2 - 10 DS457-XX20004ZZWW Fixed Mount Imager Integration Guide
Serial Interface Cable Connection
When connecting via RS-232, identify the type of host system to determine the cable needed. If you are unsure
what host system you are using, contact the local Zebra representative.
TTL Level Compatible RS-232 Host Systems
If using a PC, laptop, or POS terminal, the host system most likely has an RS-232 port which is compatible with
TTL levels. In this case, use the standard 5V RS-232 cable.
Host Systems Which Require True RS-232 Levels
Some host devices are not compatible with TTL level signals and require true RS-232 levels, such as those in
electrically noisy environments and locations with long cable runs. In such installations the DS457 may require
a level-shifting cable, such as p/n 25-62186-03R, to interface to this host system.
Failure to use the appropriate cable can impact the imager’s ability to reliably communicate with the host under
some conditions.

Location and Positioning
The location and positioning guidelines do not consider unique application characteristics. Zebra recommends
that an opto-mechanical engineer perform an opto-mechanical analysis prior to integration.

NOTE Integrate the imager in an environment no more extreme than the product’s specification, where the
imager will not exceed its temperature range. For instance, do not mount the imager onto or next to a large
heat source. When placing the imager with another device, ensure there is proper convection or venting
for heat. Follow these suggestions to ensure product longevity, warranty, and overall satisfaction with the
imager.
