Page 15: Why Setup The Windows
If you are running the CDS-9020 from a battery source and want to maximize your battery life, you want the battery to last as long as possible. You will need to figure out when you will be calling the CDS-9020, and set the polling windows to correspond with those times. -

With the CDS-9020 you do need to short together DTR and DSR the AT&D0 does the same thing for you. If you feel you need to, it will not affect your data. Shorting together JP2 DTR to DSR the current goes up about 7ma more when waiting for a call. -

Page 30: What Is Cdma
WHAT IS CDMA (Code Division Multiple Access) A method for transmitting real- time signals over a shared portion of the spectrum. The foremost application of CDMA is the digital cellular pho ne technology from QUALCOMM that operates in the 800MHz band and 1.9GHz PCS band. CDMA phones are noted for their excellent call quality and low current draw. - Page 31 combined and modulated onto a carrier frequency in the 800 MHz range. At the receiving side, the received signals are quantized (tur ned into bits) and run through the Walsh code and PN sequence correlation receiver to recover the transmitted bits of the original signal. When 20ms of voice data is received, a Viterbi decoder corrects the errors using the convolutional code, and that all goes to the vocoder which turns the bits back into waveforms (sound).

Page 32: Rs-232 Characteristics
RS-232 CHARACTERISTICS RS-232 Signals Functional Description General: The first letter of the EIA signal name categorizes the signal into one of five groups, each representing a different "circuit": • A - Ground • B - Data • C - Control •... - Page 33 • 3 Receive Data Name: BB Direction: DTE <- DCE CCITT: 104 Serial data (primary) is sent on this line from the DCE to the DTE. This pin is held at logic 1 (Mark) when no data are being transmitted, and is held "Off" for a brief interval after an "On" to "Off" transition on the Request To Send line, in order to allow the transmission to complete.
- Page 34 • 6 Data Set Ready Name: CC Direction: DTE <- DCE CCITT: 107 On this line the DCE tells the DTE that the communication channel is available (i.e., in an automatic calling system, the DCE (modem) is not in the dial, test or talk modes and therefore is available for transmission and reception). It reflects the status of the local data set and does not indicate that an actual link has been established with any remote data equipment.

Page 35: Trouble Shooting Problems
Signals traveling along the cable are attenuated and distorted as they pass. Attenuation increases as the length of the cable increases. This effect is largely due to the electrical capacitance of the cable. The maximum load capacitance is specified as 2500pf (picofarad) by the standard. The capacitance of one meter of cable is typically around 130pf, thus the maximum cable length is limited to around 17 meters. - Page 36 ESN make sure it matches yours, also get the their System ID Number and make sure that’s correct. See if the CDS-9020 can dial-out, call a phone number to see if it rings. Use the ATDT command from a terminal program).
