| + | It's also simple to control the Inrad filter with the ATTN switch if you don't use that function. | ||
| + | Here's what you do: | ||
| + | Skip Inrad's instructions numbered 18 through 24. | ||
| + | Set aside the cable/connector provided for J4 on the Inrad board, you | ||
| + | won't need it. | ||
| + | Take the cable/connector provided for J3 and tie the lines together, | ||
| + | then | ||
| + | add an extension so the wire will reach up to the front of the Omni, | ||
| + | plus 4 or 5". | ||
| + | Locate the 3 pin white connector labeled 18, at the left front side of | ||
| + | the Front End Board, as viewed | ||
| + | from the front of the Omni. Cut the middle wire going to the connector, | ||
| + | leaving a few inches | ||
| + | behind on the connector in case you ever want to reconnect it. This is | ||
| + | the line that goes to the Attn | ||
| + | switch. Connect the lead from Inrad J3 to the end of the line going up | ||
| + | to the front panel Attn switch. | ||
| + | Tape up the end still attached to the connector. Set S1-S4 on the Inrad | ||
| + | board to ON. | ||
| + | |||
| + | That's all. Inrad now switches in and out with the Attn switch and the | ||
| + | led shows when Inrad is switched in. | ||
| + | All Omni filter switches are unaffected. | ||
