3. The ANC 6090 has 2W 120 ohm termination resister built in that can be placed across the receive wire pair by setting jumper 4 JP4 located over the transmit receive setting jumpers As described above an external DC power source may be feed into pin 9 on the RS 422 485 connector to supply the additional current that the adapter may need when terminating resisters are installed on the receive transmit wire pairs Note that some multimedia equipment have internally 8 connected circuitry for 120 ohm resister termination If So then even if the separation distance 15 less than 150 feet it may be necessary to provide an external source of DC Some equipment also allows the user to disconnect the internal termination network for short cable runs See Appendix C the upper middle of the schematic for the location of JP4 Transmit Receive Pin Reverse Jumpers JP5 JP6 These two jumper sets designated JP5 and JP6 on the circuit board and schematic allow the designer to swap the transmit and receive pairs on the RS 422 485 side of the adapter The configuration as shipped from Antona 15 set for master This configuration 15 for the adapter acting as a controller to multimedia type equipment with RS 422 SMPTE interface Figure shows the jumper locations from component side of the circuit board The user may move all four jumper shunts on the component side of the card from the horizontal controller configuration to the vert
