MODEL 1582-14 Data Switch 1.0 General 1.1 Equipment Description - The 1582-14 Data Switch has two independent switches (A and B) in a single 1 3/4” chassis. Each switch provides Auto, Manual, or Remote relay switching between CH1 and CH2 RS422 clock or data signals on pins 3 and 8 with pin 5 ground and the other pins not connected. Clock or data transitions are detected from pin 3 and a clock (or data) presence alarm is activated if transitions are lost for a set period of time.

2.4 PC Board Settings 2.4.1 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.
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.
2.5 Time Out Alarm Settings - Switches S4 (CH2, SWITCH A), S5 (CH1, SWITCH A), S104 (CH2, SWITCH B), and S105 (CH1, SWITCH B) determine the length of time after clock is removed before a loss of clock alarm is indicated. Use a small flat blade screwdriver or tuning tool to carefully adjust these switches to the desired length in 0.1 second increments (position 1 = 0.1 seconds, position 2 = 0.2 seconds, etc.). (see Figure 2.
2.6 Switch Mode Setup - The following gives the switch mode settings of the on board controls that can be changed in the field: SWITCH A JP1, JP2, JP3, JP4; S3; SWITCH B - JP101, JP102, JP103, JP104, S103 (Section 2.3, Figure 2.3). All shown with external alarm = ground. 1) CH1 Prime Mode - Switches from CH1 to the CH2 only if CH1 alarms and CH2 is good.
2.8 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.
