Local/Radio Connections
NOTE:
Connections to radios differ from connections for remote operation; therefore connections are discussed
separately.
Jumper Positions
An example of the jumper positions are shown in Figure 82. In the figure, jumper 14 (J14) is shown in position A, jumper 3
(J3) is shown in position B, and jumper 23 (J23) has been placed on the center pin indicating the jumper is in the NULL
position.
To adjust the position of a jumper, do the following:
1.
Remove power from the IP-223 unit.
CAUTION: Failure to remove power may cause damage to the IP-223.
2.
Remove the six (6) screws from the case top.
