Can Bus; Input/Output - Iridium Edge Pro Development Kit Manual

4.4 RS-485
The RS-485 Interface is shown in Figure 4-5. The RS-485 interface provides a direct connection
to the Iridium Edge Pro's device's RS-485 signals. The interface, labelled as RS-485, reference
designator J12, is a 4-position screwless, spring loaded terminal block that supports 20-26 AWG
wire.

CAN Bus

The CAN Bus Interface provides a direct connection to the Iridium Edge Pro's device's CAN Bus
signals. The interface, labelled as CAN BUS, reference designator J12 on the TIC) is a 4-position
screwless, spring loaded terminal block, as shown in Figure 4-6. The terminal block can be used
with 20-26 AWG wire and provides a direct connection to the Iridium Edge Pro CAN Bus signals.

Input/Output

The Iridium Edge Pro has two Digital or Analog inputs (IN_1 and IN_2) and two Digital
Input/Outputs (IO_3 and IO_4). Refer to the Iridium Edge Pro Hardware Developer Guide [
Reference 1] for complete details on the I/O interface as well as the IO_RET1 and IO_RET2
ground return that can be optionally used with the I/Os.
The TIC supports both Remote I/O testing and Local I/O testing. With Remote testing, the Iridium
Edge Pro I/Os are connected directly to external devices, remote from the TIC. With Local the TIC
provides test capabilities to both monitor digital I/Os or set digital and analogue inputs. The switch
settings as defined in Table 4-1: Local/Remote Selection Switchescan be set to LOCAL or
REMOTE.
Controlled for export under the EAR. See front cover for use and disclosure statement.
