2.1 Installation Steps

Below are the basic steps for installing the transceiver. In most cases,

these steps alone are sufficient to complete the installation. More

detailed explanations appear at the end of these steps.

1. Mount the transceiver to a stable surface using the brackets supplied

with the radio.

2. Install the antenna and feedline for the station. Point directional

antennas in the direction of the associated network’s Master Station.

3. Connect the data equipment to the transceiver’s

DATA INTERFACE

connector. Use only the required pins for the application—Do not

use a fully pinned (25-conductor) cable. Basic applications might

require only the use of Pin 2 (Transmit Data—TXD), Pin 3

(Received Data—RXD) and Pin 7 (Signal Ground). The radio can

be keyed by using the

DATAKEY command.

Additional connections might be required for some installations.

Refer to the complete list of pin functions provided in Table 6 on

Page 10.

4. Measure and install the primary power for the radio. The red wire on

the GE MDS-provided power cable is the positive lead; the black is

negative.

Only use the MDS 4710/9710 radio transceivers in nega-

tive-ground systems.

Connection to a positive-ground system or an accidental reversal

of the power leads can damage the transceiver.

5. Set the radio conﬁguration. In most cases, the transceiver requires

only minimal software conﬁguration. The selections that must be

made for new installations are:

• Transmit frequency (“TX [xxx.xxxx]” on Page 28)

• Receive frequency (“RX [xxx.xxxx]” on Page 26)

The operating frequencies are not set at the factory unless they were

speciﬁed at the time of order. Determine the transmit and receive

frequencies to be used, and follow the steps below to program them.

6. Connect a hand-held terminal (HHT) to the

DIAG. (diagnostic) con-

nector. When the HHT beeps, press to receive the ready “>”

prompt.
