Installation Considerations:
1. Determine the mounting location for the B573(s) using the following considerations:
•The B573 is designed for a 1U, 19” wide rack mount installation using the brackets and bracket
mounting screws provided, but it can also be placed on a flat surface or mounted vertically on a wall.
•It should be installed so that the front panel LCD display and buttons are easily accessible.
•The mounting location should have a 100-240VAC , 1 Amp minimum power source in the vicinity of the
B573 mounting location. If the B573 has the optional 01-9981.A1 100-240VAC power supply installed, a
6 foot AC line cord is provided.
•The B573 consumes about 4 watts (300mA @ 12VDC) when powered, therefore it does not require any
forced ventilation. But, it should be mounted in a location where the ambient temperature is 50-104 F (10-
40 C).
•The B573 communicates with the Inncom Server computer via a network connection. Therefore the B573
location must provide a connection to the same network that the Inncom Server is connected to.
2. Network connectivity considerations:
•The B573 requires a fixed (static) network IP Address. This is programmed into the B573 using the front
panel LCD display and buttons. The B573 DOES NOT support DHCP. You must coordinate with the
hotels IT department to obtain a fixed IP address for each installed B573 and program it into the B573.
•The Inncom “B573_MC.exe” program running on the Inncom Server must know the IP addresses of all
B573’s in order to connect to them. The B573 IP addresses must manually be defined in the
“B573_MC.cfg” script file located in the “C:\Inncom\Scripts” folder on the Inncom Server. If any B573 IP
address is changed, the “B573_MC.cfg” script file must be updated to match and the “B573_MC.exe”
program restarted.
•The B573 communicates with the “B573_MC.exe” program running on the Inncom Server via network
UDP Port 3008. If a network Firewall is installed to separate the network that the B573 connects to and
the network that the Inncom Server connects to, the Firewall must be configured to bi-directionally pass
UDP Port 3008 traffic. This situation is typical for an installation using a B573 “MBX” with TCT room
gateway devices installed. The B573 MBX and all TCTs are connected to the guestroom (public) network,
and the Inncom Server is connected to the hotels administrative (private) network.
•If Inncom TCT “room gateway” devices are installed, the TCT’s communicate with the installed B573
MBX router via network UDP Port 23210. This Port must be open and available on the network
connecting all TCT’s to the B573 MBX, which it typically is open by default.
3. Room device connectivity considerations:
•The B573 configured as an “MBX TCT Router” can support virtually an unlimited number of TCT room
gateway connections.
However, the B573 configured as an “FLN5 RS-485 Floor Bridge” can only support a maximum of 100
room gateway connections (50 on COM_A, 50 on COM_B). This limitation must be considered when
deciding what rooms connect to what B573 FLN5 RS-485 bridge. Note that “room gateway connection”
refers to the termination of the RS-485 wiring pair at a particular Inncom device (ie E528, B485,
X529,etc). For instance, if a hotel has an E528 and a K592 Lock Gateway installed in each room, this
counts as 2 RS-485 terminations and you would be limited to 50 total “room” connections (100 total
devices).
Typical B573 Installation Steps:
1. Install the B573 hardware.
2. Connect communication wiring to the B573.
3. Apply power to the B573.
4. Obtain and set the IP Address and Subnet into the B573.
5. Set/verify the “TCTPort Offset” in the B573 MBX (only if property has a single B573 MBX with TCTs).
6. Configure and save the “B573_MC.cfg” script file to contain the IP addresses of all B573(s).
7. Configure and save the “WinP5PT.p5s” script file to tell WinP5PT it will “locally” connect to the
“B573_MC.exe” program (they both run on the same Inncom Server computer).
8. Start (or Re-Start) “B573_MC.exe” and “WinP5PT.exe” programs and verify operation.
