Serial Port (Models 1353-4101 and 1353-6101 only)
On selected models, Pins 11 & 12 can be congured as a serial port or as analog inputs via SDO. e
Curtis programmer can connect to this serial port using pins 11 & 12 along with I/O GND (Pin 4)
and +12V supply (Pin 10); see wiring diagram, Figure3. e Curtis Model 840 also can be connected
to this port.

Auxiliary Power Supplies
e 1353 provides +12V and +5V auxiliary output power for low power circuits such as a ngertip
joystick, electronic throttle, Curtis programmer, or remote I/O boards. e return line for these low
power circuits is I/O GND (Pin 4). e maximum total combined output current is 200 mA.

CANbus Interface
e CANbus interface will comply with CAN2.0B, active from 50 kbit/s to 1Mbsp communication rate.
The 1353 will be terminated by an internal 1 kΩ resistor across the CAN High and Low
communication pins. is assumes a mid-truck connection (not end-of-line). If the 1353 is placed at
the end of the communication lines, an external 120 Ω, ½ W resistor must be added across the lines.
Power
e power pins are each capable of carrying up to 9 A. Every application must use B+ (Pin 1) and
one or both of the B- connections (Pins 2, 9).
Since the 1353’s nine drivers can sink a maximum combined load of 18 A, you will need to determine
the application’s maximum total loading on B-. To prevent the pin from overheating, the proper
wire gauge must be used and, if the load is greater than 9 A, both B- pins connections are required.
If it is determined that both B- pins are required, you must also determine the load on B+. is
requires either knowledge of the expected PWM or actual in-application measurements. The
combined average current recirculating through the B+ pin cannot exceed 9 A. is can be an issue
if the inductive loads are specied at a lower voltage than the battery supply as the applied PWM
would normally be reduced so as not to exceed the average applied voltage or current. e lower
PWM in turn raises the average current owing theourgh the B+ pin as the load current recirculates
for a greater portion of the PWM period.
