Configuring the Encompass 4H Reader
8-17
By default, the Encompass 4H Reader operates in predefined output mode where
sense output0 and sense output1 are asserted every time a unique valid tag is read.
Both sense output devices are asserted by issuing command #621 Predefined Output
Control. The devices are not asserted when tags are acquired in the transmit all or buf-
fer all ID mode or when the Encompass 4H Reader is operating in Wiegand mode.
The sense output pulse duration is variable (command #67N).

The host computer can disable the predefined sense output control by issuing com-
mand #6201 to turn sense output0 on or by issuing any of the following commands:

mand #6201 to turn sense output0 on or by issuing any of the following commands:
#6200
Turn Off Both Output Ports, #6201 Turn Off Output0, On Output1, #6202
Turn Off Output1, On Output0, or #6203 Turn On Both Output Ports. While under
host control, the sense outputs are not automatically asserted when a valid tag is read.
The host must issue command #621 Predefined Output Mode to return to the pre-
defined mode.

Serial Port Communications
The Encompass 4H Reader supports one communications port, which can be ordered
as either RS
as either RS

232/Wiegand or RS

munications specifications, the Encompass 4H Reader maintains the following three
sets of parameters that affect serial port communications:
sets of parameters that affect serial port communications:
•
Port configuration parameters (baud rate, data bits, stop bits, parity)
•
Communications protocols (basic, error correcting)
•
Flow control scheme (none, software, hardware)
The default serial port configuration for each of these three parameters is as follows:
•
9600 baud, 8 data bits, 1 stop bit, no parity
•
Basic communications protocol
•
Software flow control (XON/XOFF)
You can change these parameters in data mode and command mode operation by issu-
ing commands with the host computer. Use the following procedures to set serial port
communications parameters using the terminal emulation program.
