Section 2. Radiotelemetry Network Components
The lights can also be used to verify the appropriate power up sequence of the
RF500M. View the indicator lights while applying power with the power
adapter or connecting the datalogger to the RF500M CS I/O Port with an SC12
cable. The sequence of the lights flashing after connection indicates the power
up self-test status. Both lights should cycle through a combination of colors
and then turn off to indicate the RF500M has powered up correctly and is
ready for operation.
2.1.5 RF500M Connections
The CS I/O port is normally used to connect the RF500M to the datalogger
with an SC12 cable. Table 2-1 describes the 9-pin connections. A null modem
cable with female end connectors (CSI Part Number: 13657) is used to connect
the RS-232 port of the RF500M to the PC. The 10-pin rectangular connector
is for connection to the transceiver interface.
TABLE 2-1. RF500M CS I/O to Datalogger Connector
Description
Pin Description
1 +5 V: Not Used
2 GND: Ground
3 Ring: Ring to Datalogger
4 RXD: Transmit from RF500M
5 ME: Modem Enable from Datalogger
6 SDE: Synchronous Device Enable
7 CLK/HS: Clock/Handshake from Datalogger
8 +12V: Supply from External Source
9 TXD: Received by RF500M
2.2 RF500M Compatible Radios
2.2.1 Analog Radio Description
The RF500M is compatible with the following analog radios: RF310 series,
RF300 series, and unmodified DataRadio DL-3400 radios.
The radios are connected to the RF modem by a special radio cable. The 9-pin
connector has a red and black wire coming out of the connector. The 9-pin
connector should be connected to the radio. The red and black power wires
should be connected to 12V and Ground respectfully. The 10-pin connector
should be connected to the RF modem.
