CONFIGURATION
The ESTeem Horizon has a proprietary RS-232C
interface in a RJ-45 connector on the front panel. To
interface the Horizon to the serial port on the computer,
you need ESTeem cable AA0621 that combines a
standard Ethernet patch cable to a 9-pin Female adapter.
The serial port on the ESTeem Horizon can be used to
access the configuration menu in the ESTeem for system
and network configuration. The ESTeem
communications port operates at 38,400 bps, No Parity, 8
Data Bits and 1 Stop Bit (38,400,N,8,1). Configure your
terminal program to match these settings.
