The GDP Model 2360-M20 Serial TTL I/O AMC 2 channel module is a pluggable and hot-swappable AMC (Advanced Mezzanine Card) module. This module provides the serial and telemetry interfaces to the Model 2360 link modules such as Ethernet and ATM. Channels may be individually controlled as inputs or outputs. Input channels convert the serial data into IP packets for transport across the backplane to link modules. Output channels receive IP packets from the backplane and convert into serial clock and data.
