A APPENDIX – AUX Serial Port Connection
The auxiliary serial port can communicate via RS232, RS422 or RS485. The mode is
configured via jumpers internal to the JNIOR. The default communication setting is
RS232 and so no action should be required. However, if you are having problems,
the following information is provided.
To set the communication mode, you must remove the four screws on the JNIOR and
remove the lid. The jumpers are located in the upper right corner. Pin number 1 is
closest to the outside of the box. The internal jumper settings are as follows:
Mode J15 J16 J17
RS-485 2-Wire Half Duplex – Terminated 1 – 2 1 – 2 1 – 2
RS-485 2-Wire Half Duplex – Not Terminated 1 – 2 1 – 2 2 – 3
RS-422/RS-485 4-Wire Terminated 2 – 3 2 – 3 1 – 2
RS-422/RS-485 4-Wire Not Terminated 2 – 3 2 – 3 2 – 3
RS-232 (default setting since January 1, 2008) 2 – 3 2 – 3 2 – 3
Aux Serial with 5-Pole Connector
The JNIOR Model 310 with a catalog number of JNR-100-003A has a 5 pole connector
for the Auxiliary Serial port. A serial cable with an open end is required so that the
cables can be connected. Only the send, receive and ground wires are needed. These are
pins 2, 3 and 5 on the DB9 connector. The following information is provided to make the
custom cable. The serial device is connected to the 5-pin connector as follows, where pin
1 is closest to the center of the JNIOR box:
Pin 1 – Ground
Pin 2 – RS232 (TX) / RS485 (TX-)
Pin 3 – RS232 (RTS) / RS485 (TX+)
Pin 4 – RS232 (RX) / RS485 (RX-)
Pin 5 – RS232 (CTS) / RS485 (RX+)
Aux Serial with DB9 Connector
The JNIOR Model 310 with a catalog number of JNR-100-003B and the JNIOR Model
312 with a catalog number of JNR-200-003B both have a female DB9 connector for the
Auxiliary Serial port. A straight through serial cable is required.
