CONNECTING TO A PC

CONNECTING VIA THE SERIAL PORT

The PC serial port on the rear of the CellCom basestation is mainly

used for firmware version upgrades of the system.

A specially wired cable is required for these updates, consisting of two

9-pin D-type connectors for the PC and the CellCom ends. On the

CellCom end, a male 9-pin D connector is used, and is wired as

follows in relation to the D connector pins on the PC end. Pin 2 goes to

pin 3, pin 3 goes to pin 2, and pin 5 goes to pin 5; in other words, the

data Tx and Rx lines on pins 2 and 3 are reversed. Those are the only

wiring connections on the CellCom end of the cable.

Table 4-6: Pinout for Cable to Upgrade Basestation Firmware

On the PC end, a female 9-pin D connector is used. Make sure that the

data connections of pin 2 to pin 3 and pin 3 to pin 2 are followed, and

that pin 5 goes through to pin 5. Then short pins 1, 4, 6, and 8 together

on the PC end of the cable. The cable will now be ready to use with the

any upgrade files from the factory. Table 4-6 gives the pin configuration

for this cable. Table 4-7 shows the pin configuration for the cable used

to upgrade beltpack firmware.
