  • Page 30 LabCon Map + Printer User Manual The controller Communication Port is RS485 and requires a similar port at the host (master) end. If, however, the host port is different (say, RS232), use appropriate protocol converter (say, RS485-RS232) for interface. For reliable noise free communication, use a pair of twisted wires inside screened cable as shown in Figure 6.5. The wire should have less than 100 ohms / km nominal DC resistance (Typically 24 AWG or thicker).
