WI-GTWY-9-xxx Wireless Gateway V1.18
136
Serial expansion modules can be connected to the RS485 port of all WI-GTWY-9 units except
for the WI-GTWY-9-MD1 unit.
If Serial Expansion modules are required
to connect to an MD1 then it it can only
be done under the following
circumstances.
•
If the
WI-GTWY
is configured
as a “Repeater-only” under
the Protocol selection .
•
IF the Serial expansion
module is setup as a Modbus
Slave and the the Gateway
module is a MD1 Master.
Up to 10 x WI-I/O-EX-1-S modules can
be connected to each WI-GTWY-9.
To enable the WI-GTWY-9 serial port for Serial expansion, select the “Enable Serial Expansion”
box as shown above.
Note that enabling Serial expansion also disables on-line diagnostics via the serial port.
Mappings are configured as per normal radio modules however the serial module is attached to
its corresponding radio. Select ‘Serial Units’ under the radio module and configure as normal
(see below).
Notes: Each WI-I/O-EX-1-S module has an address between 96 and 127 (modules can use up to
3 addresses).
The WI-GTWY-9 acts as a repeater for any mapping from the WI-I/O-EX-1-S, also any
mappings from other remote modules to the WI-I/O-EX-1-S will need to have the WI-GTWY-9
configured as a repeater.
The WI-GTWY-9 I/O registers can also be mapped to/from the 115S I/O.
