Model 5052RD-K ALERT2 Receiver/Decoder
Page 12
A102688
ALERT2 decoder output is through the back panel ETHERNET RJ45 network, SERIAL
DB9 female ALERT2, and SERIAL DB9 male CONSOLE serial connectors. ALERT2
Demodulator & Decoder ASCII and Binary Asynchronous Serial Interface format outputs
are provided on the network connection. Only the ALERT2 Demodulator & Decoder ASCII
Asynchronous Serial Interface format output is provided on the serial connections.
The ALERT2 decoder output serial connection is at 19200 baud, no parity, 8 data bits, no
stop bits, no flow control.
The ALERT2 decoder supports multiple server and client network connections. See
Section 4 for network client connection programming.
The ALERT2 decoder in server mode listens for TCP/IP network connections from up to
25 base station computers on port 4200 for ALERT2 Decoder ASCII format output and
port 4201 for ALERT2 Decoder Binary format output. There is no attempted reconnect for
connections lost in server mode.
The ALERT2 decoder in client mode will make TCP/IP network connections with remote
base station computer IP addresses and ports. The ALERT2 Receiver/Decoder will
attempt a reconnect every 30 seconds.
3.5.3 ALERT1 Decoder Output
ALERT1 decoder output is through the back panel ETHERNET RJ45 ALERT1 network
and SERIAL DB9 female ALERT1 serial connector when the Model 5052RD-OP1
ALERT1 Receiver/Decoder Option is installed. ALERT1 ASCII and Binary format outputs
are provided on the network connection and serial connection.
The ALERT1 decoder output serial connection is at 300 baud, no parity, 8 data bits, no
stop bits, no flow control.
The ALERT1 decoder supports multiple server or a single client connections. See Section
4 for network connection programming.
The ALERT1 decoder in server mode listens for TCP/IP network connections from
multiple base station computers on port 2101.
The ALERT1 decoder in client mode will make a single TCP/IP network connection with
remote base station computer IP address and port.
3.5.4 ALERT2 Transmit Input
ALERT2 encoder data input is through the back panel ETHERNET RJ45 ALERT2
network connector when the Model 5052RD-OP2 ALERT2 Transmit Option is installed.
The ALERT2 IND Encoder & Modulator Asynchronous Binary Serial Interface format is
supported.
