Chapter 5
Setting Internal Jumpers
5.1
Introduction
Jumpers in the the 1088B series clocks are already set up at the factory according to the purchase
order. If it should be necessary to change any jumpers or to enable any new function, you should
follow the instructions in this section.
This section should assist you with understanding and setting the internal main board jumpers in
the Model 1088B. After correctly setting the necessary jumpers, go to Chapter 6, The Setup Menu,
for details on how to configure these signals from the front panel keys. Most settings may also be
configured through the RS-232 port. If you wish to know additional technical details about timing
signals, please see Chapter 7, Timing, IRIG-B, and Pulses.
NOTE:
Values in tables marked with an “*” show default positions.
5.2
Changing Hardware Settings Via Internal Jumpers
The 1088B incorporate a flexible input and output (I/O) selection system, which is made possible
by an innovative internal jumper scheme. Each of the four, standard, rear-panel I/O connectors
can be reconfigured to perform any of the available output functions. Alternatively, any or all of
the I/O connectors can be set to act as an input to the 1088B. However, each of the I/O connectors
is assigned only one specific and exclusive input function.
Besides configuring the four main output connectors, there are other settings that will be explained
in this section. These include whether to use the RS-232 port or one of the standard I/O connectors
for event input signals, setting the frequency reference for the clock, and setting the battery-backed
RAM.
When changing any of the jumpers you will want to refer to the main board layout diagram in
Figure 5.1 to locate jumper positions. Tables 5.1, 5.2 and 5.3 will also help to identify meanings
to the various settings.
