TransCore 05716 Manuel D’Utilisation

A dedicated electrical power supply must be present at the site and available to the 
MPRR at all times. The power must be 16-20V AC or 16-28V DC. A step-down trans-
former is available (North America only) to convert a 120V AC duplex wall outlet 
with ground to 18V AC, as is a step-up transformer to convert a low-voltage 12V AC 
outlet to 18V AC. Consult your local and national electrical codes for installation and 
safety requirements.

If 18V AC or 18V DC power is available, the transformer option is unnecessary.

TransCore offers a Class C transformer accessory kit (part number 76-1620-005) for 
sites where 110V AC is available. It is the installer’s responsibility to supply conver-
sion equipment and wiring for other voltages.

Power circuits are protected internally against power surges. 

Your site design must include communications between the MPRR and a host device. 
The MPRR communicates with the host device through an asynchronous serial line. 
This serial line is an RS
