RS232:
No configuration of the Rx 1+1 Interface Module is required for proper RS232 operation.
Connect a suitable cable to connector J1. The RS232 port uses ASCII protocol and a
fixed baud rate of 9600 for communication. On the host computer set the serial port
settings to the following: Baud rate to 9600, data bits to 8, parity to none, stop bits to 1,
and flow control to none. The Rx 1+1 Interface Module can be accessed using a
terminal program on the host computer such as HyperTerminal. Hit enter several times
and you should see the “RX1+1>” prompt. Type CPE=1234 and the RX1+1> prompt
should return. The Rx 1+1 Interface Module is now ready to accept commands.
Following are two examples, which use the default settings. If you need to reconfigure
these settings, this describes the sequence of events:
To configure TCP/IP do the following:
CIA=192.168.1.254 // IP Address
CIG=192.168.1.1 // IP Gateway
CIM=24 // Subnet Mask
CIP=23 // Telnet Port
To configure RS485 do the following:
C4A=1 // RS485 Address
C4D=20 // RS485 Delay
C4R=9600 // RS485 Baud rate
RS485:
Communicating with the Rx 1+1 Interface Module across RS485 uses ASCII protocol.
Communication through a terminal program such as HyperTerminal requires an
onboard RS485 card in the host computer. In HyperTerminal type the password
command: <0001/CPE=1234 followed by the enter key. Once the < prompt comes back
the Rx 1+1 Interface Module is ready to accept commands. In the above example
<0001/ is the address of the Rx 1+1 Interface Module followed by the desired
command.
If an external box is used to convert RS232 to RS485, then a terminal program will not
function. These boxes are designed to work with the RTS/CTS lines manually which a
terminal program cannot handle. In these cases, a network management program is
required to handle this handshaking requirement.
HANDHELD TERMINAL (HHT):
No Rx 1+1 Interface Module configuration is required to use the HHT. To activate the
HHT, connect the supplied cable to the IBUC connector labeled J1 and plug the RJ11
connector into the HHT. Once a flashing cursor is seen in the upper left part of the
screen, press the decimal key on the HHT 4 times to activate the HHT. The login screen
