Metrologic Instruments MS9500 manual Programming Modes, How does Serial Programming work?

Programming Modes

The MS9500 Voyager has 3 modes of programming.

Bar Codes: Voyager can be configured by scanning the bar codes located in the METROSELECT® Configuration Guide (MLPN 2407). Please refer to this guide for instructions. This manual can be downloaded for FREE from Metrologic’s website (www.metrologic.com).

MetroSet™: This user-friendly Windows-based configuration program allows you to simply ‘point-and-click’ at the desired scanner options. This program can be downloaded for FREE from Metrologic’ website (www.metrologic.com), or set-up disks can be ordered by calling 1-800- ID-METRO.

Serial Programming: This mode of programming is ideal for OEM applications. This mode gives the end-user the ability to send a series of commands using the serial port of the host system. The commands are equivalent to the numerical values of the bar codes located in the MetroSelect Configuration Guide (MLPN 2407).

How does Serial Programming work?

1.Each command sent to the scanner is the ASCII representation of each numeral in the configuration bar code. The entire numeric string is framed with an ASCII [stx] and an ASCII [etx].

EXAMPLE #1: Command for Disabling Codabar Command = [stx]100104[etx]

String Sent to Scanner = 02h 31h 30h 30h 31h 30h 34h 03h (All values are hexadecimal).

2.If the command sent to the scanner is valid, the scanner will respond with an [ack].

3.If the command sent to the scanner in invalid, the scanner will respond with a [nak].

NOTE: If this occurs, the end-user must start over at the very beginning of the configuration sequence. Simply re-tranmsitting the invalid command will not work, you must start over.
