Features Overview The ANC-6090 adapter converts the serial port RS-232C level transmit and receive signals on an IBM compatible personal computer (Pc), or any device with an RS-232C type interface, into bipolar-current RS-422 or RS-485 compatible signals. The adapter interface voltage levels produced meet the EIA-232, TIA-232, RS-422 and RS-485 signals. -

Pc. Be sure to look at the label on the adapter to identify and insure that the proper DB9 is plugged into the Pc’s serial jack. The ANC-6090 has female DB9s at both ends. The user should screw the 2 mounting screws into the serial port’s hex nuts for permanent installations to assure good long-term connection. -

DB-9 connector. Transmit Control Enable - JP1 For single adapter 4-wire setups where the ANC-6090 is controlling one piece of equipment, JP1 can be set in the horizontal position, as shipped, so that the transmit data RS-422/485 driver lines are always asserted. For battery powered applications, it may be desirable to turn off the transmit drivers to save current when there is no data being transmitted using the RTS control line. -

For installation cable lengths greater than 150 feet, resister termination across the remote receive pair end of the cable may be necessary. The ANC-6090 has a ½W 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. -

RS-422/485 side of the adapter. The configuration as shipped from Antona is set for ‘master’. This configuration is for the adapter acting as a controller to multimedia type equipment with an RS-422 SMPTE interface. -

For other interfaces, the user hand-wires a 9-pin cable assembly from the RS-422/485 piece of equipment to the Antona adapter with the appropriate pin to signal interface. The only difference between the ‘master’ and ‘server’ (slave) version is the jumper positions of JP5 and JP6 within the adapter. -

Generally, this requires externally powering the Antona adapter, but for short cable runs to non-terminated equipment operating at medium baud rates (like 9600 or less) an external power supply may not be needed. The designer should use twisted pair wire with a impedance of 100 to 120 ohms. -

3 – typical 2-wire RS-485 interface The photo below (photo 2) shows a typical transmission and reception over an RS-485 2-wire interface. The top trace shows the data transmitted from the ANC-6090 with a scope probe on the TX+/RC+ combined line. The 2 group of noisy looking characters is the response received from a remote device about 4 ms after the last character is sent through the ANC-6090. -

Loopback Test You can verify that the Antona adapter is working by doing a simple loopback test using a male DB9 connector with a wire connection from pin 3 to 7 and pin 8 to 2. You can also add external power by soldering a 9v battery clip between pin 1 (ground) and pin9 (+V). -

(under 150 feet) in an electrically ‘clean’ environment (like an office) then you probably do not need the cable to be terminated. If on the other hand you are using the ANC-6090 to interface with 2 or more RS-485 devices in an industrial environment with hundreds of feet of cable runs –... -
