| User data rates |
Up to 19200 baud half or full duplex; 38400 baud half duplex in DSSS mode
Up to 9600 baud half or full duplex in FHSS mode
Baud-rate can be selected using a PC connected to the modem serial port. Any
communications software package (e.g. Procomm) is suitable for this task. |

Multipoint-to-multipoint in DSSS mode. |
| Repeaters |
Modem can be configured as repeater to extend range and coverage in DSSS mode. |
| Packet structure |
Data is grouped into packets for radio transmission. |
| Addressing |
255 unique addresses, 1 broadcast address, multicasting possible. |
| Security |
Unique password to prevent eavesdropping and unauthorized transmission in DSSS mode. |
| Error Control |
ARQ error control using CRC. |
| Buffering |
509 byte internal buffer; 1018 bytes buffer configure as repeater in DSSS mode. |
