Communications Commands

Note: Changes in Communications parameters or assigning an address to the
decoder can cause loss of communications with the configuration terminal when
you exit the menu program (whether or not changes are saved for power-on).
Protocol
If selecting one of the options from 0 to 4 (Point-to-Point, Point-to-Point with
RTS/CTS, Point-to-Point with XON/XOFF, Point-to-Point with RTS/CTS and
XON/XOFF, or Polling Mode D), use this format:
Format: <Kfprotocol>
protocol:
0 = Point-to-Point
1 = Point-to-Point with RTS/CTS
2 = Point-to-Point with XON/XOFF
3 = Point-to-Point with RTS/CTS & XON/XOFF
Example: To change the Protocol to Polling Mode D, enter <Kf4>.
If selecting Multidrop (5), you must define an address and add it to the for-
mat (data B).
Format: <Kfprotocol,address>
protocol:
5 = Multidrop (requires address)
Example: To change the Protocol to Multidrop with an address of 33, enter
<Kf5,33>.
If selecting User Defined (6) or User Defined Multidrop (7), you must com-
plete the format by either choosing new parameters or concatenating
unchanged data fields (separate by commas).
Tip: For User Defined, you first select Point-to-Point <Kf0> and then User
Defined <Kf6...>. For user Defined Multidrop, you first select Multidrop <Kf5>,
then User Defined Multidrop <Kf7...>.
Format: <Kfprotocol,RES,address,
REQ,EOT,STX,ETX,ACK,NAK>
Protocol:
6 = User Defined
Example: To select an unpolled ACK/NAK User Defined protocol with LRC
disabled, enter <Kf0><Kf6,,,,,,,^F,^U><Kc0>.
