RS-232 ONLY Interface
Introduction
Use the programming barcodes in this chapter if modifications to the standard RS-232
interface settings are necessary to meet your system’s requirements. Additional settings
which apply to both the RS-232 and USB interfaces are available in Chapter 6, RS-232/
USB-Com Interfaces.
RS-232 Standard Factory Settings
Reference Appendix B, Standard Defaults for a listing of standard factory settings.
Baud Rate
Baud rate is the number of bits of data transmitted per second. Set the reader's baud rate
to match the baud rate setting of the host device. With an improper baud rate setting,
data may not reach the host correctly.
ENTER/EXIT PROGRAMMING MODE
Baud Rate = 1200
Baud Rate = 2400
Baud Rate = 4800

Data Bits

Data Bits
This parameter allows the reader to interface with devices requiring a 7-bit or 8-bit
ASCII protocol for sending and receiving data.
ENTER/EXIT PROGRAMMING MODE

8 Data Bits

Stop Bits
The stop bit(s) at the end of each transmitted character marks the end of transmission of
one character and prepares the receiving device for the next character in the serial data
stream. The number of stop bits selected (one or two) depends on the number the receiv-
ing terminal is programmed to accommodate. Set the number of stop bits to match host
device requirements.
ENTER/EXIT PROGRAMMING MODE
1 Stop Bit
2 Stop Bits
DEFAULT

Parity
Product Reference Guide 45
Parity
This feature specifies parity required for sending and receiving data. A parity check bit is
the most significant bit of each ASCII coded character. Select the parity type according
to host device requirements.
• Select None when no parity bit is required.
• Select Odd parity and the parity bit value is set to 0 or 1, based on data, to ensure that an
odd number of 1 bits are contained in the coded character.
• Select Even parity and the parity bit value is set to 0 or 1, based on data, to ensure that an
even number of 1 bits are contained in the coded character.
ENTER/EXIT PROGRAMMING MODE
Parity = None
Parity = Even
Parity = Odd

Handshaking Control
The data interface consists of an RS-232 port designed to operate either with or without
the hardware handshaking lines, Request to Send (RTS), and Clear to Send (CTS). Hand-
shaking Control includes the following options:
• RTS — RTS is asserted during transmissions. CTS is ignored.
• RTS/CTS — RTS is asserted during transmissions. CTS gates transmissions.
• RTS/XON/XOFF — RTS is asserted during transmissions. CTS is ignored. XON and
XOFF gate transmissions.
• RTS On/CTS — RTS is always asserted. CTS gates transmissions.
• RTS/CTS Scan Control — RTS is asserted during transmissions. CTS gates transmis-
sions and controls enable and disable state of scanner.
ENTER/EXIT PROGRAMMING MODE
Handshaking Control = RTS
Handshaking Control = RTS/CTS
Handshaking Control = RTS/XON/XOFF
Handshaking Control = RTS On/CTS
Handshaking Control = RTS/CTS Scan Control

Intercharacter Delay
This parameter specifies the intercharacter delay between the end of one character and the
beginning of the next. The delay can be set within a range of zero (0) to 990 milliseconds
in 10ms increments. A setting of zero specifies no delay.
To set the delay:
1. Determine the desired setting in milliseconds.
2. Divide the desired setting by 10 (setting is in 10ms increments). Pad the result with lead-
ing zeroes to yield two digits. For example: 0 = 00, 5 = 05, 20 = 20, etc.
3. Scan the ENTER/EXIT PROGRAMMING MODE barcode to enter Programming
Mode.
4. Scan the barcode: SELECT INTERCHARACTER DELAY SETTING.
5. Scan the appropriate two digits from the keypad in Appendix E, Keypad, that represent
the duration which was determined in the steps above. You will hear a two-beep indica-
tion after the last character.
6. Scan the ENTER/EXIT PROGRAMMING MODE barcode to exit Programming
Mode.
This completes the procedure. See Table 7 for some examples of how to set this feature.
Table 7. Intercharacter Delay Setting Examples
NOTE
If you make a mistake before the last character, scan the CANCEL barcode to
abort and not save the entry string. You can then start again at the beginning.

zeroes to yield two-digits) 05 15 60 85
