Connecting to a Host Computer<br />
Connecting to a Host Computer<br />
The host port P32 connects the <strong>apC</strong>/<strong>8X</strong> to a host computer (see Figure 4.1).<br />
• A single <strong>apC</strong>/<strong>8X</strong> can connect to the host via an RS-232 serial<br />
connection.<br />
• Multiple <strong>apC</strong>/<strong>8X</strong>s communicate via an RS-485 chain, but the <strong>apC</strong>/<strong>8X</strong><br />
chain must communicate with the host through an RS-232 to RS-485<br />
converter.<br />

You can use modems, line drivers, or other communications devices to<br />
increase the distance between the host and the <strong>apC</strong>/<strong>8X</strong>.<br />
The following sections describe these connections:<br />
• RS-232<br />
• RS-485<br />
• Modems for dialup <strong>apC</strong>/<strong>8X</strong>s<br />
• Modems for directly connected <strong>apC</strong>/<strong>8X</strong>s<br />
