2.3.6 CAN1 / CAN2 Connector
The integrated network contains either two high-speed dual-wire CAN channels, or one single-wire
CAN channel and one high-speed dual-wire CAN channel. If you did not specify at the time of
purchase that the unit needs to have a single-wire channel, then it does not have one and has two
dual-wire CAN channels instead.
The high-speed dual-wire CAN channels use a Philips CAN transceiver P/N TJA1050 and an
Infineon TLE6250G transceiver. The single-wire CAN channel uses the Melexis single-wire CAN
transceiver P/N TH8056 and conforms to GM specification GMW 3089 revision 2.2.

WARNING!
Never connect more than one power source at a time to the S4 tool.
Inputs handle 0-32VDC, and include hysteresis / transient protection. Any of the 3 inputs can be
configured via internal jumpers to cause a power-up event on either rising or falling logical edge.
Inputs can be treated both as immediate values (the driver returns the current state) or edge
detectors (the driver returns a latched edge and can clear such events on demand).
No pull-up to the appropriate passive state is required externally.
Outputs are 1A sinks (MOSFET switch to ground).

supports USB Flash Drives, GPS and the supplied Buffalo Wireless Adapter (P/N WLI-UC-
GNM).
2.3.9 Module Connector (Optional)
A single module slot is provided with the S4 hardware. Each installed module will have
connector information. Any expansion module can provide power to the S4 tool. Please make
certain of the pin assignments for the individual module before applying voltage to the pins
marked VBAT (positive or negative).
WARNING!
Never connect more than one power source at a time to the S4 tool.
2.4 Internal Hardware
There are jumpers and headers on the board referenced in other sections of this manual.
2.4.1 USB
There are two headers for internal USB ports located next to the external USB ports. Refer to
the diagram in section 2.4.2 for the location.
2.4.2 Input Jumpers
As viewed from the top of the board with the front of the unit down, the jumpers are located in
the top right quarter of the board. These jumpers correspond to the three inputs on the
INPUT/OUTPUT connector. JP100, JP101, and JP102 correspond with input channels 1, 2,
and 3 respectively.
Placing a jumper over the two pins located toward the front access panel selects falling-edge
power-on for that channel.
Placing a jumper over the two pins located away from the front access panel selects rising-edge
power-on for that channel.
Removing the jumper will prevent a power-up event from occurring for that channel.

17
GRYPHON®
- S4 MANUAL
