JP10, JP110 - CH1 Clock Detection Filter
- 3-pin jumper that filters out non-data spikes if clock is not
present.
Non-dot
position - presence of clock is detected on the first few positive transition of clock from CH1.
Dot
position - presence of clock is detected after about 1 ms of positive transitions of clock from CH1.
JP10,110 normal position - Non-dot
.
JP15, JP16, JP17, JP18 - Alarm clock frequency
3-pin jumper FACTORY SET to provide clock for the time
out alarm circuitry.
DO NOT ADJUST THESE!
Figure 2.3 shows the correct positions.
.
JP25,JP125 - Clock or data presence alarm enable/disable
3-pin jumper FACTORY SET to enable clock or
data presence alarm circuitry on CH1.
Dot position
-enables clock or data presence alarm on CH1.
Non-dot position
-disables clock or data presence alarm on CH1.
JP26,JP126 - Clock or data presence alarm enable/disable
3-pin jumper FACTORY SET to enable clock or
data presence alarm circuitry on CH2.
Dot position
-enables clock or data presence alarm on CH2.
Non-dot position
-disables clock or data presence alarm on CH2.
2.4.2 On-Card Switches
S3, S103 - Initial Channel Select (ICS) Mode
- 4-position DIP switch Selects the Initial Channel Select mode
when JP1,2,3, JP101,102,103,in Dot and JP4, JP104 in Non-dot.
S3, S103 positions 1,2,3,4 to ON - ICS is enabled.
In the ICS mode, the initial channel can be either
CH1 or CH2 by switching the front panel Manual Select switch to either CH1 or CH2 and then back to
the Auto position.or by grounding either Remote 1 or Remote 2 pins on J8 and then grounding the
Remote reset pin on J8 causing the 1582-14 to go back to Auto in the channel last selected remotely if
both channel alarms are clear or both channels are in alarm. The initial channel can also be selected if
both channel alarms are clear or both channels are in alarm..
S3, S103 positions 1,2,3,4 to OFF - ICS is disabled (Minimum Auto switching, Return to Last
State Mode)
The 1582-14 goes to the last state (CH1 or CH2) it was in when in Auto after Manually or
Remotely switching and returning to Auto. Auto switching occurs only if current channel alarms and the
other channel is clear.
S3, S103 normal position - 1,2,3,4 to ON
S4, S104 - CH1 CLOCK TIMEOUT
- Selects the time in seconds (0.1 to 0.9) of data absence in channel 1
before an alarm is indicated.
S5, S105 - CH2 CLOCK TIMEOUT
- Selects the time in seconds (0.1 to 0.9) of data absence in channel 2
before an alarm is indicated.
