Internal Communication Channels:
• FSK modulated signal to control the Beamer FLEXBEAMER® or BAU Beamer
units.
• Parallel TTL Level lines to control the ABTs of the RAC.
External Communication Channels:
• RS485 through an external connector to BSM operated Local PC
• RS232 through the Wireless Modem to the CDMA network and remote BSM
operated PC.
