Connecting to a Serial Interface
The ARN supports up to five serial interfaces. You can connect
• Up to three, 44-pin serial cables to an ARN that contains an Ethernet/tri-serial,
Token Ring/tri-serial, or Tri-Serial expansion module
• One, 44-pin serial cable to each Serial adapter module (the ARN can support
two)
To connect to a serial interface:
1. Locate the RS-232, RS-422, RS-530, V.28, V.35, or X.21 interface cable.
See the Cable Guide for Routers and BNX Platforms.
2. Connect the cable to a serial interface.
The serial interfaces on an ARN expansion module are labeled COM3,
COM4, or COM5 (
Figure 1-9 ).
Figure 1-9. Connecting Serial Cables to an Expansion Module
Note: The Cable Guide for Routers and BNX Platforms refers to serial cables
that transmit synchronous data as “synchronous” cables.
