On-Card Jumpers
NOTE:
Dot
position means jumper goes from center pin to the pin nearest the dot on the PCB. Also the first
jumper designation is for switch A (J1) and the second is for switch B (J101).
JP1, JP101 - 3-pin jumper that works with JP3, JP103
In the
dot
position when channel 1 alarms the 1582-14 will switch to channel 2 until channel 2 alarms.
At this point, if channel 1 is still in alarm, the switch will stay on channel 2. When the channel 1 alarm
clears if channel 2 is still in alarm, the switch will switch to channel 1.
In the
non-dot
position, operates in conjunction with
JP3
as noted below.
JP1, JP101 normal position - non-dot
and operates in conjunction with JP3, JP103 as noted below.
JP2, JP102 - Input alarm condition
3-pin jumper
In the
dot
position open is normal operation, ground is alarm
In the
non-dot
position ground is normal operation, open is an alarm.
JP2, JP102 normal position - dot
JP3, JP103 - LATCH to CH2 mode on / off
- 3-pin jumper effective when JP1 is in the non-dot position.
With
JP3
in the
dot
and
JP1
in the
non-dot
, when channel 1 alarms, the 1582-14 switch switches to
channel 2 and stays there until the reset button is pushed on the front panel or by an external closure to
ground on the remote RESET pin on J8, and then it switches to channel 1. (If channel 1 alarms are
cleared ). If in the ICS mode and originally set to CH2 the 1582-14 will not switch if CH2 alarms. Only
the RESET functions (front panel pushbutton or J8 closure to ground) will return the switch to CH1.
With JP3 in the
non-dot
and JP1 in the
non-dot
, when channel 1 alarms the 1582-14 switches to
channel 2 until the alarm on channel 1 clears and then the 1582-14 switches back to channel 1
automatically.
JP3, JP103 normal position - dot
.
JP4, JP104 - CH2 alarm enable / ignore
- 3-pin jumper
dot
position - Failure in CH1 will cause the 1582-14 to switch to CH2 even if CH2 is in alarm. LEDs
will correctly show CH2 alarm status
Non-dot
position - Failure in CH1 will cause the 1582-14 to switch to CH2 only if CH2 is not in alarm.
JP4, JP104 normal position - non-dot
JP9, JP109 - CH2 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 CH2.
Dot
position - presence of clock is detected after about 1 ms of positive transitions of clock from CH2.
JP9,109 normal position - Non-dot
