Signal desig-
nator
Signal name I/O Description Description
1 GND GND - Ground Signal and Chassis Ground
2 DSP UART 1 TXD TTL Input Transmitted Data Serial Data Input
3 DSP UART 2 RXD TTL Output Received Data Output for received serial data
4 DPORT5 DTR or DP/MP TTL Input Data Terminal Ready
Control line can be used as a backup method for entering
Command mode:
(0V) – Maintenance Mode; (3.3V) – Data Mode
An internal 100K pull-up enables Data Mode if this
signal is left unconnected. Maintenance Mode is also
accessible by transmitting an escape sequence.
5 DPORT1 CTS TTL Output Clear to Send
Used to control transmit flow from the user to the radio:
(0V) – Transmit buffer not full, continue transmitting
(3.3V) – Transmit buffer full, stop transmitting
6 TTLI1 SLEEP TTL Input
Sleeps/wakes radio
Receive only
In sleep mode, all radio functions are disabled consuming
less than 50µA. An internal 10K pull-down wakes up the
radio if this signal is left unconnected. At wake up, any
user programmed configuration settings are refreshed
from flash memory, clearing any temporary settings that
may have been set:
(3.3V) – Sleep Radio; (0V) – Wake Radio
As an option could be used as TTL Input Line 1.
7 DPORT3 MDM_GRN TTL Output Data Carrier Detect
Used by remotes to indicate that the remote has success-
fully acquired the signal from base station:
(0V) – Carrier detected (synchronized)
(3.3V) – No carrier detected (not synchronized)
8 DPORT4 RTS TTL Input Request to Send
Gates the flow of receive data from the radio to the user
on or off. An internal 10K pull-down enables data receive
if this signal is left unconnected. In normal operation, this
signal should be asserted:
(0V) – Receive data (RxD) enabled
(3.3V) – Receive data (RxD) disabled
9 DPORT2 DSR TTL Output Data Set Ready
Used to control transmit flow from the user to the radio:
(0V) – Receive buffer has data to transfer;
(3.3V) – Receive buffer is empty
10 ANT_DC ANT_DC Power Input
External Power for
Antenna LNA
External Power for Antenna LNA +5...+15 VDC
11 TTLO1 TTLOUT1 TTL Output TTL Output Line 1 Reserve line
12 TTLO2 TTLOUT2 TTL Output TTL Output Line 2 Reserve line
13 GND GND - Ground Signal and Chassis Ground
14 TTLI2 TTLIN TTL Input TTL Input line An internal 100K pull-up resistor is applied.
15 VCC42 PWR External Power Supply Regulated positive 4.2V DC from ext. Power Supply.
16 VCC42 PWR External Power Supply Regulated positive 4.2V DC from ext. Power Supply.
