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 4 Reader supports one communications port, which can be ordered as
either RS
–232/Wiegand or RS–422/Wiegand. For the RS–232 and RS–422 communi-
cations specifications, the Encompass 4 Reader maintains the following three 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.
Port Configuration Parameters
Use this procedure to set port configuration parameters using the terminal emulation
program. Consult sections
“100N Select Baud Rate" through “102N Select Parity” on
page 7-7.
To set baud rate
1. Ensure that the host computer is in command mode.
2. Enter command #100N and press ENTER.
To set stop bits
1. Ensure that the host computer is in command mode.
2. Enter command #101N and press ENTER.
To set parity
1. Ensure that the host computer is in command mode.
2. Enter command #102N and press ENTER.
