4.6 RS-232 Communication Ports
Independent communication ports are provided for the A and B Ports of the AT1702.
A single communications port is provided on the AT1701.
The communication inputs for Channel A and Channel B (AT1702 only) connect to a controller using a standard
DB9F-to-DB9M connector “straight through” serial cable.
Note: Connection to an AT2500 uses the same DB9F to DB9M cable.
Note: Connection to a CaLan 3010 requires a DB9M to DB9M “straight through” cable as sup-
plied with the 3010. Also referred to as the “cloning” cable.
The communication Output ports allow chaining the communication link from one unit to the next using a stan
-
dard DB9F-to-DB9M connector, such that all of the multiplexers are on the same communications link.
Since AT1700 series switches may be physically separated by some distance, cable up to 100 feet or 30 meters
may be used. Depending on the environment, cable may need to be shielded for proper operation. If AT1600
series switches are combined with AT1700 series switches, an RS-232 terminator may be required for proper
operation on long cable installations. Please consult the Product Support group for these special installations.
4.7 Web Browser Interface
Once the Ethernet port is configured, the AT1700 may be connected to the network. Simply enter the IP address
in the URL address bar of your browser. The user may also make all setup and configuration changes via the
web browser interface by entering the default IP address 192.168.1.1 in the URL address bar of your browser.
The current Software version, hardware version, MAC address and serial number of the AT1700 is displayed at
the top of the webpage.
