4.2.8 USB Data Cables
It is recommended that the USB 1.5 meter data cable HKN6163_ is used for both dash mount 
configurations (at J2 connector) and for remote mount configurations (at J100 connector). This is 
because the HKN6163_ has the emergency jumper present, which is necessary for correct dash 
mount configurations. For interfacing at the MMP port, use Cable HKN6184_ which is a USB device 
cable.
The USB 4 meter (15 feet) data cable enable HKN6172_ is recommended for remote mount 
configurations only (at J100).
If the customer intends to use the HKN6172_ for dash mount configurations (at J2), the cable’s  
26-pin connector must be opened and an emergency jumper-wire placed across pins 14 and 15. 
Refer to Figure 4-1.
4.2.9 RS232 Cables
The following are RS232 cables. Although not compatible with CPS radio reading or programming, 
they can be used for interfacing with RS232 accessories or RS232 computer programs. HKN6122_ 
is an RS232 serial COM port computer interface cable from J600 connector. HKN6160_ is a 6 feet 
dash RS232 cable from J2 connector. HKN6161_ is a 20 feet dash RS232 cable from J2 connector. 
HKN6183_ is a 4 meter cable from MMP connector.
4.3 Vehicle Interface Port Overview
The Vehicle Interface Port (VIP) allows the control head to operate outside circuits and to receive 
inputs from outside the control head. There are three VIP outputs which are used for relay control. 
There are also three VIP inputs which accept inputs from switches (remote mount only).
