Introduction:

HCP HIT is a new line of modems that enables data, fax or SMS applications.

Basically there are 2 different options. HIT modem can be with RS232 or USB interface connection based on Cinterion MC55 module.

So next options are available:

HIT 55 RS232 is triple band modem based on Cinterion MC55 with RS232 interface and integrated TCP/IP stack available via AT commands

HIT 55 USB is triple band modem based on Cinterion MC55 with USB interface and integrated TCP/IP stack available via AT commands

All types have push-push slot for SIM card, external SMA connector for GSM antenna and internal hardware watchdog circuit that keeps the modem turned on.

All these features packed in a robust metal housing makes HIT ideal solution for industrial as well as home appliances.

General features:

• Supply voltage range: 7-30V (RS232 version)

• Robust industrial housing

• Dimensions: 78 x 54 x 26mm

• Wight approx. 170gr

• Ambient temperature range: -20 to +60 °C

4. Power supply ratings

HIT modems with RS232 interface require external power supply and HIT modems with

USB interface are supplied trough USB and do not require external power supply.

6. USB interface description

For applications where RS232 connection is not available, USB modem version can be used.

USB modem is used in a similar manner as it is connected to the standard RS232 COM port because USB modem is installed as USB to serial converter.
