Ethernet Management Port
The LB532A-M offers a 10/100 Ethernet port to view the current DIP switch settings
via Telnet sessions. The Ethernet interface default IP address is 192.168.200.1. Log
into the LB532A-M management port using the password superuser.
Through the Ethernet management port, the following variables can be configured
or monitored:
• status: Shows the general configuration and status of the unit
• info: Shows system information
• upgrade: Enables the system upgrade prompt
Line Status Command. The status command shows the following line status informa-
tion: sync state, link state, link speed, error counters, line condition, noise margin, and
test mode status.
The following status information is available through the Command Line Interface:
• sync state: Out of Sync, Acquiring Sync, In Sync, or Losing Sync
• link state: In Progress, Success, Deactivated, or Idle
NOTE: Link State vs. Sync State—The Link State describes whether the line is train-
ing (in progress), linked (success), deactivated (we don’t have an option to deactivate
the modem, so the user should not see this), or idle.
NOTE: The Sync State describes whether no sync words have been found (out of
sync), there are no sync word errors (in sync), or whether we are transitioning from out
of sync to in sync (acquiring sync) or vice versa (losing sync). Typically, when the link
is training, the sync state goes from out of sync to acquiring sync to in sync.

3. INSTALLATION
Once the LB532A-M is properly configured, it is ready to connect to the line interface
and to the power source. This section explains how to make these connections.
Figure 3. LB532A-M front panel connectors
3.1 CONNECTING THE INTERFACE
The LB532A-M supports communication between two DTE devices using 24 AWG
(0.5 mm) wire up to:
• 18,000 feet (3.4 miles or 5.48 km) at 192 kbps per hop
• 11,000 feet (2.2 miles or 3.5 km) at 5696 kbps per hop
Two things are essential:
1. These units work in pairs with any LB532A-L, LB532A-R, LB512A-L or LB512A-
R model. Every local line port should connect to a remote line port.

724-746-5500 | blackbox.com Page 17
Installation
Figure 4. Local to remote connection
2. To function properly, the LB532A-M needs one twisted pair of metallic wire. This
twisted pair must be unconditioned, dry, metallic wire, between 19 (0.9mm) and
26 AWG (0.4mm) (the higher number gauges will limit distance). Standard dial-
up telephone circuits, or leased circuits that run through signal equalization
equipment, or standard, flat modular telephone type cable, are not acceptable.
The RJ-45 line connector on the LB532A-M’s twisted pair interface is polarity insensi-
tive and is wired for a two-wire interface.
3.2 CONNECTING THE ETHERNET INTERFACE
This section describes how to connect the Ethernet ports to your network equipment.
The RJ-45 ports labeled Ethernet are the Auto-MDIX 10/100Base-T interface. These
ports are designed to connect directly to a 10/100Base-T device or network. You may
connect these ports to a hub or PC using a straight through or crossover cable that is
up to 328 ft long.
The interconnecting cables shall be acceptable
for external use and shall be rated for the
proper application with respect to voltage, cur-
rent, anticipated temperature, flammability, and
mechanical serviceability.
