4、IO Attemper Function
HXJZ-873 have two communicate protocol: full transparence protocol and ID protocol.
(Remark: full transparence protocol is default protocol, if you need HXJZ-873 with ID protocol,
please tell us when you book )
1) Full transparence protocol
In this mode, whatever you use, any data frame, HXJZ-873 can send it to another side as like as two
peas, it cannot change data format and data bits. HXJZ-873 with this transmit mode be used for Reading
meter, RTU and PLC with Address itself and so on.
2) ID protocol
When your terminal without Address or ID, you can use HXJZ-873 with ID protocol , in
this way you can differentiate the data from you terminal. The Main station you must use HXJZ-873 with
full
transparence
protocol,
the appurtenant station you must use HXJZ-873 with ID protocol. The HXJZ-873 of the appurtenant station
must set
ID according our RF module software, you can resolve the data from user terminal transmit according to ID
Protocol.
Remark: when you use HXJZ-873 with ID protocol, we provide
《communication protocol of HXJZ-
873》
and
programme manual.
3) IO attemper function
You can use one HXJZ-873 with full transparence protocol for the Main station, some HXJZ-873 with ID
protocol
for the appurtenant stations, each HXJZ-873 of the appurtenant station must set one unrepeatable
ID. You can attemper the appurtenant station IO according to communication protocol of HXJZ-873.
Remark:
when
you
use
IO
attemper
function,
we
provide
《communication
protocol
of
HXJZ-873》
and
programme manual.
HXJZ-873 parameters setting
HXJZ-873 have one interface of
TTL、RS232、RS485, You must specify the interface when you buy.
HXJZ-873
main parameters: COM baud rate and verify，RF baud rate, Channel and frequency。You can change these
parameters by our RF Module soft. When RF baud rate is faster than COM baud rate，One frame Can transmit
limitless data. When RF baud rate is not faster than COM baud rate
，
One frame Can transmit 255 bytes most.
You can set the rate according your need.
The general Power supply is 5V DC.
Two HXJZ-873 communicate must have condition as follow:
1.Their channels (i.e. frequency) are the same.
2.Their RF rates are the same.
3.RF Module Com baud rate and verify is agree with its equipment or PC that it connects with.
Parameters default value:
Channel：
1
Interface speed rate：9600BPS
Interface verify：none
Speed rate in air：9600BPS
