Shared Printer Switch Communication Wiring
Shared Printer Switch
A Shared Printer Switch (SPS) is used to allow two to four Series 1000/Fleetkey units to share
a single printer as a transaction logger. The RS-232 wiring configuration may be used
whenever the distance from each unit to the SPS is less than 100 feet. The RS-422 wiring
configuration must be used whenever distances are between 101 to 1500 feet, and requires the
use of a Gasboy Short Haul Modem (Gasboy Part Number C05618). Follow all wiring
requirements and installation notes listed in the beginning of this chapter. The SPS must be
connected to Port 1 of the FleetKey/Series 1000 because it is the only port that supports direct
printout or logger functions. The SPS is available as a 2 port kit Gasboy Part Number C09360
or a 4 port kit Gasboy Part Number C09361 which includes the appropriate SPS and proper
number of associated cables. The cables have an identifying tag at one end, which is also the
end that must be connected to the SPS. If the cable is reversed, communication will be
blocked. The SPS is used with the standard factory jumper selections. JP1 and JP3 are
jumpered, JP2 and JP4 are not jumpered. Connection and cabling diagrams are shown below
and on the following page.
