4–10 Configuring the SCANTEAM 3700
Set Trigger Mode Command Kg
COMMAND
<Kg mode_global, mode_port_1, mode_port_2, #>
Parameter ASCII Option
Mode 0 Continuous Read
Mode 1 Continuous Read, Send Once, Clear on Timeout
Mode 2 External Trigger, Read While Active
Mode 3 External Trigger, Read Once
Mode 4 Serial Trigger
Mode 5 Serial Trigger or External Trigger,
Read Once *
Sending the configuration command Kg sets the trigger mode. The command string is
interpreted left to right. For example, if you send the following command: <Kg 4, 0>,
both ports will be set to mode 4, then port 1 changes back to mode 0. Likewise, if you
send the following command: <Kg , 0, 4>, port 1 is set to mode 0 and port 2 is set to
mode 4. Both commands have the same end result; port 1 will be in continuous read
mode and port 2 will be in serial trigger mode. The default setting is Mode_global 5,
selecting a serial trigger or an external trigger, one read.
Tip 1: Careful consideration must be taken when configuring multiple ports to a
continuous trigger mode. The 3700 decodes from only one port at a time. With
multiple ports triggered, the 3700 will select each in turn and attempt to read. If
no bar code label is present at the selected port, the 3700 will wait for read
timeout to expire before stepping to the next port. If read timeout is set to a value
near or greater than the time it takes a bar code label to pass by a scanner, then
the label will often be missed.
Set Read Timeout Command Kh
COMMAND
<Kh mode_global, time_global, mode_port_1, time_port_1,
mode_port_2, time_port_2, #, #>
Parameter
ASCII Option
Mode 0 Timeout Ends a Read Attempt * (150)
Time one to five ASCII digits,
range of 10 to 65000
Sending the configuration command Kh sets the read timeout. One to five ASCII digits
in the range of 10 to 65,000 determine the number of 10ms increments of time that the
3700 will, once triggered, wait while attempting to read from a port. For example, if you
wanted to set port 1 to timeout ends a read attempt after 100ms; you would send the
following command: <Kh , , 0, 10>. Port 2 is not changed. The default setting is
Mode_global 0 and Time_global 150 (150 x 10 msec = 1.5 seconds).
