Section 2 – Net-2000™ VCU Installation
The VCU has a 10 Mbps Ethernet interface for network communication. It can operate on a 100
Mbps LAN when connected to a 10/100 Ethernet hub or router. The default network configuration
for the VCU assumes that a DHCP server is available on the LAN to provide it with valid network
address information. If a DHCP server is not available on the LAN, static IP address information will
need to be entered via the serial port in order to access the VCU over the network.
RS-232 Serial Port
Connecting to RS-232
The RS-232 serial port located on the back of the Net-2000™- P25 VCU unit provides low level set-
up functions. The interface itself consists of a simple command/response ASCII text protocol. You
can use a terminal or terminal emulator on a personal computer to type commands at a keyboard as
your user interface.
To connect the serial interface, to a Terminal or PC plug a straight-through modem cable (see pin
outs in Table 35 RS-232 Serial Port Pin Out) into the serial port DE-9s connector and plug the other
end into your terminal (or one of the serial ports on your PC if you are using an emulator). Set the
terminal as shown in Table 2 Serial Port Terminal Set-up.
