CHAPTER 4: Operation

4.2 Remote Switching

When you do remote switching, keep these things in mind:

•The knob on the Switch’s front panel must be in the “REMOTE” position.

•The Switch interprets any voltage more negative than approximately 1.4 volts as a “low” and any voltage more positive than approximately 1.4 volts as a “high” (see the “Remote Input Logic Levels” spec in Chapter 1 for maximum and minimum switching points).

•In dry-contact applications, the Switch will read a “low” when the contact is closed and a “high” when the contact is open.

•The maximum allowed voltage on the remote-input leads is ±15 volts.

4.2.1 ABC AND ABCDE SWITCHES (SW980 AND SW982 UNITS)

To test the remote-switching capability of your Local/Remote Electronic Switch system, you must first turn the knob on the Switch’s front panel to “REMOTE.” Now have the common device send data to, or receive data from, branch devices “A” and “B” (and, for SW982 units, “D” and “E”), one after the other. Switch between branch devices by sending “high” and “low” electric signals to the Switch through its RJ-45 connector or its internal 4-position terminal block. See Tables 4-1and 4-2on pages 20 and 21 for pinouts and signal levels; see Figure 4-1on page 17 for basic illustrations of how the Switches function.

4.2.2X SWITCHES (SW981 UNITS)

To test the remote-switching capability of your Local/Remote Electronic Switch system, you must first turn the knob on the Switch’s front panel to “REMOTE.” Now have each source device (“A” and “B”) send data to each destination device (“AA” and “BB”), one after the other. Switch between data pathways by sending “high” and “low” electric signals to the Switch through its RJ-45 connector or its internal 4-position terminal block. See Table 4-1on the next page for pinouts and signal levels; see Figure 4-2on the previous page for a basic illustration of how the Switch functions.
