Figure 4: Wiring Diagram for DB-15 I/O connector
Use shielded 18-22 AWG (0.82-0.33 mm2) twisted pair wire for all I/O connections. To ensure compliance to EN 61010
requirements, a shielded cable is required for these connections and the shield must be terminated to the Ground
( ) terminal on the back panel.
For operation on RS-485, 2-wire, half-duplex bus, attach the RS-485 (+) to (+) and the RS-485 (-) to (-). If available,
make a third connection to the RS-485 network common to RTN. Connect the shield wire from the cable to SHD
terminal. For operation on RS-232, connect RS-232 (TXD) to (+), RS-232 (RXD) to (-), and RS-232 (GND) to RTN.
Connect the cable shield wire to SHD terminal.
Note:
The default configuration of the two serial ports as shipped is shown below:
