M48A : Modem application board

M48A - Modem application board

The apps board presents the M48 modem, combined with a radio module (either USX or BiM/NiM family) and suitable interface circuits, power supplies and connectors. Optionally, the board can be housed in an EAS80 (or EAS120) extruded aluminium housing. In the simplest case, a pair of these units (with suitable aerials and power supplies connected, of course) can be connected directly to the serial ports of a pair of industrial PCs and the resulting wireless data link used without any further installation or programming.

Features

• Maximum usage of the range capability of an RF module
• 5kbps pulse duration coded protocol
• Synchronisation codes and checksum to reduce false triggering on noise
• Programmable transmit address and four receive addresses
• Programmable timing parameters (preamble length, etc)
• Programmable auxiliary serial output (to program radio modules)
• Programmable serial modem baud rate (1200 - 76800 bps, half-duplex)
• Addressable point-to-point and point to multi point
• Packet acknowledge/resend (ACK) mode
• Store and forward repeater function
