RadioLinx RLX-FHS modem
Problem Solution Overview
We performed testing between the subject device and our 3100-MCM and 3150-MCM product.
Solution Brief
Our testing generated the following results:
- We were able to successfully communicate through the modems. (see below for configuration parameters used during the testing)
The purpose of our testing is to assure a level of compatibility in the communications between the two products. Through this testing, we attempt to identify problem areas that may arise when implementing the interface in the field.
Configuration:
The product testing was performed with the following settings used:
Port 1:
- Baud: 9600
- Parity: None
- Stop: 1
- Mode: RTU Master Mode
- Physical Connection: RS-485 & RS-232
Port 2:
- Baud: 9600
- Parity: None
- Stop: 1
- Mode: RTU Slave Mode
- Physical Connection: RS-485 & RS-232

This configuration in combination with the example ladder logic referenced below generates the following memory map:
N10:0 to N10:129- Slave Data
N10:130 to N10:149- Slave Error Table (Contains revision level information also)
N10:150 to N10:199- Master Error Table (Contains status of commands for diagnostics)

Additional Comments and Observations:
- Model tested: RLX-FHS Radio Modem
- RTS / CTS must be jumpered.
Radio Setup Considerations: (Using RadioLinx ControlScape FH Software)
1) Configure the Network to use a Point-Multipoint Modbus Network Type.
2) Baud rate for each modem must mach the 31xx-MCM settings with no handshaking.
3) When downloading Radio configuration from PC, ensure that no data is transferring
