The format for the COM Port configuration information is as follows:
5-digit LED Group ID: 33333
LED-1: COM Port number
LED-3: Data Bit: 5 , 6 , 7 or 8
LED-4: Parity Bit, n = no parity, E = even parity, O = odd parity
M = mark parity, S = space parity
LED-5: Stop Bit: 1 or 2
The format for the connected clients and debugging information is as follows:
5-digit LED Group ID: 44444
LED-1 will display 1, 2, 3, 4, 5 and the module name in sequence.
When LED-1 is 1, LED-2/3 indicates the number of available free sockets (default is
26 for PDS), and LED-4/5 shows the number of sockets being used by clients (default
is 0), e.g. 12600
When LED-1 is 2, LED-2~5 indicates how many times the PDS has been reset, e.g.
20002 (The PDS-700 has been reset 2 times)
When LED-1 is 3, the display indicates how many Ethernet packets are currently being
received by the PDS.
When LED-1 is 4, the display indicates that the status of the internal Flag used to
allow Ethernet packets to be sent is 0 or 1.
When LED-1 is 5, the display indicates the number of times the Ethernet chip has been

Module Name: dS.7xx
When the PDS is first powered-up or if it has just been reset, the reset state = 1. If any
client connects to the PDS, the reset state will be changed to 0. In addition, the number of
free sockets will be decreased and the number of used sockets will be increased. If the
number of free sockets is reduced to 0, then no additional clients will be able to link to the
PDS. The default number of free-sockets for the PDS is 26. Therefore, the server
(VxComm firmware or Xserver firmware) allows 26 connections to be linked to a single
PDS. Each client program occupies at least 2 connections for a single serial port, one
connection for data and another for commands.
