INSTRUCTION MANUAL 1582-70L SWITCH
1.1 Equipment Description - The 1582-70L Switch provides AUTO or Manual latched relay switching
between CH1 and CH2 RF signals.(DC - 1.5 GHz). Automatic control determines switch routing by monitoring
alarm inputs on two channels (CH1, CH2) and selecting the initial source. Local and remote control of RF sources
is also provided. Latching relays allow the switch to remain in its "current" state independent of power loss.
The 1582-70L detects an external alarm condition on CH1 and CH2 by either a contact closure to ground or an
open (selectable). Switching logic can be selected as follows:
1) CH1 Prime Mode - Switches from CH1 to CH2 only if CH1 alarms and CH2 is good Switches back
to CH1 when it is no longer in alarm or when both CH1 and CH2 are in alarm
2) Latch to CH2 Mode - Switches to CH2 if CH1 alarms and CH2 is good. Latches to CH2. Push
Manual Reset or ground Remote Reset pin to return to CH1 if it has no alarm or both CH1 and CH2
are in alarm.
3) Minimum AUTO switching, Initial Channel Select (ICS) Mode - Switch stays on channel last
selected by Manual or Remote selection after return to AUTO. AUTO switching occurs only if current
channel alarms and the other channel is clear.
Switching is accomplished using latching relays so if power is removed from the 1582-70L, CH1 and CH2 RF will
continue to go to the output selected prior to power loss and will remain there when power is applied assuming no
change in alarm status from when power was lost. The channels can be manually switched by the front panel Manual
Select switch. If operating in the ICS mode, the last channel manually selected (CH1 or CH2) will be the initial
channel when returning the Manual Select switch to AUTO. External REMOTE contact closures can force selection
of CH1 or CH2 when the Manual Select switch is in the AUTO position independent of the alarm conditions of CH1
or CH2. Front panel LEDs indicate alarms, alarm history (prior occurrence of alarms which have now cleared),
switch conditions for CH1 and CH2, REMOTE or MANUAL operation and presence of power.
RF connectors are BNC, female. Contact closure inputs are via barrier strip. Dual power supplies provide redundant
power to the 1582-70L. The chassis is a 1 3/4” rack mount.

TABLE 2.2 PC BOARD SETTINGS
NOTE: Dot position means jumper goes from pins 1-2; non-dot means jumper goes from pins 2-3
JP1 - 3-pin jumper - 3-pin jumper that works with JP3
In the dotted position when channel 1 alarms the 1582-70 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.
JP1 normal position - non-dotted and operates in conjunction with JP3 as noted below.
JP2 - Input alarm condition 3-pin jumper
In the dotted position open is normal, ground is alarm
In the non-dot position ground is normal, open is an alarm.
JP2 normal position - dot
JP3 - 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 1582-70 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 J7, and then it switches to channel 1. (If channel 1 alarms are cleared ). If in the ICS
mode and originally set to CH2 the 1582-70 will not switch if CH2 alarms. Only the RESET functions (front
panel pushbutton or J7 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 1582-70 switches to channel 2
until the alarm on channel 1 clears and then the 1582-70 switches back to channel 1 automatically.
JP3 normally position - dot .
JP4 - CH2 alarm enable / ignore - 3-pin jumper
Dotted position - Failure in CH1 will cause the 1582-70 to switch to CH2 even if CH2 is in alarm. LEDs will
correctly show CH2 alarm status
Non-dotted position - Failure in CH1 will cause the 1582-70 to switch to CH2 only if CH2 is not in alarm.
JP4 Normal position - non-dot
SW4 - Initial Channel Select (ICS) Mode- 4-position DIP switch Selects the Initial Channel Select mode when
JP1,2,3 in Dot and JP4 in Non-dot.
S4 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 1582-70 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..
S4 positions 1,2,3,4 to OFF - ICS is disabled (Minimum Auto switching, Return to Last State Mode)
The 1582-70 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.
S4 normal position - 1,2,3,4 to ON

3.0 Theory of Operation Cross Technologies 1582-70L Switch
3.1 Introduction - The 1582-70L Switch provides automatic and manual control of RF sources or loads
depending on the user's application. Automatic control is facilitated by monitoring of alarm inputs and selecting the
initial RF source. Local and remote control of RF sources is also provided. LED indicators are provided for Alarm
and Alarm History ("CH1" and "CH2"), Power ("CH1" and "CH2"), Remote, Manual as well as "CH1" and "CH2"
Select. Latching relays are an option that allows the switch to remain in its "current" state independent of
power loss.
3.2 Circuit Description (Refer to Switch Matrix)
3.2.1 Auto Operation
Assume that the jumper and switch settings are configured for "Normal Auto Switch Setting" as shown at the
bottom of the matrix unless otherwise specified..
Alarm inputs "1" and "2" are monitored by the "Auto Latch" (U4). This latch will only change states when the
selected source is in an alarm state and the unselected source is in a not alarmed state. The alarm inputs first pass
through U1A and U1B where they are either inverted (Low = Alarm - JP1 1-2) or not inverted (High = Alarm - JP1
2-3). The output of U1A (pin 3) is the Alarm 1 status where High = Alarm. The output of U1B (pin 6) is the Alarm
2 status where High = Alarm. These outputs then go to inputs on U6 and U4. A logic Low on the output of U4A
(pin 3) = "1" is alarmed AND "2" is not alarmed. In this case the Auto Latch (U4) will be set to select "CH2". A
logic Low on the output of U4B (pin 6) = "1" is not alarmed AND "2" is alarmed. In this case the Auto Latch (U4)
will be set to select "A". If both alarm inputs are alarmed or both alarm inputs are not alarmed, the Auto Latch will
not be affected. The output of the Auto Latch (U4 - pin 6) determines which RF source will be selected (in auto
mode only) where a logic High = Select "CH2".
The Auto Latch logic then passes through the remote control circuitry, which without remote control asserted, will
not affect the logic levels. After the remote circuitry the logic signal passes through the manual control circuitry,
which without manual control asserted, will not affect the logic levels. After the manual control circuitry, the logic is
either applied directly to the relay drivers (High = Select "CH2") for non-latching relays or is routed through U9A
and U10 for latching relay versions.
For models with latching relays the logic signal first passes through U9A that provides a relay pulse to ensure that
the relays will all be set to the same state on power-up. R28 and C7 provide a pulse to the dual "one-shot" (U10)
The outputs of U10 provide the relay set (U10 pin 6) and reset (U10 pin 10) pulses for the latching relays. A "Set"
pulse selects "CH1" and a reset pulse selects "CH2". U12A and U12B provide a "lock out" that eliminates the
possibility of a set and reset pulse occurring simultaneously by "resetting" each other's "one-shot" during a set or
reset pulse.
