GSM/GPRS or CDMA Wireless Modem Top Board (Optional)
Fig. 6.9.1. NetGuardian G5 wireless modem option.
You can order your NetGuardian G5 with an optional GSM/GPRS or CDMA wireless modem, which provides
wireless network connection. (See Figure 6.9.1.). The wireless modem is powered by the same –48 VDC power
as the NetGuardian, which provides more secure, more robust operation than modems that run off commercial
power.
To power and activate the wireless modem top board, insert the provided 1/4 amp fuse in the wireless
modems fuse socket. (See Figure 6.9.1.) If you ever want to turn off power to the wireless modem, just remove
the fuse.
You may use any service provider you choose for your wireless connectivity.
