TSAT 3000 - Telemetry and data transfer via SATellite
TSAT 3000 Configuration Parameter Description, January 2013 Page 88 of 124
Configure Connection between HUBs
One or more (redundant) connections may be defined between the Slave- and Master-HUB.
You do this by connecting SERVICE ports together. (The same kind of communication link is
used between Main-HUBs in a Redundant Network configuration) Some examples may clarify:
• Connect with TCP/IP.
Normally, PORT [4] is SERVICE, and is using SOCKET [1]. This is normally a TSAT_NMS
Socket, using TCP/IP and Listening at local IP-port 4000. This Socket is normally used to
connect the NMS to TSAT 3000 Main-Unit, but may also be used to establish connections
between TSAT 3000 Main-Units.
Configure a new Client Socket connection on the Slave-HUB:
MIB Parameter MIB Value Description
PORT_MAX_PORTS 5 (or higher) You probably have to define more Ports.
PORT_TYPE [5] 2 – SERVICE
PORT_USE_SOCKET [5] 2
PORT_USE_COM [5] 0
PORT [5] is SERVICE,
and is using SOCKET [2]
SOCK_TYPE [2] 2 – TSAT-NMS
SOCK_PROTOCOL [2] 0 – TCP/IP
SOCK_ADDRESS [2] <Master-HUB’s IP Address>
SOCK_LOCAL_PORT [2] 0
SOCK_REMOTE_PORT [2] 4000
SOCKET [2] is a TSAT-NMS TCP/IP Client
socket, and will connect to the Server socket
on the Master-HUB.
• Connect with Serial cable.
Configure COM-1 on both
Master- and Slave-HUB, and connect them together with a serial
cable.
MIB Parameter MIB Value Description
PORT_TYPE [1] 2 – SERVICE
PORT_USE_SOCKET [1] 0
PORT_USE_COM [1] 1
PORT [1] is SERVICE, and is using COM [1]
PORT_BIT_RATE [1] 115200
PORT_DATA_BITS [1] 8
PORT_STOP_BITS [1] 1
PORT_PARITY [1] 0
COM [1] is 115200,n,8,1.
Note: The Hub will use NET_RT_ADDRESS to distinguish between the other Hubs, so this MIB
parameter must be set different on all connected Hubs. It’s recommended to use the same
HUB-number as the NMS does (however, any value less than 256 will work ok).
Debugging
Some debug information is issued when you enable bit 8 (0x0100 –
DEBUG_MIL) in
UTL_DEBUG_MASK_B. Two other bits control debugging of the communication link between
Slave- and Master-HUB. That is bit 4 (0x0010 –
DEBUG_H2H_CTRL) and bit 5 (0x0020 –
DEBUG_H2H_DATA) in UTL_DEBUG_MASK_B.
Disable TX Gain Control
Tx Gain control is by default disabled when unit is configured as Slave-HUB. The following
MIBs are set to default values:
• GAIN_TX_OVERRIDE = 1 - Nearly no Tx Gain.
• GAIN_TX_REF = 1.0 - Disable AGC. Don’t ever read the Tx-Detector.
• GAIN_TX_END2END_TARGET = 0 - Disable “End-to-End Tx Gain” facility.
You may later change CURRENT (or FLASH) values, but these default values are
nevertheless applied the next time CCU is restarted.
