Chapter 5: Programming 5-51
Terminator Byte
There are two RS-232 Terminator Bytes available–the second Terminator Byte being a direct
entry only. Therefore after programming the First Terminator Byte Hex 2, Hex 3 and Hex C
must be scanned to be able to program the Second Terminator Byte.
ASCII Code
The ASCII Code parameter for RS-232 Terminator Byte and Prefix Byte has the same
function. Refer to the “RS-232 Prefix Byte” section of this chapter for more information.

Your Program
The RS-232 Communications Options parameters control the delay between messages, and the
format in which the scanner and host terminal exchange tag data messages. The firmware is
programmed to accept one parameter at a time and then leave this programming mode.
Therefore, each of the parameters must be programmed separately. Refer to the “Parameter
Defaults” section earlier in this chapter for the factory defined default value of each
programming parameter.
Message Delay
The Message Delay option sets the minimum time the firmware waits before sending the next
message. This permits lowering CTS by the host terminal to inhibit data from the scanner. This
option was not available on previous scanners.
Messages can be delayed as follows:
Hex 0 for no delay
Hex 1 for a 10 ms delay
Hex 2 for a 50 ms delay
