Description
Value
:SERial
Controls Serial Interface settings
:BAUD
9600
Sets serial baud rate. Values = 300 to
115,200 in all standard rates. Parser uses
closest divider for non-standard rates.
:PARity
NONE
Sets serial parity. Values = EVEN, ODD or
NONE.
:BITS
8
Sets number of data bits per character. Val-
ues= 7 | 8.
:SBITs
1
Sets number of stop bits between characters.
Value = 1 | 2.
RS485
1
Enables full duplex operation on the RS-
485 port. Must be set to 1. Values are 0 and
1.
:NETwork
OFF
Selects RS-485 communication protocol.
OFF selects no protocol and uses standard
ASCII character messages for point-to-point
operation. ADDRess enables ICS's net-
work protocol. When network is enabled,
every serial message has to be preceded by
a two character, <STX><Addr> sequence
and is terminated with a linefeed character.
PACKet enables ICS's packet protocol.
When packet protocl is enabled, the 2363
only recognizes packets sent to it at its
network address and with the corect check-
sum. The 2363 responds to each valid
packet with an ACK, NAK or response
packet. Values are OFF, ADDRess and
PACKet. Use an :UPdate command or
power cycle the unit to switch to the new
protocol setting.
Note: Earlier units did not have the packet
protocol and their value choices were OFF
and ON where ON enabled the network
address mode.
