Serial Ports
Three EIA-232 serial communications ports are available:
•
Serial Port 2 (side panel)
•
Serial Port 3 (side panel)
•
Serial Port F (front panel)
An EIA-485 serial communications port is available as an ordering
option:
•
Serial Port 1 (side panel)
Serial Port Default Settings
The default settings for all serial ports are:
Baud Rate = 2400
Data Bits = 8
Parity =
N
Stop Bits = 1
The serial port default settings can be changed from the front-panel
interface or from the serial communications port itself. After connecting
the appropriate communications cable and setting the terminal emulator,
press the ENTER key, and the control will respond with a “=” prompt,
which indicates Level 0 access is established – see Table 4.

Make Only One IRIG-B
Connection:
If making an IRIG-B connection,
connect demodulated IRIG-B time
code to either the serial Port 2 or
serial Port 1 connector (see the
following
EIA-485 Pinout
Functions for Port 1 ), but not
both.
