ZigBee Communications Gateway
e. RS232/RS485 Tunnelling
This is only available on GW357 gateway models which have the RS232\RS485 option (see
the order codes table.) A “Module 2” check box will also be present if your GW357 has a
second ETRX3 ZigBee module fitted.
This option creates a direct connection between the RS232 or RS485 port on the gateway
and the ETRX3 ZigBee module.
The GW357 doesn’t support addressing in multidrop networks. Any data received on the
RS485 port will be automatically forwarded to the ETRX3 ZigBee module.
f. RS232/RS485 Port Configuration
This option is only available on GW357 gateway models which have the RS232\RS485 option
(see the order codes table.)
Here the user can select the RS232 and RS485 port settings. Note: it is recommended
(although not a requirement) that the RS232/RS485 port on the gateway and the ETRX3
ZigBee module have the same baud rate. The gateway has a limited capacity to buffer
messages; ensuring the baud rates are the same removes the potential for a buffer overflow
in the RX or TX paths.
g. Discovery
This option is enables the Gateway to send discovery broadcasts by UDP on port 14099
once every minute. This option is enabled by default.
h. Button Command
This is a command string that will be sent to the 1
st
ETRX3 ZigBee module each time the
Button-2 (B2) is pressed.
