To update to a new software version, you need a PC/Windows computer with an RS232
port, an RS232 cable and an RS232 adapter. If you don't have an RS232 adapter, you
can order one from VLSI Solution or build it yourself: the adapter consists of one single
MAX3232 compatible RS232 signal converter.
Figure 5.1: How to Connect an RS232 Adapter to VLSI's VoIP Board
If loading a program to VLSI Solution's example boards, connect the adaptor cable to
the main board as shown in Figure 5.1. The black thread should go to pin 1. If you use
a custom board, you will have to use your own adapter.
