Digital I/O Connector

The Digital I/O connector has 4 GPIO connections plus 1 Return connection. The Digital I/O supports Both Dry and Wet contacts up to 60Volts.

Dry contact is isolated from a voltage source (or “No Volt”), with an embedded relay function (NPN transistor), usually used to indicate an event. For example: open/close, alarm.
Wet contact is a contact with external power (+3.3V to +60V, max 150mA of current allowed at high voltage) applied, usually used to energize something. For example: solenoid, light.

IRM-1100-4A2T Overview

The IRM-1100-4A2T is an expansion module that can be attached to the IR1101. It offers an additional four asynchronous serial ports and two Ethernet interfaces to the IR1101. The following graphic shows the IRM-1100-4A2T.

Cisco Catalyst IR1101 Rugged Series Router Hardware Installation Guide - Product Overview [Cisco Catalyst 1101 Rugged Router] (12)

The IRM-1100-4A2T Ethernet interfaces are Layer 2 RJ45 10/100/1000 Mbps ports.

The IRM-1100-4A2T serial ports are RJ45 combo ports (RS232/RS485/RS422).

The IR1101 has two sides that expansion modules mount to. The top is called the Expansion side, and the bottom is called the Compute side. If the additional module is connected to the top, then it is referenced as the Expansion Module (EM) side. If the additional module is connected on the bottom, then it is referenced as the Compute Module (CM) side. Functionality differs depending on which side the expansion module is attached to, and how many and type of expansion modules are in use.

Router Switch Path

The switch path that is detected on the platform, is based on the type of additional module connected on the Expansion module (EM) side. Refer to the following table:


Additional Module	Switch Path
No Module Connected	IR1101-ES-5
IRM-1100-SPMI	IR1101-ES-6S
IRM-IR1100-4A2T	IR1101-ES-7G

Memory

The Cisco IR1101 uses flash memory and main memory. The flash memory contains the Cisco OS software image and the boot flash contains the ROMMON boot code. The memory includes:

4 GB DRAM (soldered down)
4 GB onboard flash memory

Reset Button

The Reset button resets the router configuration to the default configuration set by the factory. To restore the router configuration to the default configuration set by the factory, use a standard size #1 paper clip with wire gauge 0.033 inch or smaller and simultaneously press the reset button while applying power to the router.

Supported Cisco Antennas and Antenna Accessories

The IR1101 must have a Pluggable Module with antenna ports installed in order to connect antennas. The base unit does not have any wireless capabilities on its own.

The Antenna Selection and Installation chapter lists the supported Antennas and Accessories for the Cisco IR1101 with a wireless Pluggable Module. For detailed information about Cisco Antennas for the Industrial Routers, please refer to the following guide:
