DA connected to RXDA and TXDB connected to RXDB for use with half duplex single pair communications the normal result would be that the UART would receive all of its own transmitted data This is a nuisance because software must delete the unwanted received characters This can be avoided by setting port in half duplex mode This disable the receiver interface chip when transmitting so transmitted characters are not seen by the receiver Jumper W2 controls half duplex mode on channel 0 jumper W4 controls half duplex mode on channel 1 jumper W9 controls half duplex mode on channel 2 and jumper W11 controls half duplex mode on channel 3 Placing the jumpers in the left hand position enables the half duplex mode Placing the jumper in the right hand position enables normal full duplex operation Page 10 4163 USER S MANUAL CONFIGURATION RS 422 TERMINATION JUMPERS 4 7 9 Pes 4183 11 RS 422 HALF DUPLEX MODE JUMPERS 4163 USER S MANUAL CONFIGURATION

11. N To connect the 4163 to an RS 485 bus you need to connect RXDA to TXDA and RXDB to TXDB The RS 485 I O pair is then connected to TXDA and TXDB You would normally enable the half duplex option for channels being used for RS 485 RS 422 RS 485 DRIVER ENABLE The 4163 has the ability to control the driver enable for RS 485 and multipoint RS 422 links RS 422 and RS 485 driver enable is controlled by DTR When DTR is set to the active state a 1 in the modem control register the driver is enabled when set to the inactive state a 0 in the modem control register the driver is tri stated The OXPCI954 UART also has the ability to control the driver so that the driver is enabled automatically when data is transmitted and disabled when through transmitting Page 20 4163 USER S MANUAL REFERENCE INFORMATION SPECIFICATIONS MIN MAX UNIT POWER SUPPLY Voltage 4 5 5 5 Supply current RS 232 only 70 mA Supply current RS 232 RS422 150 mA Supply current RS422 only 250 mA ENVIRONMENTAL Operating temperature range I version 40 85 C C version 0 70 C Relative humidity 0 90 Percent Non condensing Page 21
