Figure 10. RS-485 Two-Wire Connection
No jumpers are required to bridge the transmit and receive lines in two-wire mode.
RS-232 Connection
Connect to RS-232 using the RJ45 jack on the front Base module, using the supplied
RJ45 male to serial (DB9 female) cable. Note: RTS is reserved for use by the
configuration software only. Asserting RTS during normal operation will result in a
communication failure. Disable RTS if your hardware supports it.
Note: A standard RJ45 to serial (DB9) cable will not work, use only the one supplied
Power Supply Requirements
Zlinx 485 systems can be powered from 10 to 30 VDC power sources. No supply is
included since the power rating of the supply will depend on the total power requirements
of all modules used in the system.
Appendix A contains a listing of power requirements for all Zlinx 485 modules.
Mounting Hardware
Zlinx 485 modules can be DIN rail mounted. The DIN mounting clip and spring is
included on each module.
