Description of pins:
1. DTR. Data Terminal Ready.
When open or connected to + Voltage the unit is ready for normal transfer mode.
When connected to Ground the unit goes to low current consumption mode.
OFF<2.7V. ON>3V-30V.
2. Port 2. CTS. Clear To Send.
TTL-Signal from modem to DTE.
3. Port 2. RD. Receive data.
TTL-Signal from modem to DTE. Asynchronous serial data.
4. Port 2. TD. Transmit data.
TTL-Signal from DTE to modem. Asynchronous serial data.
5. Port 2. RTS. Request to Send.
TTL-Signal from DTE to modem.
6. Port 1. CTS. Clear To Send.
Signal from modem to DTE.
7, 8. GND. Ground
Main voltage minus. Signal and chassis ground.
9. Port. 1. RD, Receive Data.
RS-232 Signal from modem to DTE. Asynchronous serial data.
10. Not Connected.
11. Port 1. TD, Transmit Data
RS-232 Signal from DTE to modem. Asynchronous serial data.
12. MODE.
Programming pin. When connected to + Voltage the unit is in normal mode. When connected
to Ground the unit is in programming mode.
13. Port 1. RTS, Request To Send
Signal from DTE to modem.
14, 15. PWR
+VDC. Main voltage input. The radio module is designed for 6-30VDC +/- 5%.
NOTE!
Port definition. Port 1 or 2 can be defined using the Configuration Manager. When the Program
switch of the adapter is switched ON (Programming-mode) the default Port is always Port 1.
When the Port has been defined, it’ll be activated by switching the Power OFF-ON, or switching
the Program Switch switched to OFF.
