Copy the configuration to the RC250 using the
Set RX
Button.
* To gain access to the transmitter programming socket the bottom cover
must be removed (2 x pozi-drive screws). Carefully remove the battery pack
but do not disconnect it. The programming socket is a 3mm stereo jack
socket that will now be accessible.

Columns in the RX Configuration panel table:
Chan
RC250 channel (maximum 160 channels)
Tx Serial
Tx serial number
Tx Chan
TX channel (alpha character A to H)
Tx Range
TX channel range e.g. Humidity SHT if the B channel of a GD10
(see Page 9 for an example of the Edit Rx Channel pane)
Value
Tx value of the last valid data received expressed in units
allocated to the range. These can be default or configured as
engineering units.
Batt
Tx battery condition expressed in %
Age
Time, in seconds, since the last valid reading received. Age will
not be normally greater than 2 times the transmission interval. If
it is, there may be permanent or temporary loss of
communications and should be investigated.
Nbr TX
Number of successful transmissions received, indicates the
reliability of performance and is for comparison purposes only.
11.3.1
No Data Interval
Within the Edit RX Channel window is the feature No data Interval.
The RC250 expects new channel information from the transmitter on a
frequent basis to refresh the last valid value held in a buffer. If data is not
received within a configurable period, e.g. due to transmitter failure, the value
is reported as No Data. This in turn can be processed as appropriate to the
application by the connected software.
The No data Interval will default to the TX interval x 6 and can be set (as
hh.mm.ss) for special applications on a per channel basis.
11.4
ModBus configuration
The ModBus Setup menu (Tools - Modbus setup) allows the user to configure
the ModBus device address and the holding register addresses for the various
parameters. Node Address should be set to the required slave device ident.
The following six boxes are for specifying the start address of holding registers
for reporting the transmitter information. The value in each of these boxes
must be greater than that in the previous box. The difference must be greater
than the number of channels configured in the RC250.
