Note that a null-modem adapter/connection is not required.
5.2.1 Determining the Machine Number Each unit must be identified by a unique machine number (MACH #). Determine the machine number according to the following table. When using a single unit, set the unit to Machine # 1. A master unit must be Machine #1. When connecting more than one VS-44FO, set a different Machine # for each unit. The units do not have to be numbered sequentially but each unit must have a unique machine number.
Figure 5: DIP-Switch Settings DIPS Function Description RS-485 TERM RS-485 line termination OFF for no RS-485 line termination ON for RS-485 120 line termination PROG Firmware update Set ON only to update device firmware MACH # 1, 2, 3, 4 Self Address Sets the MACHINE # (see Section 5.3.1) The RS-485 TERM DIP-switch is used only when the RS-485 port is connected (see Section 5.3). The first and last units on the RS-485 line (for example, the controller and the last VS-44FO) must be terminated.
5.3.1 Setting the Machine Number Switches To set the MACH # DIP-switches, as shown in Section 5.2.2: For a master machine, assign MACH #1 with the address 0 (0000) or 1 (0001) set in the DIP-switches For the slave units, assign a unique MACH # from 2 to 15 for each VS-44FO slave. The units do not have to be sequentially numbered but they must have unique addresses 5.3.2 Setting the Line Termination To ensure correct operation, the RS-485 line must be terminated at both ends.
Note: When turning the machine ON, the last stored setup is shown in the 7-segment display. 5.5 Connecting the Ethernet Port You can connect the VS-44FO over the Ethernet in the following ways: For direct connection to the PC, use a crossover cable (see Section 5.5.1) For connection using a network hub or network router, use a straight-through cable (see Section 5.5.2) 5.5.
