MODEL 21582-70L Switch 1.0 General 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.

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.

2.3 Setup Instructions a. b. c. d. Set the on board controls as desired (Tables 2.2, 2.3, Figure 2.3). Install the 1582-70 in the equipment rack. Connect RF to the BNC connectors (J1 - J3, J4 - J6)). Connect to signals on the MONITORS AND CONTROLS connector, J7, as desired (see Figure 2.0, Table 2.0) e. Connect power via two power cords f. Manually switch between channels 1 and 2 and be sure switching occurs g. Switch to AUTO. Alarm channel 1 and note that automatic switching occurs.
3.0 Environmental Use Information 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.
4.0 Theory of Operation Cross Technologies 1582-70L Switch 4.1 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.
4.2.2 "CH1" As Primary Source Operation (JP1 2-3 and JP3 2-3) With the jumpers in this configuration the Auto Latch will always select "CH1" unless "CH1" is alarmed and "CH2" is not alarmed. This is accomplished by grounding the reset on the Auto Latch via JP1 and JP3. 4.2.3 Restore "CH1" On Reset (JP1 2-3 and JP3 1-2) This configuration will cause the switch to remain in the "Select CH2" state, after an "CH1" is alarmed and "CH2" is not alarmed condition occurs, until a remote or manual reset is actuated.
4.2.5 Initial Channel Select (ICS) or Auto Latch Tracking S4 provides the user with a method to force the Auto Latch to follow the remote or manual inputs. This feature eliminates unnecessary switching when moving between either Manual or Remote operation back to Auto operation. The Remote and Manual logic signal are routed to inputs on the Auto Latch that cause it to "track" the RF switch state. This feature can be enabled or disabled by opening or closing the switches on S4.
