RF Unit Jumper Information

JP1501 (JP1): Determine the output supply voltage at pin 8 of DSUB 9-pin Accessory Connector. Close: +5.0 V (Maximum 100 mA)

Open: No Action

JP1502 (JP2): Determine the output supply voltage at pin 8 of DSUB 9-pin Accessory Connector. Close: +13.8 V (Maximum 100 mA)

Open: No Action

JP1503 (JP3): Determine the Rx discriminator output characteristic at pin 2 of DSUB 9-pin Accessory Connec- tor.

Close: Flat 10 Hz to 3.0 kHz (140 mVrms / STD deviation with 600 ohm termination)

Open: No Action

JP1504 (JP4): Determine the Rx discriminator output characteristic at pin 2 of DSUB 9-pin Accessory Connec- tor.

Close: Filtered 300 Hz to 3.0 kHz (70 mVrms / STD deviation with 600 ohm termination)

Open: No Action

JP1505 (JP5): No Action (Spare Jumper).

JP1506 (JP6): Define whether the TX Data Input at pin 3 of DSUB 9-pin Accessory Connector shall be "on" or "off" according to the external PTT Input signal signal (pin 7 of DSUB 9-pin Accessory Connec- tor).

Close: on (Enabled)

Open: off (Disabled)

JP1507 (JP7): Determine the TX Data Input level at pin 3 of DSUB 9-pin Accessory Connector. Close: 400 mVrms / STD deviation with 600 ohm termination

Open: 40 mVrms / STD deviation with 600 ohm termination

JP1508 (JP8): Define whether the Transceiver's power shall be "on" or "off" according to the Ignition Signal Input (pin 9 of DSUB 9-pin Accessory Connector).

Close: Turn the transceiver on when the Ignition Signal Input (pin 9 of DSUB 9-pin Accessory Connector) is turned to "High" while the VOL/PWR knob is set to the "ON" position (out of the click-stop position).

Open: No Action
