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).
