16-Lead Header Connector Pinout

PIN # Signal Designator Signal name Description I/O Comments
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. Mainte-

nance 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 successfully 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 RES CONT RESCONT TTL Input Reset the radio Reset the radio by shortening this pin to the ground.
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 VCC36 PWR External Power Supply Regulated positive 3.6V DC from ext. Power Supply.
16 VCC36 PWR External Power Supply Regulated positive 3.6V DC from ext. Power Supply.
