Using Landline Communications
10-4
Table 10-2 lists the direct communications capabilities via the RS 232 cable. HP
recommends that you replace the serial cable on a regular basis based on used rate or
at any time communications problems arise through the RS232 port, especially for
units used outside of North America and the UK.
The internal modem will not work with a digital phone system or a digital Public
Branch Exchange (PBX).
Figure 10-2 illustrates a standard landline connection using the internal modem.
Figure 10-3 shows the HP CodeMaster 100 connecting to a landline connection
using an external modem.
