Multi-Tech Systems, Inc. CDMA C1 AT Commands Reference Guide (PN S000478C)
Commands (Not for IP and GPS
This command is used to configure the low limit and high limit diagnostic values of the primary
and secondary (diversity or GPS) antenna. The values are compared to the ADC reading from
the antenna diagnostic voltage divider network. The current antenna status (NORMAL, OPEN, or
SHORTED) is derived from comparison to these limits.
The ADC used to read the antenna diagnostic voltage divider network for the primary antenna
may be selected using the AT+WANTADC command.
The secondary antenna has two sets of low/high limits—one for the non-powered state and one
for the powered state. The secondary antenna is powered when the setting of AT+WANT=1. For
hardware revisions 2.1 and later, the non-powered low/high limits of the secondary antenna are
not applicable. Use the +WHWV command to determine the hardware version of your device.
The limit settings are persistent across power cycles.
