Connectors and Operating
Elements
The following connections can be used depending on the version:
2 x 9-pin D-Sub connectors (IPEH-002210/11)
10-pin screw terminal block (IPEH-002210-P)
I/O-Pin: digital input on CAN channel 2 (IPEH-002210)
I/O-Pin: digital input on CAN channel 1 (IPEH-002211)
RS-232 interface for serial data transmission (IPEH-002210-P)
Boot input to activate the CAN bootloader for firmware upload
(see section
6.2 Preparing Hardware on page 22
)
Serial and debugging ports of the microcontroller (see section
Hardware Configurations on page 12)
The following subsections describe each connector assignment.
2.1
D-Sub Connectors (IPEH-002210/-11)
The two D-Sub connectors are provided for the CAN channels CAN1
and CAN2. The CAN lines (CAN_H, CAN_L) are arranged according
to the CiA® 303-1 specification.
The power supply of the PCAN-Router can be provided via both D-
Sub connectors. The opto-decoupled version (IPEH-002211) can
only be supplied via CAN1. The supply connections U
b1
and U
b2
are
connected internally without feedback. Thus, different voltage
sources can be connected.
With the D-Sub connector CAN1, the bootloader for the firmware
upload can be additionally activated via pin 6. The channel CAN1
(IPEH-002210) or CAN2 (IPEH-002211) additionally contains a digital
input named
Din0
, which can be evaluated by the microcontroller.
