External or internal power supply of module Expansion port RS485/RS422 can be
made by wiring jumpers J2 and J3 on this module. If external power supply of the module is
required, jumpers J2 and J3 must be connected to pins 2 - 3. Internal power supply is made by
connecting pins 1 - 2 with jumpers J2 and J3.
Interface behavior of module Expansion port RS485/RS422 can be made by wiring
jumpers J4, J5 and J6 on this module. If RS485 is required, jumpers J4 and J5 must be
connected and jumper J6 disconnected. If RS422 is required, jumpers J4 and J5 must be
disconnected and jumper J6 connected.
Jumper placement can be seen in the picture below (module Expansion port
RS485/RS422 from TOP layer). We recommend that internal power supply is only chosen
in the event that it is not possible to ensure external power supply. If internal power supply is
chosen, converter RS485/RS422 is not galvanic separated.

- Module received cell 6e91 on channel 107 with level 77db
- If many cell with close signal levels 3 db be in danger of reselection switching between cells that caused bad time response or communication interruption in this case is needed to extend difference between signals
- Good quality gprs requirements
- Good placement of antenna is required for good function important factors are gsm cell signal strength and signal quality signal strength could me measured by function gprs receive signal strength measuring in program radwin second part is quality of signal there is no exact measurement good point of view is from data transfer statistic if number of lost packet is low signal quality is good
- Example station received these signals
- Change type from unidirectional to directional e g yagi direction or place of antenna after changing you must do measurements again
- Cgu 04i description
- Antenna installation for modems
- Adjacent cell signal below 12db to serving cell otherwise risk of interference
- What does it means
- Way to fix
- There is possible to reselection between channels 76 106 107 and 33 its level is so close
- There is possible to interference from channel 106 with level 79dbm
- The agnes system works with the aid of the gsm network the agnes stations contain gsm gprs modules which are on the radio channel connected to a certain gsm cell its signal can be evaluated with the aid of this function the function is used first of all when installing the station and checking its function from the obtained information the following can be read on which channel the station operates what is its signal strength what neighbour channels are available and what their signal is strength these data are often indispensable for the correct installation of the antenna
- Serving cell signal better than 90dbm
- Quality of the gprs signal
- Serving cell
- Run radwin function gprs receive signal strength measuring answer is information about serving and remaining cells output is from at commands at moni and at monp from gprs module
