1582-225L2 1:1 Switch, DC-2.5 GHz, 2PDT, M&C Monitor and Channel Select
1.0 General
The 1582-225L2 Dual 1:1 Switch provides two 2PDT switch pairs ( SWITCH 1 and SWITCH 2). Each
switch independently provides Auto, Manual or Remote (M&C) latched relay switching between PRIMARY
and BACK-UP, DC - 2.5 GHz RF signals. The M&C provides monitoring of all parameters, Switch and History
Reset, and Channel Selection (when in Auto mode only). Alarm conditions on PRIMARY and BACK-UP are
either a contact closure to ground or an open (selectable by a rear panel DIP switch). Auto has three modes:
Auto - PRIMARY PRIME ; The PRIMARY preferred mode - switches from PRIMARY to BACK-
UP only if PRIMARY alarms and BACK-UP is good. The unit switches back to PRIMARY when PRIMARY
is no longer in alarm or both PRIMARY and BACK-UP in alarm.
Auto - LATBACK-UP; Latch to BACK-UP mode - switches from PRIMARY to BACK-UP if
PRIMARY alarms and BACK-UP is good and stays in BACK-UP regardless of PRIMARY or BACK-UP
alarm conditions until reset to PRIMARY by the front panel Switch Reset switch or M&C command.
Auto - MIN SW; Minimum Auto switching mode - switching occurs if the active channel (set by the
front panel Manual Select switch or M&C command) alarms and the other channel is clear. It switches back if
this channel then alarms and the other is clear.
When power is lost, the current latched state remains selected. Front panel LEDs indicate PRIMARY
and BACK-UP alarms, Remote or Manual mode, and redundant power supplies on. Rear panel DIP switches set
alarm polarity (NO or NC for alarm), M&C interface, and Auto modes (PRIMARY PRIME, LATBACK-UP, or
MIN SW). The front panel switch selects the signal path in the Manual mode or selects AUTO switching. The
RS232 or RS422/485 M&C (Ethernet optional) monitors switch positions, LED and alarm status, and selects
the RF switch position (when in Auto mode only). A contact closure to ground indicates an internal fault
condition or loss of power. Connectors are BNC for RF signals and DB9 for M&C and alarm input and output
contact closures. It is powered by separately fused, 100-240 ±10% VAC redundant power supplies.

1.4 M&C Commands
The following tables summarize the commands and status queries applicable to the 1582-225L2 Switch.
*PLEASE NOTE: The two character {aa} prefix, shown in the table below, is present ONLY when RS485 is selected.
Table 2.0 Model 1582-225L2 - M&C Remote Commands
Will (remotely) set Switch 2 to BACK-UP. The unit will ignore this command if the switch
is in manual mode. The unit will reply with the '>' character if the command is
successfully processed.
example: {CS2}
3. The switch position is manually selected via the front panel Manual Select toggle

2.4 Operation
1. Set the on board controls as desired (Tables 2.0, 2.1, Figure 2.3).
2. Install the 1582-225L2 in the equipment rack.
3. Connect RF to the BNC connectors (J1, J2, J3, J4, J5, J6, J7, J8, J9, J10, J11, J12).
4. Connect to signals on the MONITORS AND CONTROLS (DB9 connectors), J16A & J16B,
as desired (see Figure 2.2, Table 2.1).
5. Connect power via two power cords to AC1 and AC2.
6. Manually switch between PRIMARY and BACK-UP and be sure switching occurs.
Check SW1 and SW2.
7. Switch to AUTO Alarm Switch 1 and note that automatic switching occurs. Remove alarm
to CHI and note that the output switches as desired. Push RESET if in LATCH mode.
Repeat for CH2.

2.5 Auto Switching Description
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 1582-225L2 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 1582-225L2, 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 75ΩBNC, female and IF-L connectors are 75ΩBNC, female. Contact closure inputs are via
barrier strip. Dual power supplies provide redundant power to the 1582-225L2. The chassis is a 1 3/4” rack
mount.

A.Rack-Mounting - To mount this equipment in a rack, please refer to the installation instructions
located in the user manual furnished by the manufacturer of your equipment rack.
B. Mechanical Loading - Mounting of equipment in a rack should be such that a hazardous condition
does not exist due to uneven weight distribution.
C.Elevated Operating Ambient Temperature - If installed in a closed or multi-unit rack assembly,
the operating ambient temperature of the rack may be greater than room ambient temperature.
Therefore, consideration should be given to Tmra (Maximum Recommended Ambient Temperature).
D. Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow
required for safe operation of the equipment is not compromised. Additional space between units
may be required.
E. Circuit Overloading - Consideration should be given to the connection of the equipment to the supply
circuit and the effect that overloading of circuits could have on over current protection and supply wiring.
Appropriate consideration of equipment name plate rating should be used, when addressing this concern.
F. Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained.
Particular attention should be given to supply connections other than direct connection to the
Branch (use of power strips).
G. Top Cover - There are no serviceable parts inside the product so, the Top Cover should not be removed.
If the Top Cover is removed the ground strap and associated screw MUST BE REINSTALLED
prior to Top Cover screw replacement. FAILURE TO DO this may cause INGRESS and/or EGRESS
emission problems.
