General
The TSX SCY 21601 module manages two independent communication channels which each
have their own functions:


Channel 0 deals with Uni-Telway, Modbus and Character Mode protocols on an isolated
physical link, and with standardized RS 485 half duplex with a speed limited to 19200 bits per
second.
Channel 1 receives one of the following PCMCIA communication cards:
 Cell network: TSX FPP 20 Fipway card.
 Field Bus: TSX SCP 111 (RS232), TSX SCP 112 (current loop), TSX SCP 114 (RS 422/RS
485) Uni-Telway, Jbus/Modbus and Character mode cards.
The choice of PCMCIA card and protocol is made when the TSX SCY 21601 module’s
communication channels are configured using Unity Proware.
