IOLAN SDG1 LA/LE Hardware Installation Guide
Terminating 485/Full/Half and 422 Mode
When in 485/full/half or 422 mode, termination is not necessary unless the IOLAN’s are
the end points.
Remove the screws from the case and gently lift the top section of the case from the
bottom section. Locate SW 5 on the board.
To set RX Termination on port 1: Set DIP switch #1 ON (used for 422/485 half duplex)
To set TX Termination on port 1: Set DIP switch #2 ON (used for 485 full duplex).
Note: For EIA-232 these switches must be in the OFF position (default)

The 10/100/1000BaseT(X) port is located on the back of the IOLAN SDG1 LA/LE. This
Ethernet port will automatically adjust depending on the type of Ethernet cable used

connected to the port.
Requirements:
• Cat 5 UTP or STP, Cat 5e cables
• 24-22 AWG (0.20mm
