Ethernet
Port
The Ethernet port allows direct connections to a PC or network for communication
over UDP. The BH32 supports Power over Ethernet (PoE) technology using the
802.3AF PD standard. Use of Cat 5 (or greater) Ethernet cable recommended. The
BH32 can connect directly to a PC, an RZ device, or a network. If connecting
directly to an RZ device, a crossover Ethernet cable is required. See “BH32 Circuit
Design” on page 17-26, for more information on communicating with the BH32.
RS
232
The BH32 can communicate with other devices over a serial port. See “BH32 Circuit
Design” on page 17-26, for more information.

E
Switch
This toggle switch determines whether the BH32 serial port is in master or slave
mode. This selects which wires on the BH32 serial port will be send and which will
be receive.
BH32
Configuration
This section discusses configuring the BH32 networking communication and hardware
interfaces. See “RZ-UDP Communications Interface” on page 1-51, for more
information on the basics of networking and the various protocols.
Initialization
The BH32 will attempt to locate a DHCP server that will dynamically assign an IP
address to the device.
If no DHCP server responds, the following static IP configuration is used:
IP Address:
10.1.0.101
IP Mask:
255.0.0.0
Gateway: 10.1.0.1
In either case, dynamic or static, the interface IP address is associated with a
unique NetBIOS name set by TDT.
NetBIOS
Name
All BH32 devices will use this standard NetBIOS Name structure:
TDT_BHC_32_XXXX
XXXX = last 4 digits of the BH32 device serial number.
For Example:
A BH32 with a serial number of 1234 uses a NetBIOS name of:
TDT_BHC_32_1234.
Although a default NetBIOS name is assigned, the name can be changed using the
BH32 Web Interface. See below for more information.
Note:
When connecting the BH32, be sure the network mask is set to a Class C or
smaller network. A Class A network mask (255.0.0.0) will disable NetBIOS naming
