Introduction
40 MB of disk space for the ValveLink software. Additional space is required for the number of instruments you configure and the amount of diagnostic data you save. SVGA or better monitor, (800 x 600 pixel screen resolution) Parallel printer port Hardlock for VL2000 Series ValveLink software; required for installation only For Type VL2021f or VL2021fH 16-bit ISA slot for NI-FBUS board or PCMCIA compatible computer for NI-FBUS card For VL2005H, VL2021H, VL2021fH, VL2031H, or VL2041H Nine pin serial port for connecting HART modem or HART multiplexer network. Second serial port required for communicating on second multiplexer network or on a Modbus network. HART multiplexer and RS232-to-RS485 converter, if the ValveLink software has multiplexer capability and you are planning to communicate to the instruments over a HART multiplexer network HART modem, if you are not going to communicate with HART instruments over a HART multiplexer network When using a HART modem, the computer RS232 port must have at least 7.0 Vdc on the Data Terminal Ready (DTR) line, pin 20, with a 1000 Ohm load to ground. For HART instruments (DVC5000 Series), ValveLink software communicates using a HART modem or HART multiplexers. For FOUNDATION fieldbus instruments (DVC5000f Series), ValveLink software communicates over an H1 segment. These devices must be connected to the PC and have access to the field instrument wiring. ValveLink software works with: DVC5000 Series digital valve controllers DVC5000f Series digital valve controllers VL2000 Series
