- Long-range data communication via frequency shift key (FSK) simplex, half and full-duplex modem
- Ideal for non-switched private wire (spare pair) or leased telephone lines or any dedicated wire pair
- Two or four-wire operation
The LLM1100 is microprocessor-based, with a range of 20 miles (32 km) on any ordinary wire pair or unlimited on-loaded telephone company voice-grade (VG-6) leased lines or equivalent depending upon wire size and line quality.
Product Description
The Data-Linc Group LLM1100 is a Bell 202, 1200 baud modem. It can be easily configured for simplex (bit mode), half-duplex and full-duplex operations. The wired modem is designed to be used on private, leased non-switched telephone lines or any dedicated two-conductor wire (twisted or untwisted, shielded, or unshielded).
The LLM1100 is microprocessor-based— when the carrier shuts off, data bit errors are eliminated. This reduces retransmissions for trouble-free PLC communications. It also incorporates a unique data sense carrier control feature that eliminates the need for RTS/CTS control on multi-point Remotes.
The modem easily interfaces with most PLCs, RTUs, and PCs and also supports the RS232 interface.
