625 line refer-
ence), Reference Input is terminated into 75
Ω
(see Figure 6 ). To have
high impedance termination, set the jumper across pins 2 and 3 of the
appropriate jumper block.
